Frequently asked questions
How many grapes are toxic to a dog?
There is no proven safe amount. Because sensitivity varies a lot between dogs, any amount should be treated as a potential emergency.
Are raisins worse than grapes?
Raisins are dried grapes, so they are more concentrated. The same toxic risk applies, and raisins often hide in cookies, trail mix, and cereal.
