Well, I also have a tiny...Roxi weighs 2 lbs, 15 oz (woohoo--she gained an ounce
) She is 1 year, 4 months. I also have the same concern as you, but with an added worry. Roxi has been diagnosed with MVD. My vet once made a comment about just enjoying her as long as we have her. That kind of upset me at the time because I felt she was implying that Roxi wouldn't live very long. But I have read posts on this board about other yorkies with MVD and living 15-17 years just by managing their diet and maybe with some supplements or prescriptions. I also would be interested in hearing how old some of the other "little ones" are.
