Carl is a sweet cuddly couch potato who plays well with other dogs but would also be perfectly content being the only pet.  His energy level is quite low and only requires a short walk a few times a day.  Does great on leash until he's tired and doesn't want to walk anymore.  He is doing great with potty training but like most rescue pups if left unattended he may have an accident.  So I would recommend crating which he is perfectly content hanging out in.  He also loves to chew on dog bones which are great for keeping his teeth clean.
