Can Dogs Eat Grapefruit?

AVOID

AVOID — grapefruit flesh is not a classic dog poison, but it is very acidic and the peel and plant oils add extra concerns, so it is not a suitable treat.

We recommend not feeding grapefruit. The flesh is not toxic, but it is very sour and can irritate a dog's stomach, and the peel, rind and seeds contain essential oils and psoralens. A lick or a small bite of flesh is not a poisoning emergency.

If your dog has already eaten grapefruit, contact your veterinarian or an animal poison control service straight away — even if your dog seems fine.

The full answer

The ASPCA lists grapefruit as containing essential oils and psoralens, with vomiting, diarrhoea, low mood and possible skin irritation as clinical signs. It notes that the fruit is edible, and that the skins and plant material are what cause problems.

The American Kennel Club and PetMD both describe the flesh as not toxic, but advise against feeding it. Grapefruit is very high in citric acid and can irritate a dog's gut, and it offers a dog nothing that a balanced diet does not already provide.

We rate grapefruit AVOID because it is highly acidic, is not useful as a dog treat, and the peel and plant oils add extra concerns. Oranges are different: their flesh can be offered in small amounts, which is why they are rated LIMIT.

Grapefruit juice and grapefruit seed extract are not assessed on this page.

Risks and Things to Know

  • Acidic flesh can irritate the stomach and cause vomiting or diarrhoea.
  • The peel, rind and seeds contain essential oils and psoralens.
  • Tough peel can cause a blockage if swallowed in large pieces.

How Much Can Dogs Eat?

How Should I Prepare It?

  • Grapefruit has no recommended preparation for dogs.
  • If you want to share citrus, see our oranges page.

What If My Dog Ate Too Much?

If your dog licked or ate a small piece of grapefruit flesh and is acting normally, watch for stomach upset.

Contact a vet if your dog ate peel, rind or seeds, ate a large amount, or shows repeated vomiting, diarrhoea, drooling, low mood or skin irritation.

Oranges

Orange flesh is not poisonous to dogs, and a segment or two is tolerated by some dogs. But oranges are acidic and sugary, the peel is difficult to digest and can cause a blockage, and plenty of dogs simply dislike citrus. This one is a small, optional treat rather than a recommended food.
