Hola Everyone,

My friend has a 10 mo old Dane/AmStaff mix who is chewing up her house inside and out. She has tried bitter & hot flavored sprays but that makes him lick and chew all the more. She has tried leaving him outside in the yard when she's gone and he chews up the fence and the exterior of her house. She has tried a muzzle and he played and fell asleep comfortable in it and then chewed it off 10 minutes after he woke up. She tried crating him in a metal crate with the hard plastic tray bottom and he's chewed through the tray. He'll chew the drywall off and came close to getting to the electrical lines in the wall.

He does get a 30-60min walk a day and he has another dog to play with during the day. He has gone to basic training and does really well with that. She's tried everything I could think of - various toys, activities, extra exercise, muzzle, crating, and he's still going strong. This trial and error has been going on for months now and she is at a loss of what to do beyond continuing to fix her house and replace furniture and hoping he doesn't hurt himself.

I read in another post about a list of behaviorist in the DFW area. Any recommendations?
