Rescuers describe this purebred Pomeranian as energetic, eager to fetch a tennis ball or play with children. Max is estimated to be 7 to 9 years old and weighs 15 to 20 pounds. He knows basic commands and wants to please, but he does not get along with cats. He needs regular grooming to prevent matting. Animal Rescue of Tracy is a nonprofit, all-volunteer rescue group that has adoption fairs from 11 a.m. to 4 p.m. Saturdays and noon to 4 p.m. Sundays at the West Valley Mall.
