there isn't much that I know of. Try to limit jumping from high places. It isnt good for the legs. Just feed a good quality food, no extra vitamins or anything. Dogs with bowed legs, can life great lives. We have a pound puppy mutt that boards with us. His legs are so bowed that his knees actually touch. he has never needed anything, and is in great health.
As long has your dog is living normal, active life, and is not in any pain. I wouldn't worry at all about his legs. Heck it gives him personality.
PM me and maybe send me a picture, but bowed legs and puppies can be a nutritional deficiency that is easily corrected in a few days. I am not saying this is what is the problem in your puppies, but it could be the problem.
I have seen a friend's Boxer puppies VERY down on their feet-- as in walking on their ankles, and very bowed legs. They switched foods, gave them more exercise and they were normal with in less than 2 weeks.
People need to find better vets.
