Estimated Reading Time: 1 min | Last Updated: June 26th, 2018

Dogs cannot eat grapes even in small amounts

Grapes, sultanas and raisins are very toxic to dogs although the exact cause of the toxic reaction is not known. Ingesting these sweet substances can be fatal for dogs of any age, breed or gender. This includes when used as an ingredient in Fruit Cakes, muffins or Hot Cross Buns.

Cats are least likely to eat grapes or raisins and there are no reports of cats experiencing toxicity from these foods. However dogs can suffer acute kidney failure, so it’s best not to take the risk if you think your cat has ingested these fruits. Seek veterinary advice to ensure all is well in any case.

Emergency treatment before transport to a veterinarian

PVE does not recommend any form of emergency treatment prior to transport to a veterinarian. If you suspect your dog has ingested grapes or raisins, you need to seek veterinary help as soon as possible even if they are not showing symptoms.
