Little Bear the Jack Chi at 2 years old riding on a motorcycle—"This is my buddy. He is very smart and very friendly to all from infant to adult (once introduced ) and he dearly loves riding on the motorcycle. He doesn't even mind wearing his doggles. When I lost my wife I was not looking for anything to take care of. I was asked to "hold him for a second" when he was 2 weeks old he kissed my nose and peed in my hand. By the time I stopped laughing ... he had me. I only wish everyone could find a friend like like little bear."
