One of the things I was struck by in once again listening to "Dog Years" is the lack of a mention of a breed. Since there is so much diversity in the breeds, and diversity in life spans for that matter, the song could take on a much different meaning if you think he had in mind a Great Dane vs say a Bichon Frise. So, TRF, which breed do YOU feel that Neil had in mind while composing the lyrics?
