With CARA racing, I believe the rules state that mixed breeds and non-sighthound breeds can be entered in Non Regular races that are held by the host club. I know we have raced some pretty strange breeds. Last year we had poodles (not good at it) Am Eskimo's and what they are calling Mini Aussie's. So yes, we do try out other breeds at times. We generally hold practices when we can, either before or after the meets. We are pretty informal. We also generally have pot-luck so this tells you how informal we are. We race in a field that is contained for the most part (fencing with a gate) and most people generally know not to chase the dogs. You get the odd one person. We also have people who get Basenji's and their attitudes towards each other so we are alert on how to judge them as well. We had one person who judged a couple of years ago who wanted to disqualify on everything since 1) she didn't like Basenji's (although she complimented me on my temperments, she said all Basenji's she knew were nasty, but mine were never nasty and didn't snarl) and 2) she is no longer with us since she doesn't like that we allow long-haired whippets to race (whippets are her breed).
Lisa, I don't know if your Mom told you, but I used to, from the time they were very little, used to use a cat's fishing toy to play with them. I do have a 7ft buggy whip that I tie the rabbit's fur (or hot dog smelling bag) on and use it outside with them when it is warmer. Rose will probably race too, I tried her last year when it was warmer. We don't have very many meets, maybe three or four last year because of weather, scheduling, conflicts, etc. But we try to get out as often as we can, all things considered.
eeeefarm-if you go to a farm and feed store (like Minor's Bros) or a tack shop you should be able to find a buggy whip. Like I said, I started with a simple cat's fishing toy. It's something to try, and if you'd like to come to a meet, either keep an eye on the CARA site and Laurie will be updating it as soon as she knows when bookings start. Laurie is also starting a UKC Chapter here, (I believe this is just something that she is working on right now) so I'm sure she is going to be extra busy this year, or keep reminding me to let you know when we are meeting up.
