How much in Doggy Years?

In people years it takes about three minutes (in the winter when there is snow to negotiate) to take garbage out to the garbage bin and then roll the bin to the street for pick up. How much time in doggy years? Long enough to eat a three pound fruitcake. Minus one tiny slice.

Yup, dad got his fruitcake, my sister and her husband got theirs, my customer's got theirs but mine...mine was pelicanned down by the dog (or possibly dogs, but I think the little one is innocent this time) when I took the garbage out on the morning of Christmas eve. So no comments from you lot should I decided to get rid of the dogs. Instead I will expect murmurs of kind understanding.
