Can dogs have blackberries?

Yes – blackberries are generally safe for dogs when plain and fed in small handful-sized portions.

Why it is or is not safe

Most berries are not considered toxic. Too many can cause loose stool because of fiber and natural sugar.

How to serve

Serve washed, plain berries. Start with 1-2 berries for small dogs or a small handful for large dogs. Avoid sweetened or chocolate-covered berries.
