I get that too when asked about their ages. It seems that many mid-sized dogs we know have passed away at around 10-12 years
I know that Siberians have a life expectancy of 12-15 years but I don't think Timber is a pure breed and Shiloh, not sure if she is part hound or has some lab or shepherd??? I do feel lucky to still have our girls and always hope they'll get close to reaching the world record of 29 years! Amazing! There are even a few larger dogs on this list! I wonder what they are being fed?
Not sure how accurate this is but I found this list of the oldest dogs on wikipedia
