Grapes, raisins or tamarind

Weight- and amount-dependent kidney risk

Documented data setNot every dog becomes ill after a few grapes, but weight, amount and product type are needed before the risk can be assessed safely.

Tartaric-acid content varies. The Merck Veterinary Manual gives more than one grape or raisin per 4.5 kg body weight as a general risk guide; this is not a guaranteed safe threshold. Raisins are more concentrated. Early signs may include vomiting, diarrhoea and lethargy.

What now?

Call a veterinarian or emergency clinic now with the dog's weight, number eaten, fresh or dried form and time. They can decide whether monitoring is enough or early treatment is needed. Do not induce vomiting yourself.
