Grandma is an elderly German Shepherd. We adopted her form a shelter as a hospice dog. She weighed 38 pounds (had actually gained weight at the pound) and was shaking when she walked. Now she runs all over the farm and helps with the horseback riding lessons. She is still thin, but is very active. When she heads off down the path, she is usually in the lead and barks to say hurry up. Oh yes she hunts squirrels now.
