Like he ate the whole couch, hurts himself in a wire crate chews a plastic crate. He is a rescue about 6 months old and lived at the shelter for several weeks before going into foster care. He only does this when his foster family is out of sight. They can still be in the house but in another room and he freaks. There are other dogs and cats in the home and he loves them but they don't curb his anxiety. Several strategies are being tried but do any of you have suggestions?
