giving dogs vitimans. good or bad?

I bought some kind of vitimans from the store yesterday,( my friend used the same on his dobie and he grew like a weed!) my question is what can i do other than free feed and excersize the hell out of him so that i can build up his muscles, i dont want to weight train hm because i dont wanna hurt him. I have been running him alot and playing alot of tug of war with him and his hind end has grown to be rather musclar but i dont know how to build up his front legs so he dosent look so uneven. any help will be greatly appreciated.

 

How old is he? I would just feed him a high quality food and he will grow, just give him time. If he is real young, don't over do the exercise because of the strain on his young joints and hips. Also, genetics has a lot to do with it also.

 

Just like jay said...If he is very young do not make him over due it. Keep up the running! 8)
