Causes of a high temperature in a dog. What body temperature is considered normal for a dog? Symptoms of fever in dogs

Once you determine that your dog has a fever, you can begin treatment promptly and prevent further deterioration of his condition. Although the only one reliable way While measuring a dog's body temperature involves using a rectal thermometer, knowing how to quickly determine your dog's fever without using a thermometer can be of great benefit.

Steps

Part 1

Assessing a Dog's Body Temperature

Touch the dog's ears and paws. A dog with a fever will usually have very hot ears and paws. You can assess its temperature by touching your pet's ears and paws with sensitive areas of your body - the cheek or back side hands. Is your dog's skin warmer than yours? U healthy dog body temperature is only slightly higher than that of humans.

There is a lot in a dog's ears and paws blood vessels, and when she has a fever, these parts of the body become hot due to the movement of cells immune system to those areas where there is infection. Increased circulation of these cells in the blood leads to the release of additional heat in the blood vessels.
If right and left ear have different temperatures, this is a deviation from the norm. Usually, if one ear is warmer than the other, this is more likely a sign local inflammation ear than general fever.

Touch the dog's nose. If she has greenish or yellowish discharge from the nose, the dog probably has a fever and an infection. This type of discharge may indicate that your dog's body is fighting a respiratory infection, although this will only become clear over time. serious cases. Certain diseases, for example, canine distemper and adenovirosis (the so-called kennel cough) also have similar Clinical signs. Therefore, if you notice greenish or yellowish nasal discharge in your dog, take him to the vet immediately.
- Temperature and humidity in the body healthy dog vary within certain limits. It is a myth that dogs always have a cold and wet nose. In fact, the nose can be dry for several reasons: for example, if the dog lies in the sun, after sleeping near a radiator or after exercise, or when its body is dehydrated. What kind of nose does your dog usually have? Has she done any of the above that may have caused her nose to become dry and hot?
Feel the dog's armpits and groin area. With fever and infection, these areas are usually swollen and hot. You can test with the back of your hand to see if it's hot. The lymph nodes in the armpits and groin area. But in order for you to feel the temperature correctly, your hands must have normal temperature and not be cold or hot.
- Lymph nodes contain immune system cells that fight bacteria and viruses. They protect the blood by filtering causing infection microorganisms: when an infection enters the body, the lymph nodes prevent its spread. At the same time, they are filled with cells of the immune system that secrete various substances, which when they enter the brain initiate an increase in temperature. As a result of the simultaneous occurrence of various protective reactions, the lymph nodes become inflamed, swelling and heating up.
- Since dogs have very little hair in the armpit and groin area, it is easy to check whether they are hot or not.
Examine your dog's gums. If she has a fever, her gums may feel warm and dry to the touch. Another important sign- This is redness of the gums, especially if they are brick-red in color. This may indicate high temperature or even sepsis.
- If the dog healthy gums, they should be moist, shiny and almost the same Pink colour, like human gums. Lift up upper lip dogs at upper canine and touch the tip index finger to the gum, testing how hot and wet it is. Is its color, temperature and humidity almost the same as yours? If not, your dog may have an infection.
The dog may also have a low temperature. If she has health problems or is in shock, her body temperature may be downgraded. She may also experience physiological adaptations to the temperature, such as shivering and goosebumps. Animal with excessive low temperature the body may be very lethargic and greatly weakened. In this case, contact your veterinarian immediately.
- Keep in mind that a dog shivering does not always mean its body temperature is low; it may be a response to stress, fear or pain. If you don't know why your dog is shaking, contact your veterinarian as soon as possible.

Assessing a dog's appearance
1. Look for other signs of fever. In addition to body temperature, a dog may exhibit other symptoms. physical signs heat. It is important to be attentive and notice changes in normal behavior And physiological processes– from difficulty defecating to coughing and sneezing, as these signs may indicate an infection. TO possible symptoms relate:
  - Poor appetite
  - Lethargy, sluggishness and passivity
  - Weakness
  - Vomit
  - Stomach upset
  - Sleep all day
  - Desire to be alone from other dogs
2. Watch appearance and the dog's behavior. If your dog has a very high temperature, you will be able to feel the heat emanating from his body while being about half a meter away from him and without even touching him. You may notice a number of other symptoms listed below.
  - The dog may have long periods shortness of breath, and you will feel her hot breath on your cheek.
  - The animal may feel thirsty and drink more than usual, as it loses its breath when it is short of breath. a large number of liquids.
  - Fever may cause joint pain. This manifests itself in the dog avoiding physical activity, she has difficulty getting up, walks slowly and awkwardly, or even has a limp.
  - When the temperature is high, your pet will be withdrawn, quiet and lethargic. Feeling uncomfortable and irritated, the dog may also show unusual aggression when touched.
  - The dog does not want to take care of his appearance, and his coat seems disheveled and unkempt, excessively dry or greasy.
3. Pet the dog, play with it a little, trying to involve it in the game. Remember what your pet looks like when he healthy. Is his body warmer than usual? Are your eyes dull? Is the coat less silky? Is your dog less active and responsive than usual? These changes in physical condition and behavior may indicate illness.
  
  If your dog seems fine, check his condition again after an hour. If her body is hot but she is not showing any signs of illness and her behavior is normal, allow her to rest in a cool place for an hour and then check her temperature again. Since fever is a natural defense reaction of the body, it may be enough to just wait it out if there is nothing serious.
  - Remember, if the temperature of the extremities increases and the animal behaves unnaturally, this is more serious than an elevated temperature in a dog that otherwise appears completely healthy. In this case, you should not worry about a high temperature, but about an infection.

  Causes of fever in dogs
  1. Fever is a normal protective reaction of the body. In most cases, it does not pose much of a threat. On the contrary, an elevated temperature often indicates that the body is fighting an infection or recovering. However, in some cases, fever may be a sign bacterial infection. If your dog exhibits any unusual symptoms, contact your veterinarian immediately.
    
    If in doubt, contact your veterinarian to get a professional diagnosis. If symptoms are present, action must be taken; Fever should be taken especially seriously if it lasts more than 24 hours. Your veterinarian may be able to prescribe an antipyretic to help bring your temperature down very quickly.
  2. Take into account other ailments, causing an increase temperature. If your dog's fever is associated with another, often more serious, medical condition, you will notice a corresponding set of symptoms. This may be a serious respiratory or gastrointestinal infection. Keep the following in mind:
    - When respiratory infection dogs tend to cough and sneeze, have a runny nose and watery eyes. This often negatively affects the animal’s activity and sleep.
    - With a gastrointestinal infection or inflammation, the dog may lack appetite and often suffer from vomiting or an upset stomach. If you suspect your dog has a gastrointestinal infection, take him outside when he needs to go to the bathroom to monitor his stool and urine. Does she have an upset stomach? Is there blood in her urine?
    - If you notice any of the above problems, consult your veterinarian immediately. There is a possibility that the animal’s body is infected; Fever is just one of many symptoms to look out for.

If the dog is sick...

A high temperature in a dog exceeding 39.5°C (lower) can be caused by the following main reasons.

The beginning of the body’s protective function, designed to protect it, for example, from harmful pathogens of various diseases (viruses, microbes, etc.) that have invaded the animal’s body. In other words, an elevated temperature often indicates that your pet is sick. Logical, right? Moreover this symptom indicates very serious illness, which may represent inflammatory process(wounds, abscesses, arthritis, etc.) or the presence dangerous infection. Of course, there are exceptions when protective function turns on not because of an illness, but because of a recent vaccination, a sudden allergy, or a severe one.

Creating conditions under which the dog is exposed to extreme heat(heat outside, too warm room, etc.), as a result of which he begins to suffer from heatstroke or sunstroke.

Banal stressful situation (of course, if the dog has a temperature of 40 and above, stress cannot be the cause; in 99% of cases this indicates that the body is not able to cope with the disease on its own and needs urgent help health care!), such as, for example:

change of owner, moving to new family or to a new home,
trips to unfamiliar places,
psychological and physical stress that the dog is unable to cope with (rough treatment, participation in exhibitions),
and, finally, a trip to the veterinary clinic is an event that does not bring joy to any animal (in this situation, to receive correct result, it is recommended to measure the temperature again after an hour and a half, that is, after the “patient” slightly adapts to the new environment and stops worrying too much).

In the second and third cases, it is enough to simply exclude the factors causing negative reaction eg: do not allow the dog to be in the sun long time and regularly ventilate the room in which she lives, or try to change the situation that led to severe stress.

If you find that your dog’s temperature, the treatment of which should be started immediately, could not be caused by either heat or stress, then your pet is sick. What is the right thing to do in this case?

Firstly, It is not recommended to lower your temperature yourself using any medications, since, without a doctor’s prescription, such methods can cause more harm to your pet than good. But you can alleviate your dog’s condition in the following ways:

offer her slightly chilled water;
stroke it with a hand dipped in cold water;
apply an ice bottle wrapped in a thin towel to the inner thighs;
create a shade around it (that is, protect it from the sun) or open the windows.

Secondly, try to determine if your pet has any other obvious signs of illness. For example, if a dog has a temperature of 39, weakness and refuses to eat, we can conclude that it is not healthy, although 39 degrees is the norm. Any unusual behavior of the animal should alert the owner.

Thirdly, be sure to visit a veterinarian. As you understand, knowing only that the dog is sick, you cannot help him. It is necessary to conduct research and take tests to determine the correct diagnosis and prescribe treatment. To do this you will need:

carefully examine the animal;
examine the body for infections;
take a urine and blood test;
conduct an ultrasound examination;
perform x-rays and other procedures at the discretion of the therapist.

Only after the disease is identified will the doctor be able to prescribe treatment. As a rule, at high temperatures, first of all, antipyretic drugs suitable for a particular patient are used, and droppers are placed to prevent dehydration and other dangerous consequences.

Most importantly, do not under any circumstances ignore an increase in your pet’s temperature, as this in itself can lead to dire consequences, such as:

convulsions;
fainting;
disruption of the functioning of vital organs;
frequent (or intermittent) heartbeat;
severe diarrhea with vomiting;
intestinal and other bleeding;
death.

If there is no way to immediately contact a specialist, you can bring down the temperature with intramuscular injection made into the thigh. Take 0.5 ml of diphenhydramine, 1 ml of noshpa, 2 ml of analgin and draw these drugs in the indicated proportions into one syringe. For small breed dogs and puppies you need to take half the dose. Remember that this is emergency help! Such an injection cannot cure a dog; it will only bring temporary relief, but the cause that caused the illness will not go away.

Body temperatures – important indicator the health status of the animal. This is one of the first signs indicating that the dog’s body needs help. With few physiological reasons temperature fluctuations, many more pathologies leading to this, which only a veterinary specialist can help understand.

Normal body temperature in dogs

Normal temperature readings for dogs are not the same as for humans and fluctuate between 37.7-39°C.
IN individual situations limits can be extended from 37.5 to 39.3° WITH.
On average, temperature rise above 39°C in adults this is no longer the norm.
Moreover, a gradual increase in temperature is much more dangerous than sharp jumps, because The vigilance of the immune system is literally “put to sleep” and the fight against the cause of the fever does not occur immediately.

A dog’s temperature (normal) depends on:

age(the older you are, the lower the performance physiological norm– in small puppies it is considered normal up to 39.2°C, in old puppies it can be in the range of 37.3-37.8°C);
gender(the temperature of females is slightly higher than that of males due to the peculiarities of hormonal regulation);
breed characteristics(in dogs small breeds indicators are slightly higher than for large ones at the same age);
physiological state (pregnancy, estrus, recovery from illness, etc. factors provoke fluctuations in indicators in one direction or another).

Temperature of dogs, depending on age and size of breed:

Physiologically, temperature indicators increase:

in hot weather conditions;
during periods of stress or anxiety;
from prolonged physical activity;
during estrus;
after eating food.

How to measure a dog's temperature?

The following instruments may be needed to measure temperature:

classical mercury thermometer or veterinary;
Digital Thermometer;
rectal (mercury or electronic) thermometer;
infrared ear thermometer.

It is ideal if the animal has its own personal measuring device that is not used by humans.

Typically, the thermometry procedure does not cause discomfort in a dog, but an assistant will not hurt, especially if the dog is a large breed.

In small dogs The temperature is measured in a lying position - on your side or stomach. If there is an assistant, he lightly presses the animal to any horizontal surface, and someone else measures it. If there is no assistant, then the dog is placed crosswise on the knees, the tail is held along the entire length with one hand and moved to the side, and the thermometer is inserted with the other hand.
U big dogs It is better to carry out thermometry together, and the pet should know at least one person very well (for example, the owner). One person holds the dog by the neck and the girth of the body, the second inserts a thermometer. Large breeds must be muzzled or with the mouth fixed with a rope loop using an ordinary bandage (single knot on top, twist on the bottom and fixation on the back of the head below the ears).
End of the measuring instrument Before starting measurements, lubricate with greasy cream, glycerin or petroleum jelly.
Tail carefully moved to the side and with a gentle rotational movement from side to side, the thermometer is inserted into the rectum to a depth of 1-2 cm, depending on the size of the pet.
Digital Thermometer aged until sound signal, classic mercury– time 3-5 minutes; infrared ear The result is produced almost instantly.
After removing the thermometer from the rectum, its tip must be wiped with a swab moistened with any disinfectant solution.

During the procedure, you need to talk to the dog in a soft, relaxed voice. You can train your pet to use commands such as “heal” or “thermometer”, because the procedure must be carried out on a regular basis. At the end, you can give any treat, praising for good behavior at the time of thermometry.

Unlike cats, dogs have places on their bodies where the owner can determine the presence of fever without resorting to instrumental thermometry. These places include the ears, armpits and groins, and gums.

Ears. By ears Numerous vessels pass through, which expand at high temperatures, giving higher degrees than usual. Both ears must be equally hot. An increase in fever is not a sign local temperature only one ear - this is more evidence of a local inflammatory process.
Armpit and inguinal cavities. Dogs don't have sweat glands in these areas, therefore increasing general temperature The body feels great there with a clear heat. During tactile measurement, a person’s hands should not be cold, so that there are no false hot sensations.
Gums. IN in good condition The dog's gums are moist and pink. If the animal begins to develop a fever, they become intensely red and, literally, almost dry.

Signs of an increase or decrease in a dog’s body temperature

There are a number of signs that should prompt the pet owner to conduct thermometry and find out body temperature. A decrease in body degrees (hypothermia) in a dog is just as dangerous as an increase (fever).

Signs of fever:

dry and hot nose(unless at night or after sleep);
lethargy and apathy;
refusal of food, and, sometimes, water;
pale and dry gums, tongue;
sometimes vomiting;
convulsions;
hard breath;
cardiopalmus.

Attention: dry and hot nose has diagnostic value, if only this phenomenon observed over a long period of time, and not episodically!

Signs of a decrease in temperature:

drowsiness;
shiver;
muscle tension;
slow heartbeat;
decreased blood pressure;
rare, shallow breathing;
inability to eat or drink even if desired.

Causes of fluctuations in body temperature in dogs

Change temperature indicators at pet- This is an indicator of ill health. Always treated not low or high performance, and their primary sources. Those. It is important to determine the reasons for the increase in temperature.

Possible reasons for an increase in a dog's body temperature:

The temperature drops when:

First aid for an increase or decrease in body temperature in a dog

High or low temperature is a sign that unfavorable changes have occurred in the dog’s health, i.e. is not independent disease, but a composite symptom. At home, you are allowed to independently influence its indicators only in cases where it is impossible to immediately visit a veterinarian or the pet’s life is threatened by critical numbers.

For fever

The dog does not sweat over the entire surface of its body, so it is very important to reduce the temperature as quickly as possible if it has reached a critical level. Self-medicated reduction in temperature will reduce clinical picture diseases, which will make it difficult to diagnose accurate diagnosis. Antipyretic drugs for humans act somewhat differently on dogs and can cause poisoning with fatal and internal bleeding.

Remember: dogs are not allowed to give paracetamol! Also, you should not give any other antipyretic drugs from a human first aid kit, and nothing without the prescription of a veterinary specialist.

If it is impossible to deliver the animal to a veterinary hospital, you can lower the temperature slightly on your own without medication:

Perform contact cooling. To do this, apply ice wrapped in a kitchen towel or any medium-weight cloth or tissue napkin to the neck area, inner thigh and paw pads.
In the absence of ice wet the animal's fur cool water including paw pads.
Be sure to give something to drink cool water (not cold!).
Place your pet in any cool place in the house(for example, in a bathroom with a tiled floor). Typically, dogs themselves look for such a place when they are feverish, which may initially serve as a signal that the pet should check its body temperature.

With all of the above procedures, it is usually possible to reduce body temperature below a critical limit in order to be able to reach a veterinary specialist.

For hypothermia

At home, when the temperature drops below normal, the dog needs to be literally warmed up. Place in a warm place, apply a heating pad with water to 38°C to the paws, cover with a woolen blanket, give water warm drink(milk, broth). After the temperature normalizes, a visit to the veterinarian remains necessary.

What does a veterinarian do?

For fever

When a dog is admitted to a veterinary hospital with an elevated body temperature, the veterinarian conducts an appointment in the classic sequence:

collecting a detailed medical history;
full clinical examination;
prescribing urine and blood tests;
X-ray and ultrasound diagnostics;
biopsy (if the situation requires it);
prescription of treatment according to the diagnosis.

The veterinarian always first conducts a full clinical examination, and then only, if necessary, resorts to medication to reduce the temperature.

If the animal comes already with critical temperature body, then the veterinarian carries out the usual appointment, only a little faster, in order to give an antipyretic injection after collecting maximum diagnostic information.

Reducing the temperature with medications is allowed only in cases where the indicator goes off scale above critical limits, namely above 40.5°C. To reduce it, you can use a mixture of solutions of no-shpa, analgin and diphenhydramine in a 1:1:1 ratio in one syringe, at a dosage of 0.1 ml/kg of each drug. That is, for example, an injection of 3 ml of a mixture is prepared for a dog weighing 10 kg: 1 ml of no-shpa + 1 ml of analgin + 1 ml of diphenhydramine.

At a temperature above 40.5°C, a threat to the dog’s life is already considered, so possible side effects of analgin are not taken into account (no-spa and diphenhydramine are included in the list of permitted free use in dogs, analgin is allowed with caution and under the supervision of a veterinarian).

For hypothermia

A decrease in body temperature below 36.5°C indicates that the dog’s strength to resist the disease has been exhausted, and the immune system is in a state of suppression. The animal requires resuscitation measures.

Depending on other symptoms accompanying hypothermia, the doctor prescribes warming therapy in the form of:

“warming” injections and droppers;
cardiovascular stimulation;
rubbing and massages.

Resuscitation will be carried out until body temperature is maintained within the physiological norm for 14-16 hours without drug assistance.

You cannot ignore any signs that are not typical of the daily condition and behavior of your pet. It is possible that the dog has a fever or the temperature has dropped and how quickly the pet recovers will depend on the speed of the meeting with the veterinarian and timely diagnosis.

Based on a dog's body temperature, you can assess its health status, but you cannot name a specific indicator - it is different for all breeds depending on the animal’s temperament and its physiological state. It is important to know your pet’s temperature norm in order to understand when deviations begin.

Normal temperature limits for dogs are considered to be from 37.5°C to 39.0°C. In puppies and dwarf breeds these figures will be slightly higher, up to 39.2 °C.

Important! If you want to determine the dog’s body temperature and find out whether it is healthy, your own subjective opinion cannot be an indicator, as well as determining the condition by the dog’s nose (whether it is wet or dry). Although, indeed, at elevated temperatures, a dog’s nose is usually dry.

Body temperature various breeds may also be different. Large animals tend to be “colder”. How smaller puppy, the higher its temperature thresholds. This is due to the fact that metabolic processes in small breeds occurs faster than in large breeds.

So, if you stick to the scheme, then approximate standards body temperature various dogs will fluctuate within the following limits:

Small breeds of dogs - adult animals have a body temperature from 38.5 to 39.0 ° C, puppies 38.6 to 39.3 ° C.
Average representatives - in adult animals the temperature norm is 37.5-39.0°C. In children 38.3-39.1°C.
Large dogs – adults from 37.4 to 38.3°C, puppies from 38.2 to 39.0°C.

In addition to the age and breed of the dog, body temperature can vary depending on weather, life circumstances, pregnancy, feeding puppies, etc. For example, in summer period and hot weather temperature standards may be overestimated by 0.5-1.5 ºС.

It will be possible to notice this based on pet behavior, he will look for a cooler place, breathe and drink often. The hot period of time is especially difficult to bear large breeds and dogs in old age.

IN prenatal period Bitches' body temperature decreases. If she gives birth at home, she should measure her body temperature more often to predict the moment of labor. About the beginning birth process a decrease in body temperature of a degree to one and a half will signal.

An animal's emotions can also contribute to changes in temperature readings. It could be joy, aggression, fear.

Therefore, the dog’s temperature is up to 39 ºС are not always pathologically justified. But everything is individual. If, along with these numbers, you notice a general malaise in your pet, then you should take the animal to the veterinarian.

Reasons for increased

Attention! At pathological changes in the dog's body, hyperthermia may be observed. In order not to immediately panic, you should figure out why the animal’s body temperature may increase.

Diseases

Most often, this phenomenon occurs in dogs during the following pathological changes in internal organs:

Swelling of the brain when damaged nerve endings and fibers.
Increased blood coagulation, problems with cardiac activity.
Shell death intestinal section from the inside.
Damage to the renal canals leading to organ failure.
Immune suppression.

The dog's painful condition can be affected by many factors. For example, summer heat, dry air and keeping an animal in a stuffy room can lead to heatstroke.

Another reason for increasing a dog's body is overdose medicines or exposure to toxic substances. For example, strychnine, anesthesia, organophosphorus compounds. Fever can develop with various infections.

Important! To measure a dog's body temperature, you need to use a tonometer, the tip of which is pre-lubricated with Vaseline and then inserted into anus animal to a depth of 1-2 cm. The duration of holding the tonometer will depend on its type.

Complications after castration or other surgery

This is another reason for an increase in body temperature in a dog. If you notice that postoperative sutures secrete fluid or bleed If the animal has hyperthermia, you should immediately inform your veterinarian about this.

Other reasons

The most common causes of body temperature in dogs above 39-40ºС relate:

Piroplasmosis.
Distemper in animals.
Endometritis in females.
In puppies, teething can affect their body temperature.
Stressful situations play an important role.
Animals can also suffer from allergies.
An abscess, most often it develops after various damages skin.
Joint inflammation.

What to do if it's high?

Treatment should be carried out if, along with elevated body temperature, there are also other symptoms of the disease, For example loose stool, lethargy, lack of shine in the eyes, refusal to eat, presence of blood in the stool, bad condition fur, etc.

Nursing dogs may be warmer than usual because their thoracic ducts a lot of milk. Limit standards can reach 39 ºС. But if the dog’s body temperature rises to 40 ºС and persists for a long time, then you should sound the alarm. Possible infection.

Is it possible to shoot down?

To lower the temperature or not to lower it is quite controversial issue. But what you need to do is call a veterinarian.

How and with what to reduce it at home?

If the dog’s condition leaves much to be desired, then you can bring down its temperature using the most gentle measures. For example, it will be enough to give an analgin tablet.

Attention! Medicines strong action It is prohibited to give without a doctor's prescription.

If you are sure that the cause of hyperthermia is teething, stress or an abscess, then You can bring down the temperature with this composition:

Mix one part of no-shpa and diphenhydramine and two parts of analgin.
Administer the composition by intramuscular injection.

But even this procedure must be carried out by a doctor. Self-medication can harm your pet:

The animal's condition may worsen.
Reduced body temperature by medication will make it difficult precise positioning diagnosis.

Why can't I give an ibuprofen or paracetamol tablet?

Sometimes the owner of an animal, in order to help his pet, begins to stuff him with medications intended for people, such as ibuprofen, ibuclin, etc. All of them belong to non-steroidal anti-inflammatory drugs and have a lot of side effects.

In animals, these medications can cause unpredictable complications, and they develop much more often than in humans. For example, even one tablet of ibuprofen can lead to stomach bleeding at the dog. And this is extremely dangerous complication, which leads to the death of the animal if medical assistance is not provided in a timely manner.

TO others side effects These medications may include:

vomiting;
malfunctions of the liver and kidneys;
confusion;
the occurrence of blood clots.

How to help your pet?

Hyperthermia in animals is not a disease, but a reaction of the body, and the owner’s task is to identify the pathology that caused the elevated temperature. A veterinarian can help with this. But for now
The doctor hasn't come, you shouldn't sit idly by. You can relieve your pet's condition by doing the following:

To make the temperature in the animal’s body function more easily, it is worth reduce the room temperature. To do this, ventilate the room or turn on the air conditioner. Ideal temperature standards for the room are 18-20 ºС. But you should avoid drafts, and the floor should not be cold.
Don't chase your animal, physical exercise at painful condition dogs should be kept to a minimum.
Try drink more the animal, even if it does not drink on its own, you do it, for example, with a syringe.
There is no need to feed the dog. If she refuses food.

Conclusion

Remember that you first need to determine the cause of hyperthermia, and only then apply therapeutic effects. But you can't handle it on your own, only a veterinarian can help you in this. Once the diagnosis is made, the doctor will prescribe adequate treatment for your pet.
