Please don't take him to the pound!

Try a dog behaviorist if you can. Or talk to your vet about other options. Try the rescues, or if you know anyone who will take him and is willing to work with him. I wish you the best of luck with him. I recently went through a similar situation with my moms dog, she was about to put him to sleep, but a profesional trainer who evaluated him said "he's not at a stage where he needs to be put down" and that gave me soo much hope! I hope the best for you and your little guy!
