My mom had a yorkie named Mischa that was 17 years old...but sadly he passed away. I guess his little body just pooped out. His mind was as sharp as a tack until the end tho! Strange thing is that he came from a puppy mill,had all kinds of medical problems throughout his long, long life. Once he ate my uncle's blood pressure medicine and had to have his tummy pumped and was in a coma for a day and a half! He ate canned Alpo his whole life and he had all but two of his teeth left! Unbelievably he survived against all the odds! He's been gone 11 years and we still miss him everyday! He was a HOOT!
