hi, doberman puppies are definitely clutzy and can have boo boos here and there especially if they play rough outside. Puppies can also get what's called puppy pyoderma, I believe it's called. It's a mild staph infection. Does he have any lesions on his belly area or inside his legs? This is a common area for pyoderma. If it is a concern, it wouldn't hurt to have him checked out
