Can dogs drink milk?

Caution

A little is usually fine, but many dogs can't digest it well.

Lots of dogs are somewhat lactose intolerant, so milk can cause gas and diarrhea.

How to share milk safely

A few laps at most. Plain unsweetened yogurt or lactose-free milk is easier on most dogs.

Why?

Puppies can digest milk, but many adult dogs make less of the enzyme that breaks down lactose.
