The normal body temperature of a healthy dog is between 38 and 39 degrees Celsius. If the temperature rises above 39.5 degrees, this is known as a fever.

What can you do to help a dog with a fever?

If your dog has a fever, you should first offer him plenty of fresh water so that he doesn't become dehydrated. You can also give him some chicken broth or rice water to stabilize his electrolyte balance. However, avoid giving him solid food if he has no appetite.

You can also put a damp cloth on your dog's head or stomach to cool him down a little. However, make sure he doesn't freeze or shiver. You can also give him a hot water bottle or a blanket if he feels cold.

You should keep your dog in a calm and stress-free environment and give him plenty of rest and attention. However, avoid pampering or pestering him too much. Instead, let him decide at his own pace when he wants to play or cuddle.

When should you see a vet?

A fever is not always a reason to panic, but it should not be ignored either. If your dog's fever lasts longer than 24 hours or rises above 40 degrees, you should definitely consult a vet. This also applies if your dog shows other symptoms that could indicate a serious illness.

A vet can determine the exact cause of the fever and initiate the appropriate treatment. Depending on the case, your dog may be given antibiotics, painkillers, anti-inflammatories or other medication. In some cases, surgery or chemotherapy may also be necessary.

You should give your vet all the information you have about your dog, such as their medical history, vaccinations, diet and symptoms. This can help your vet to make the right diagnosis and choose the best treatment.
