My 120 lb American Bully won’t eat his food

we adopted him like a year and a few months ago from a pretty rough situation. He’s a big guy 120 pounds so when he stopped eating a few months ago, we were all pretty concerned. With that said though, my father doesn’t think it’s serious. His hair has started to fall out and he’s getting this bumps of dry skin. We don’t know exactly how old he is so i’m worried that he’s just getting old and losing his appetite. My father thinks that he’s not eating because we have a puppy in the house too but he stopped eating way before we got the puppy so idek why he says that🤷‍♂️

anybody know what’s going on w him?
