How to Tell If a Dog Has a Fever? Top Tips

Like any other animals, canines get a fever that worsens their health. I got myself a dog which I have been rearing up for six months. It is a healthy and cheerful one. However, I have been noticing something unusual in my dog for two days.

It did not move as it used to. Besides, sometimes it started shivering for a long time. So I decided to take my dog to the vet.

Before I brought my dog there, I had some ideas about what could happen to my dog. But to my surprise, they told me my dog caught a fever.

If you are concerned if your dog is acting weird. Then, like me, you’ll want to know what happens to him. Here are a few ways you can check for fever signs:


In case you notice your dog doesn’t want to move, and it got lazy and shows no interest in going out for a walk, then, it may have a fever.

It is not obvious when a dog gets lethargic that it’s because it got a fever, but you should consider the worst case scenario. So if you see your dog not wanting to do anything, it could be a fever.


When a dog has hypothermia, it will start shivering and have other symptoms. Among them, you’ll find high fever.

Note that the normal temperature of a dog is in between 100.5 to 102.5 degree Fahrenheit. Puppies are more prone to hypothermia since they not have that much of defensive power in their bodies as grown-ups.

If you see your dog is shivering, then the first thing you can do is to take its temperature. If its temperature is below normal then before making any big step just go for something generic.

Try to warm up the room where your dog is or maybe provide it with something that can warm up its body. If the usual measures cannot solve the problem, then take your dog to a vet.


Hyperthermia is also a usual medical condition of the canines. If happens when your dog starts shaking due to high body temperature. It is caused by either an infection or maybe by heat stroke.

You can decrease your dog’s temperature by using some ice packs. If nothing works then take your pet to a vet to do some diagnosis and treatment.


This mostly happens because of fever and nasal discharge. Canine distemper is very much contagious and can quickly be passed on through all of its body secretions.

To be a bit precautious you can vaccinate your dog way before it happens. Point to be noted; vaccination is the only way to protect your dog from this disease since it can happen to your dog even if it does not socialize with others.

Heat Stroke

If your dog stays outside for a long time on a hot day, then it can certainly develop a fever, which you can infer if it has a heat stroke.

It is something that happens abruptly, and you will get little time to think through any possible solution. Hence, before ending up taking a misstep, take your dog to a nearby vet where it will be treated appropriately.

Causes of Dog Fever

  • Your dog can get a fever from a wound which is infected. It can be any sort of infection like ear infections, teeth infections, etc. Infection can be anywhere in its body, like the lungs, the brain or the kidneys.
  • Your dog can often catch a fever if it consumes something poisonous. For instance, human antidepressants, macadamia nuts, and other foods and medications may increase the dog's temperature.
  • If your dog has an ongoing bacterial or viral disease, then it can instigate fever as well.

How To Treat Your Dog’s Fever

  • In most of the cases, it will cure itself all by its own. If it has a fever from a viral infection, then it will take care of it by itself.
  • If the case is a bit more complicated, then you have to take more care of it. The dog needs to have antibiotics if it has bacterial infections. On the other hand if it has a fungal infection then giving the dog antifungals can be helpful.
  • Clean the infected wound properly and treat it with disinfectant.
  • If you cannot detect the cause of its fever, then take it to a vet immediately.


Sometimes you would not be able to determine the cause of your dog’s fever. This is called FUO or ‘fever of unknown origin.' In addition, there are many other reasons for which your dog can get a fever. Namely, tumors, metabolic diseases, different types of toxins and drugs, vomiting, and so on can be potential reasons.

Whatever be the reason, if you see any kind of abnormality in your dog, you should take necessary steps immediately until its condition gets worse. Your last resort to cure your dog can be taking it to a vet.

Just be sure to treat it before it’s too late. A fever can be potentially life-threatening, so never let a dog stay with one for too long.
