Can Dogs Eat Grapes?
No — grapes are highly toxic to dogs. Even a small number of grapes can cause acute kidney failure. Seek veterinary care immediately.
Grapes can cause kidney failure in dogs
The exact toxic substance in grapes is still unknown, which means there's no safe amount. Some dogs are severely affected by just a few grapes while others show no symptoms — but you should never take the risk.
