Oh my Emily.I am so sorry.Do you have a behaviorist that you can contact that could help.Sometimes trainers,vets or people like that can help you find a behaviorist.I have found great help from them.They have different training and can help in special behavior problems like this.This is hard to help in cyber space but maybe while you are waiting for help you could give him a kong filled with special goodies when you get home in a space away from you while he settles down and realizes that you are home instead of him tearing you up,maybe Abbeys pen, without her if they will fight over the kong, anything to calm him while you come home.Oh how I wish I could give you a quick fix.I am so sorry I can't > I am sorry
