I would definitely wait a year before the running. You want to let your puppies bone plates solidify before you have him/her start pounding the pavement.

Please accept my condolences on the passing of Nubia and Ramses. But what a beautiful story about how Leeloo has come into your life. To me, Leeloo coming into your life is not a coincidence. Often there are plans for us that we never understand fully why, but they happen. May you have many many years of joy with your Leeloo. The pictures are wonderful!
