My dad showed my dog for some time.(is that proper english?) Anyway-you can email me any specific questions you have & I'll try to point you in the right direction. There should be local dog clubs in your area that can get you started. There's also a "junior handler" type thing, but I'm not sure of the age limits for that. I'd say register with the AKC & you should get a newsletter about upcoming shows.

I'd love to help get you any other info, just let me know what you need!
