Breed Standard

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/under bite, dwarfism, exaggerated shyness/aggressiveness, etc.)

Color
Predominantly white with tan, black or brown markings. The tan markings can be from the lightest tan to the richest tan (chestnut). Ticked or mottled acceptable. Brindle not acceptable.

Faults
Any departure from the foregoing points should be considered a fault and the seriousness with which the fault should be regarded should be in exact proportion to its degree. However, the following weaknesses should be particularly penalized:

  1. Lack of true Terrier characteristics – Nervousness, cowardice, over-aggressiveness.
  2. Lack of balance, i.e. over exaggeration of any points.
  3. Sluggish or unsound movement.
  4. Faulty mouth, week bite, minor physical deformities.
