I'm looking for some games or ways/ideas I can play with my 11 month old pup inside. We have 1 puzzle, and he has toys. The games need to be low key since I'm working on a nipping/biting problem with him when he gets excited. I really don't see a lot on the internet so am wandering how other GSD's get entertained inside. Thanks for all the feedback. As always, it is greatly appreciated!
