I just wanted to let you know Diablo and our puppy Bella have hit it off big time. From tug of war contests, to racing around the yard and joint nap time, the 2 of them are doing great. He has been a great addition to our family and is really helping us out with puppy training. We have been working on leash training with both dogs this week and having a second dog to learn from has sped up the process considerably.
