EJRTCA Breed Standards

The EJRTCA Breed Standard shall serve three purposes:

1. To set ideal, attainable goals for the breeder.
2. To guide the judge.
3. To guide buyers in finding correct or acceptable specimens of the breed.

In the registration process, the terrier, if accepted by the EJRTCA Registration Committee, will be assigned to one of these categories:

  • Advanced - The dog meets or exceeds all EJRTCA Breed Standards and processes a three-level pedigree -OR- has progressed from the "Tentative" category based on show and/or trial performance.
  • Tentative - The dog conforms to EJRTCA Breed Standards but does not process a three-level pedigree. Can progress to "Advanced" based on written application to the EJRTCA Registration Committee detailing accomplishments in show and or trial performance.
  • Pet Quality - Reserved for dogs which generally meet EJRTCA Breed Standards but are deemed not to be of breeding quality or which have been spayed or neutered. (Typically, might include dogs with severe over/underbite, dwarfism, exaggerated  shyness/aggressiveness, etc.)
