Dog fever symptoms: how do I know, and what helps at home?

The short answer

Check your dog's temperature with a thermometer; a warm, dry nose proves nothing.

Normal: up to 102.5°F (39.2°C). From 103°F (39.4°C), a vet finds the cause.

Signs of fever in a dog

  • Dog is quiet, hides or skips walks
  • Dog refuses food, shivers or seems tired
  • A warm, dry nose alone does not mean fever
  • Mild fever after vaccine: a day or two is normal

How to check a dog's fever

  • Use a digital thermometer in the dog's anus
  • Oil the thermometer tip; slide in about 1 inch
  • Normal dog temperature: 100 to 102.5°F (37.8 to 39.2°C)
  • Excited or just back from a walk? Recheck once calm

Help a dog with fever at home

  • Let the dog rest; skip walks and play
  • Offer small sips of water often; never force the dog
  • Look for ticks; tell the vet about any recent ticks

Never give a dog with fever

  • Human fever tablets: paracetamol, ibuprofen, aspirin, never on your own
  • Anything else from your medicine box
  • Leftover antibiotics, or a dose copied from another dog

When help can’t wait
