Well, that's another good way to put a Border Collie to work, LoL.
My Gryphon is the only German Shepherd I've ever seen who doesn't retrieve on command.
However, he LOVES to play with things like soccer balls and footballs and will chase them all over the place using his nose and his paws.
The problems arise when I have to replace a couple of kid-sized balls a season because I can't get the kids to quit kicking the darned things in my dog's direction
