How to verify your unique breeder prefix

This video shows ADCA Dexter Cattle breeders, how to search the breeder pedigree site for unique breeder prefix names. The breeder prefix must be unique to you and not being used by any other breeder.
The only way to secure your breeder prefix is to submit an application to register your first Dexter. Once that name is allowed, your prefix is fixed to your farm and membership number. Until you register a Dexter, using that name, anyone else can use it.
