A question occured to my mind as I was reading all the birthday posts. What are you experienced Shelties people seeing for lifespans? Not to be morbid, and generally not a topic I like talking about because our dogs should live forever. But in private practice, Shelties tend to do pretty well compared to similar sized breeds where 12yrs is avg. The shelties I've seen about 14yrs(all types of owners) I just realized that Justice's mom turns 12yrs in a month and that the entire litter(of 4)is still alive and doing great. His great grandpa(Ember and Diva's great great grandpa) lived to 17.5yrs(passed from heart disease-sudden), his grandma to 16yrs(passed of kidney disease) and his grandpa is still alive at 15yrs doing great but deaf. I hope my dogs do as well. J turns 8 next month so I realized he is offically a senior according to all registries for performance events.
