I am boarding a 8 month old Husky starting last night. He isn't trained at all, and then this morning he was chewing on a shoe and I tried to get it away from him and he bit me, hard enough to break the skin. I messaged the owner, who speaks English as a second language, but basically he was saying oh he does that sometimes, he's just nervous, put him in the crate. But the dog is now very defensive of his space (I have him in one area of the apartment because he kept bothering and trying to hump my dogs, plus getting into everything and chewing on everything)

I know he's just scared in a new environment and doesn't have any kind of training....

What do I do?
