About 3 weeks ago, I adopted a beagle who is about a year and a half. His name is Louie. He is very timid and scared of everything. He wouldn't eat at first and he still won't accept treats. In the past week, he started being destructive, tearing up my carpet and digging at my hardwood. I have no idea what kind of training he has (if any). I really don't want to crate him while I'm at work and at night, that's just too much! I thought about getting him a friend since he has enjoyed every other dog he's met so far, but don't want to end up with 2 destroyers. Any advice on traininng a dog that doesn't accept treats and cowers when petted?
