More: Harley is a great dog. . We got him at 9 weeks old and he was 6.4 pounds. He is now 70+ pounds. He is so smart. It only took me a matter of days when he was 2 months old to teach him sit, stay, down, give paw, etc. We foster for a great rescue and Harley has not met a dog he didn't like. I cannot imagine my life without him.
