How Old Is Your Yorkie?
Dogs age much differently, the largest factor being their size. Therefore, the Yorkie, being a small breed dog, will have their own timetable of aging. A good point to remember is that just like humans, as time goes on medical discoveries allows the canine to live longer. Back in the 1920's a dog generally lived 7 human years. Now, the Yorkie's life span is generally 12 to 15 years and many Yorkies live even longer.
