We should all dig deeper. I was thinking it was genetic in nature for starters but don't know for sure. I know that wolves, especially the alphas tend to live 12 years or longer barring any accidents or diseases. They are large dogs, but are also very social. As our Yorkies (and other breeds) were downsized and or bred for special purposes like retrieving, guarding, pointing, herding, etc. something was compromised. Maybe their stress levels went up. Smaller dogs are more pampered so their stress levels are down. (I am reaching here, folks). All this as they got away from the "wolf".
Whadya think?
