I don't know, My Ginger that I lost this summer was 15 years old. She was only 4.3 lbs and was a very healthy little thing for many years. She only started having problems the last couple years, which were natural for her age. She did have tooth problems but that's common for yorkies. I now have a little girl that is 7 mos old and only 2.4 lbs. She is very healthy and although she had to have her baby teeth pulled because they didn't come out. Also common among toys. I diagree with the common talk around here about tiny's not being healthy. I have known other small yorkies and they were also very robust and have lived long good lives.
