Thank you all for your suggestions.
He was born in August, and when we got him he wasn't in great shape. His puppy hair was shiny but his skin was a mess and he was covered in fleas at 5 weeks.
Yes, I have checked w the Vet. So far its not medical so I was thinking it could be food or maybe baths once a week are too much? Idk. I try to wait longer than a week but believe it or not, He walks into the shower himself every chance he gets until I bathe him.
I'll try the fish oil.
I ignore what people say about his size. It really makes zero difference to me, he is the best dog in the world. I just hate how pushy and insistent they get. Like if you don't believe what he is that is fine but just shut up and move on. No, he doesn't look like a Schnauzer or anything else for that matter so just drop it. lol
