The BTCA, Inc., Biewer Terrier Club of America, Inc. has been named the parent club for the Biewer Terrier by the AKC. As the Biewer Terrier is gaining recognition World Wide as a breed of its own, the BTCA continues to assist those countries needing help in obtaining recognition with their respective kennel clubs. You can register your purebred Biewer Terrier with AKC/FSS, UKC and BTRA in the United States. We are looking forward to developing a strong, healthy foundation for the Biewer Terrier. For more information, visit our registry page.


The Biewer Terrier Registry of America has set the rules for acceptance using the 4.0 Mars test. This test is only available on line at www.wisdompanel.com/wisdom-panel-4-0/. The test has been updated and is actually 7 tests in one making it easier for us to make a decision on accepting the new applicants. BTRA has always been very conscientious of the registration of purebred Biewer Terriers and didn't want to see any dog excluded that was a Biewer Terrier. The following guidelines are used in determining the acceptance of an applicant.

Test “1” is an example of what is acceptable.

First part of the test is a family tree. There is a Yorkie present in one branch of the tree.

You can see the tree has four branches. Two branches from the Mother side and Two branches from the Father side.

The left side does not necessarily represent the fathers’ side, likewise the right side representing the mothers’ side.
Test 1 Family Tree
In order to save confusion in making judgment calls, we are defining the dog as the center portion of the plus. The black dot covers the center half of the “PLUS SIGN”.

These are the next test involved in the Mars results. In tests 2 and 3, this dog clearly matching the results of a purebred Biewer Terrier. The dog is inside both of the circles, clustering with the Biewer Terrier.
Test 1 results for test 2 and 3
Tests 4 and 5 are further indicators that the dog is a purebred Biewer Terrier. Test 1 Results for tests 4 and 5
The last test is a Pairwise comparison and this dog has passed with no reservation. It has been declared a purebred Biewer Terrier. Test 1 Results of the Pairwise Comparison

***Mars testing can now be done with a cheek swab through the Wisdom Panel website. The "Cheek Swab Kit 4.0" is the only acceptable test for the Biewer Terrier***
