Wisdom Panel Test Results Explained

The new 4.0 has 6 individual tests in which to evaluate the dog, giving us more information to make a better analysis of whether we have a purebred or not. We take into consideration each test result and evaluate a dogs purity based on those results. Your dog may show inconclusive on one test and still be a purebred dog. For help contact

Biewer Terrier Registry Information Registry for Biewer Terrier puppies

The Biewer Terrier Registry of America was established by the founding officers of the BTCA to maintain a reliable, accurate data base for the verification and registration of purebred Biewer Terrier dogs and puppies in America.  In order to have and maintain a respectable registry, free of political complications we have opted to use an established independent firm to hold and maintain all records and pedigrees.

We are passionate about building a solid foundation for the advancement and betterment of the Biewer Terrier. For this reason all breeders submitting an application to BTRA for registration of their Biewer Terrier shall be deemed thereby to have read and agreed to be bound by the BTCA code of ethics and By-Laws. This code of conduct and the By-Laws will be used to evaluate a person's right to register their dogs/puppies with BTRA.  Although it is not a requirement to be a member of the BTCA to register your dogs, we are welcoming of all breeders that are interested in the betterment of the Biewer Terrier.

Our goal is to give our breeders better tools to help them create superior Biewer Terrier Puppies.... the best in health, temperament, structure, and overall quality. Achieving this goal will result in those wishing to add a Biewer Terrier to their lives, having a greater chance of receiving a Biewer Terrier Puppy that will live to be a ripe old age and free from long term health issues. 

For more in information please visit the the Biewer Terrier Registry of America website. You will also find detailed explanations of the registration rules and how they apply to the AKC rules.

If you do not have a BTRA registered Biewer and  wish to register with BTRA, you will have to submit to the following guidelines to see if your dog is a purebred Biewer Terrier.  Because of the registering of splitters and mix breeds by various registries, plus the lack of DNA profiling, we have had to require a testing procedure to protect the integrity and purity of the purebred Biewer Terrier.

All non-BTRA registered dogs must undergo the Wisdom Panel cheek swab test 4.0 for registration consideration. This test can only be purchased at the Wisdom Panel website:
With the new 4.0, coat color analysis is provided, so it is no longer necessary to do one with DDC.

When doing the breed detection we would like to recommend doing the health testing as Wisdom Health has partnered with Genoscoper Laboratories. When ordering the two together the health test is only an additional $65.00. Wisdom Health, along with Genoscoper Laboratories, have just published in PLOS Genetics the largest ever study of its kind – “Frequency and distribution of 152 genetic disease variants in over 100,000 mixed breed and purebred dogs.”

There are now 4 components to the test; 1)Ancestry Chart, 2)Single breed PCA test, 3)All breed PCA test, 4)Next closest breed PCA test, 5)Pairwise overall test, 6)Homozygosity. You are allowed 2 "inconclusive" findings out of the 6 and will still be a purebred Biewer Terrier. The new web-site results are only showing 4 of the tests, but upon request the PCA charts can be requested if necessary.

Make sure you have your results reviewed before dismissing your new dog. If you have results that state your dog is 25% or 37% Yorkie it may still pass. A dog that is 50% Biewer Terrier and 50% Yorkie or any other breed will fail and not be allowed registration.

Once you receive your Wisdom Panel/Mars results and you meet the qualifications of the BTRA stating you have a “Purebred Biewer Terrier” you must get a DNA profile done with DDC. Click here "DDC" to go directly to the DDC site.  You will need to have a DNA profile done as we require DNA profiling on all breeding dogs.  Having a DNA profile is also a great identifier in case you lose your dog and need to have a positive form of identification.

DDC phone# is 1-800-625-0874

Explanation of the three generation rule for AKC advancement

AKC has supplied the following graph defining the 3 generation rule for advancement to Misc.

Explaining the 3 generation rule

The Wisdom Panel has 4 separate tests that are considered when determining the purebred status of a dog. Because of the genetics behind the test, BTRA acknowledges the purity of a dog if it passes 3 of those 4 tests. If there is an inconclusive on 2 of the tests, contact BTRA for instructions to request more results.
BTRA registrations will be listing the registration numbers assigned each dog in the pedigree if it has been deemed 100% purebred Biewer Terrier. Mars has provided the "Proof of Parentage" for each dog.

Explaining the 3 generation rule

The following graph represents a pedigree with DDC DNA and MMI/Neogen DNA profiling on all dogs. If you contact Neogen and ask for a certified statement, verifying the parentage of all dogs listed in the pedigree, you will get all the registration numbers, giving the dog a 3 generation pedigree.

Explaining the 3 generation rule

If there is an “inconclusive” on the Ancestry Chart, only the Biewer Terrier tested will get a registration number. If there is a Yorkie pictured in one of the generations, No registration numbers will be listed on any dog in that line. This does not mean that a Yorkie was used in the breeding of a dog, just that every so often, a shadow of a some DNA may show similar qualities. BTRA will use that information as meaning that Mars cannot verify the parentage on that dog.

Explaining the 3 generation rule

***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***
