Abby weighs 2.8 lbs. and is healthy and a little over 2 yrs. She does have LP that the vet said is not a problem, but i wonder if it will become a problem down the road. I do worry about her, but I probably would worry whatever weight she was, just because I don't ever want anything to happen to her. My sister-in-law's yorkie lived to be 16 at a little less than 2 1/2 lbs, so I am encouraged by that!
