Can Dogs Eat Cat Food?

AVOID

AVOID — Cat food shouldn't be fed to dogs regularly, though a small accidental amount usually won't harm most dogs.

Commercial cat food, wet or dry, is made for cats. A few stolen bites are rarely a problem, but eating it regularly or in large amounts can cause stomach upset and, in some dogs, pancreatitis.

Main sources: PetMD — Can Dogs Eat Cat Food?

A small amount of cat food usually won't harm most dogs; watch for stomach upset. Contact your veterinarian if your dog ate a large amount, has had pancreatitis, or keeps eating the cat's food. If your dog vomits repeatedly, has a painful belly or is very quiet, contact a veterinarian, or an emergency veterinary clinic out of hours, straight away.

The full answer

This page covers commercial cat food, wet or dry, eaten by a dog. The veterinary guidance we reviewed doesn't distinguish between wet and dry cat food.

PetMD says a small amount of cat food won't cause problems for most dogs, but feeding it isn't recommended. Cat food is formulated for cats, not dogs.

Eating too much can cause vomiting and diarrhoea, and because cat food is rich, it may lead to pancreatitis in some dogs.

Risks and Things to Know

  • Stomach upset: vomiting and diarrhoea.
  • Pancreatitis in some dogs, especially with large amounts.
  • Weight gain if a dog regularly eats the cat's food.

How much is okay?

Not recommended as food or a treat. It's richer in fat and protein than dog food is meant to be. Feed cats where dogs can't reach their bowls.

How Should I Prepare It?

  • Not recommended in any form.
  • Keep cat bowls and food out of the dog's reach.

What If My Dog Ate Too Much?

If your dog ate a large amount of cat food, contact your veterinarian. If your dog vomits repeatedly, has a painful belly or is very quiet, contact a veterinarian, or an emergency veterinary clinic out of hours, straight away.
