Can Dogs Get Fevers?
Above about 103F is a fever. Never give human medicine, and call your vet for a high or lasting one.
Yes, dogs can get fevers. A dog's normal body temperature is about 101 to 102.5 F, higher than a person's, so a reading above roughly 103 F counts as a fever. A fever is a sign the body is fighting something, whether an infection such as canine flu or inflammation. A high or persistent fever always needs a vet.
Signs of a Fever
| Sign | What you might notice |
|---|---|
| Low energy | Lethargy and less interest in everything |
| Loss of appetite | Turning away from food |
| Shivering | Trembling even when not cold |
| Warm, dry nose | A rough guide only, not reliable |
| Red eyes | Glassy or bloodshot appearance |
A raised temperature often rides along with common bugs like a cold, or with more serious ones such as pneumonia.
What to Do
- Take the temperature. Use a pet thermometer for an accurate reading.
- Offer water. Encourage your dog to drink and stay hydrated.
- Keep it cool. A comfortable, cool, quiet spot helps your dog rest.
- Skip human medicine. Do not give any over-the-counter drugs.
- Call your vet. Get advice on the cause and safe treatment.
Frequently Asked Questions
What is a normal temperature for a dog?
A healthy dog's body temperature runs about 101 to 102.5 F (38.3 to 39.2 C), noticeably higher than a person's. A reading above roughly 103 F is considered a fever, and 104 F or higher is serious and needs urgent veterinary attention.
How can I tell if my dog has a fever?
The only reliable way is a pet thermometer, ideally rectal. Warm, dry ears or a warm nose are not accurate signs. Other clues include shivering, low energy, loss of appetite, red eyes and a faster heartbeat, but these can accompany many illnesses.
Can I give my dog medicine for a fever?
No. Never give human fever medicines like ibuprofen, acetaminophen or aspirin to a dog, as they can be toxic and even fatal. If your dog has a fever, keep it comfortable and hydrated and call your vet, who can find the cause and prescribe safe treatment.
What causes a fever in dogs?
Fever is the body's response to something, most often an infection from bacteria, viruses or parasites, but also inflammation, an immune problem, certain toxins or a reaction to a recent vaccine. Because the causes vary so widely, a lasting or high fever should be checked by a vet.
⚠️ Emergency? If your dog may have swallowed something toxic or is seriously unwell, contact your vet or a pet poison helpline immediately (in the US, the Pet Poison Helpline is 855-764-7661).
