Think people sometimes do not realise that Special classes are special to the club or society staging the show. There are no set rules for special classes, the club or society will decide on what the rules for that class are.
Some shows will have several Special classes the most common are:
Special Veteran
Special Beginner
Special Yearling
and then you have the colour classes that are limited to one colour and pattern of colour:
Ruby
Tri
Long
Smooth, etc
also classes special to the group or society:
Special racing,
Special coursing
Special working
Special sighthound
Special scenthound, etc
Sometimes there are special memorial classes or classes only open to members or founder members
All of the above will have there own conditions for entry and may differ from show to show, so before entering it is important that you check in the schedule to see what the rules for the class at any particular show is. I.e. Special Coursing could be limited to Greyhound, Deerhound, Whippets or could include all or any breed.
