King has been with us since he was a few weeks old. He is a very sweet, gentle, calm dog. In his older age he has settled down a lot and will be happy 1 30 minute walk a day or a couple shorter ones. He is well mannered in the house and on leash. He is ecollar trained and pronged collar trained. He has been professionally trained throughout his life. The only Issue is his dog aggression. With the proper handling on a leash his reactivity is minimal but he is very dog aggressive if off leash or in very close proximity. Otherwise he is the best dog and i hate that I need to make this decision, he deserves a loving home for his last few years of life.
