The dog is probably a little confused with new surroundings, and his new owner. I have had a wonderful vet, through three dachshunds, and that is no easy task, lol. Dr. Youngs first and foremost principle with dogs is that they need to understand, for their sake, who is the dominant. That would be the owner. When you feel comfortable with Buford that he does not bite and you need his attention to learn........get on the floor, gently roll him on his back, get on top of him, disable his movement, gain eye contact and his attention and don’t look away. When he stops resisting and looks away, pet him and give him a good boy and let him up. Training will start to be much easier at that point and after a few of these moments he will forever be yours.
No offense Toespi, but this dog could very well panic if alfa rolled and CSM could be hurt.
Do NOT roll an adult dog you’re bonding with!!!!
