Sounds like separation anxiety!
I would start by doing little things.. such as when you leave -DO NOT say goodbye to him, don't make eye contact, don't make it a big deal. Just walk out the door. No bye byes, no "be a good boy," nothing! Same deal with when you get home... you can say hi but don't acknowledge him until he's in a calmer state of mind. He's probably very anxious and nervous and thinks you may not be coming back. How old is he? And how old was he when you got him? Being taken away from his mom/litter mates can cause this sometimes. It's a scary time in a pups life and you are ALL he has in his mind. You are his everything.
Try this little routine training exercise where you pick up your keys, your purse, etc, but DON'T walk out the door. All the things you do when you normally leave - putting shoes on, purse, keys as I said, jingle them around, let him know that you doing those things doesn't necessarily mean you are leaving. Get him used to those things. Walk out the front door for 5 secs, come right back in but don't acknowledge him, just act totally natural and walk by, then do again... walk outside the door for 10 secs now, walk by him calmly and naturally again. It will take some practice!
The biting, chewing, peeing, pooping, etc could just be him lashing out built-up energy! How much exercise does he get during the day? Try to take him for a good long walk before you leave the house. It will tire him out majorly and make him just sleep the whole time you are gone! |
