I have a beautiful blue merle male, 6 years old. He needs so much more than we can offer him. We are retired and cannot keep up with him. He is afraid of smaller children and I can't trust him with them. He is also afraid of puppies and unsure around some men. He is very loving, especially with women. He just has more energy than most people can handle. He walks well on leash and is housebroken, but he will mark in unfamiliar surroundings. He loves being outside.
