From my own research and interest in agility, I know Duke will have to have a good basic obedience with sit, stay, down, and definite recall while off leash for agility. At 18 months they can start the jumps, I believe. Vasha had given me a name of a group in our area -because I was interested in agility for my girls too. So, I definitely have time before Prue can go and Jazz definitely needs more OB work. I'll try to track down the web site for you. I'm thinking it is Dawgagility.com possibly. Try that and see.
In my past experience breeder's who show their own dogs have been more than willing to talk to me at shows when the are not busy. I think the professional trainers with a harem of different breeds are harder to talk to. I do know one of the most experienced professional boxer handlers in the nation lives here in Flower Mound!! My husband spoke with him briefly at the Ft. Worth Dog Show last year when he was busy. He was very polite and asked my husband to contact him after the dog show and told Steve that he was listed in the phonebook. That is while I was looking for Prue last Spring. I always try to spend one whole day at the Ft. Worth Dog Show in March.
We do have the Dallas Boxer Club. They didn't have a working web site last Spring but they may have one now. i found their officers throught the AKC web site. I also contacted them when I was looking for my boxer baby.
