My four yr old lab is having problems when my husband and I leave him. We use to gate him in the hallway with all of his stuff IE: bed, toys but when we would arrive home a few hours later (2-3 at the most) the gate was destroyed and our blinds were eaten. We then purchased him a crate and tried to start introducing it to while we were home for ten, twenty, thirty minutes at a time. We then after a week left the house for a few hours and place him in the crate with a TV on, his Kong toy and his blanket only to come home and find that he had tried to eat his crate door. The door was bent in and a piece of it was broken. Before we placed him in the crate we always take him outside for 30-40minutes to play ball and use the bathroom. Does anyone have any suggestions as to help him with what seems to be separation anxiety? I'm really concerned that he is going to hurt himself.
