There's LOTS of longhairs breeds: Peruvian, Sheltie, Coronet, Texel, Merino, then you can add satin to them -new breeds keep appearing all the time so I've lost track of some LOL. The longhairs are very hard to show as you have to keep the fur rolled up when not actually ON the judge's table -compare to Yorkshire terriers. The coat length can and should be around 50 cms. The advantage is that in longhair breeds colour is not judged so they can be any colour and any markings. :)
There's quite a lot of show preparation involved for most breeds, the smooth coats for instance need trimming (a bit like hand stripping) to get their show coat.
I think it's fair to say that in all the small fancies, it is generally breeders showing so each exhibitor tends to turn up with several entries. In cavies like in rabbits for instance you will have the entire class on the table at the same time, and cavies are put into little wooden boxes so they stay put. :)
