Can Dogs Eat Star fruit?

AVOID

NOT RECOMMENDED — Star fruit is best avoided because some types contain dangerous soluble oxalate.

Sour star fruit can cause serious toxicity. Sweet star fruit has much less oxalate, but you can't always tell which you have, and kidney health changes the risk.

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

See our guide to common toxic foods for dogs for the wider picture.

The full answer

Star fruit (carambola, Averrhoa carambola) contains soluble oxalate. Sour star fruit can contain it in dangerous concentrations, and serious toxicity can occur.

Sweet star fruit contains very little soluble oxalate and, according to Pet Poison Helpline, is not poisonous to pets with healthy kidneys.

We rate star fruit AVOID rather than TOXIC because the risk depends on the variety and the dog's kidney health — and since you often can't know the variety, oxalate level or a dog's kidney status, we recommend not feeding it.

Risks and Things to Know

  • Reported signs include digestive upset, weakness and trembling, low blood calcium and kidney injury.
  • Dogs with kidney problems are at greater risk.

How Much Can Dogs Eat?

Do not feed star fruit.

What If My Dog Ate Too Much?

If your dog has eaten star fruit, especially a sour type, or has kidney disease, contact a veterinarian promptly. If your dog shows weakness or trembling, contact a veterinarian or an emergency veterinary clinic straight away.

Rhubarb

The part of rhubarb people eat, the stalk, contains very little soluble oxalate and is not considered toxic. The leaves are the dangerous part: they contain much higher levels of soluble oxalates. Rhubarb is still not an ideal routine treat, and sweetened pies and crumbles are not the same as plain stalks.

Grapes

Grapes, raisins, sultanas and Zante currants have been associated with kidney failure in dogs. The effect is unpredictable and no safe amount has been established — contact a vet if your dog eats any.

Kiwi

Kiwi flesh is not considered toxic to dogs. Peel it, cut it into small pieces and keep the portion small — the skin is tough and a whole kiwi is a choking hazard.
