My last yorkie passed away at 13 years old. She had a rough start in life and I am convinced that if I had her she from the time she was a puppy she would of lived longer.
Her previous owners did not take care of her at all. By the time I got her she had so many health issues. They never took her to the vet and I had to get all of her teeth extracted.
I still miss her and think about her everyday.
