Try to find some handling classes in your area -- you can take your own dog there, show quality of not. It will give you experience and you are more than likely to find breeders there taking the classes to get their dogs used to a show situation. You can talk to them and see if they would be interested in letting you show their dogs. Alot of breeders appreciate having handlers under them -- it's useful if you are showing multiple dogs, or if you are showing multiple breeds and their ring times run into eachother (can't do two things at once!). You can also just email some breeders in your area, see if anyone is willing.
