My puppy is only 3mo. and I'm not looking to start any time soon. Its just that I've seen some rottweiler's that have more muscle definition then others. I have seen pit bulls be trained with sleds and heavy chains. I've been told that the heavy chain builds the neck muscle and the sled for a full body work out.

My only purpose is to make him as strong and healthy as possible.
I've put a link to illustrate what I have seen. The third pict. of the rottweiler has a lot of muscle definition and while the rest not much.

Any suggestions would be great.
Thanks.
