My puppy has white lumps on his belly and I want to know what it is. He hasn't been wanting to eat and he is very skinny and weak.

Hello. It is not uncommon for puppies to have minor skin infections due to their developing immune systems. Most just heal on their own, or often we may recommend a medicated shampoo. But if Sorullo has not eaten, is weak & skinny, there is something much more serious going on. He really needs to see a veterinarian at your earliest convenience. I hope he is feeling better soon & thanks for using Petco Pet Education Center, formerly Petcoach.
