It must be heart breaking to see Malone so upset

I have never tried any of these things since we have never come across this problem. I have heard that the following things will help



Get ready to leave (get shoes on, cars keys ect) and then sit down on the couch and comfort Malone, make sure he is at ease and then leave. You should try leaving the house and saying things such as “I will be back soon”. Leave for thirty seconds and then come back. When you come in act normally and calm so that your dog will do the same thing and hopefully learn it is not that big of a deal. Everyday increase the time you are gone and make sure you start small. (go outside for like two miinuetes and come back in at first) Also make sure Malone has stuff to occupy himself with. for example, you could fill a kong with peanut butter.

I hope he gets over this. It will take time and if probaly will become very frustrating but make sure you keep workling with him
