Gus is mostly sweet. He loves to play, and walks well on a leash when using a prong collar. He knows basic commands: sit, down, place, heel, here. He went to obedience training boot camp. However, he needs discipline that we can't give him in our home. He has bitten my daughter twice. With consistent strict discipline, he would do very well. He has allergies and has had knee surgery and will likely need knee surgery on his other knee in the future. We love him so much, but we cannot keep him, because we can't provide him the proper environment.
