In the 4 days I've had him back he has picked up the routine quickly. He is house broken and uses the dog door to let himself out without any problems. He sleeps on my bedroom floor all night and does not bother me until I wake up. He still needs supervision as he is still a puppy and has that puppy interest in anything new.
He has no issues with other dogs big or small. He and Cindy-Lou play all day and then crash at night.
