Dogs...

While walking in the city I stopped a dog on his walk with their people. It was one of those mixes, smaller dog. I asked about the dogs age and they said 13. I said that the dog was spry. I wonder if dogs hate hearing that as they think of their canine legacy and how their people would either lose it or move on and get another dog. Do they look back in regret on an eggplant in the trash not eaten on a christmas morning or wish they did not spend so much time barking for no reason?
Also saw a swiss mountain dog.
