It's difficult not knowing a puppy's past.
Sam obviously has trust issues and he's never been properly trained. There's so much work that's needed to get him to an adoptable state.
He has made tremendous progress these last 3 weeks though.
He's now housebroken and he's learned his name. His "mouthing" has decreased and we're working on his touch aversion.
He went for his first fun car ride and it seems he enjoyed it a lot!
