My baby Pitbull/bulldog has these odd missing patch of hairs I see him bite and scratch himself but not crazy but it does happen. So by looking at this is it severe is there anything I can do to stop this I want his beautiful cost to stay beautiful lol. Also, he's 4 months and 40lbs mother is 50lbs father is 70lbs. How much do you think he'll weigh full grown ?
Mom was Pitbull
Father was American bulldog
Btw I give him omega 3, salmon oil, and a multi vitamin
