Well, as most of you know I'm going to be getting a German Shepherd Dog puppy in about six weeks! Anyway, I was a bit concerned. I have a good friend who has a full-grown German Shepherd. My friend and I were playing with him and I had a tennis ball I threw it, and like the great dog he is, he caught it . The thing is, the whole ball (the WHOLE ball) fit in his mouth. I got so scared... I thought he was gonna swallow it. I ran and took it out of his mouth. The same thing happened with a baseball . I dunno what to do when I get my dog... should I let him play with tennis balls and such. I know he can when he's just a pup cause his mouth isn't big enough to fit a ball inside but when he's full grown is what I'm worried about. Any suggestions? Thanks.
