Hi! This is Lilly and Ein's mommy. Ein is my old boy of 12, red headed pembroke. Other than orthapedic problems (birth defect, clubbed leg), and how overweight he was when I adopted him (2003) - he's pretty healthy. My Lilly is only 3, a cardi mix. She has cutaneous lymphoma, which is not typical of the breed, not to mention her age. I think the breeder was pretty spot on as far as how old we can expect our furry little children to become. :) I just lost my English Springer Spaniel a little over a year ago, she was 14. I am still greiving her loss, but she had a great life.
Pedegree.com has a chart that shows life expectancy of each breed, and how old each breed is in human years at every age. It's very interesting. Corgis are high end on life expectancy, and have puppy phase for a long time. I don't know how good the science is, but it's fun to look at.
