Dog not eating: what it means and when to call the vet

See a vet within 24 hours

A healthy dog skipping one meal is usually nothing to worry about. A dog that refuses food for more than 24 hours, or refuses food and is also vomiting, lethargic or in pain, should see a vet.

Common causes

  • Stomach upset from scavenging
  • Dental pain
  • Stress, heat or a change in routine
  • A swallowed object causing a blockage
  • Pancreatitis
  • Infection, kidney, liver or other illness

What you can do at home

  • Offer a small bland meal (plain chicken and rice)
  • Check the mouth for broken teeth or something stuck
  • Keep a note of what goes in and what comes out

What the vet may do

  1. Examination and blood tests
  2. X-rays or ultrasound for blockages
  3. Anti-sickness medicine and fluids

Prevention

  • Keep toys, socks and bins out of reach
  • Change food gradually

The details

Some dogs are simply fussy, especially small breeds that are offered many alternatives. The pattern that matters is a change: a normally keen eater who turns away from food, or a dog who wants to eat but then stops, which can point to mouth pain or nausea.
