Ok. I've been thinking of some ideas to help build a bit more muscle on Byeboer, he's still a growing dog and i don't want to comporomise his growth or health in any way. He goes for a mile jog with me every other day and i've let him pull around a chain a few times. We also play tug and he's working pretty hard on obediance right now. I do feed a suppliment called NuVet Plus, Its awsome and has shown alot of improvement already. Basically I think he's getting bored, Any ideas oh what we can do to add a bit more musle and tone?? Something safe, yet fun for him at the same time.
