My six month old berner, Digory, hops like a kangaroo. Like all the time. He literally gets up on his back legs and jumps with those, all four paws off the ground. And if he's not doing that he's leaping everywhere. It just seems like a giant puppy shouldn't be able to do that! And he ends up knocking so many things over just too excited for his own good, poor guy. Does anyone else see this behavior in their berners? Any tips for getting an excited puppy to keep his giant paws on the ground?
