What Can I Give My Pitbull To Make Him Stronger?
A good balanced diet and a daily, progressively more challenging exercise routine. Assuming that you have a healthy dog with sound conformation. As with any athlete canine, human or anything else..... No magic, but a good pay off for hard work.
Well you could make it run around with you outside and feed it good food and not that food for five dollars try 20 dollars
