What a little sweetheart and congratulations on being named DOTD! It sounds like you keep your retired owners busy and that is good! I'm impressed that they would get a puppy because pups are so active.
My husband has been retired for 11 years and I have been retired for 5 and right now we have a retired service dog that we adopted from the Harrisburg,PA Susquehanna Service Dogs Association. She is not that active but does goes for walks.

Right now we are keeping a little dog just like Molly for a friend that is giong through a stem cell transplant and is in the hospital. Peanut is a minature toy just like Molly but she is seven years old and still is a little active.

I hope you and Molly have many fun years together.
