Can dogs have milk

Depends on your dog. Once a dog is past the puppy stage and finished feeding from it's mother or bottle fed, then milk can be eliminated from the dogs diet. Milk can cause diarrhea in many adult dogs because as the puppy grows into adulthood it looses some of it's ability to digest lactose. How much ability is lost depends on the dog. To see if or how much your dog can tolerate, give the dog milk in small quantities. Once you see your dog can't tolerate a certain quantity, back down on the amount or a better solution is to give the dog lactose free milk in place of regular milk.
