Story
Charlie is a good dog he is smart just very strong and needs some training and someone that can spend time with him. He has lots of energy Loves going on walks. The problem is we just done have time to walk him like he needs and we just had a new baby so time is even more limited. He is 10 years old but has energy like a puppy. He has been well taken care of and we have had him since he was a puppy.
