How big does a black lab get?

This really depends on alot of things. First, it depends on how well bred your dog is. If you got your Black Lab from a breeder than you can look at the mother and father and guess how big it will get. But, if your dog came from the pound (or rescue or humane society, etc....) as a puppy there is really no way to tell except, you can look at there paws. If the paws are big it is going to be a godd sized dog but if the paws are little than it is not going to get that big. Also, it depends on what your dog is fed and how it is kept.
