Hey,
One of my yorkies is 8 years old and a bit chubby. She has short legs compared to my other one who looks like a race horse next to her! We have been feeding her Nutro for overweight dogs- 3x a day about 1/4 of a cup at a time. We haven't noticed much of a difference. She swims like crazy in the summer in our pool. She is healthy, though. We don't feed her any table food at all- our other yorkie suffers from pancreatitis so we are real careful. try the Nutro- she seems to like it! By the way- my maiden name is Freese - are u originally from NY?
