What is the JRT Health Registry?

Submit your Jack Russell Terrier and test results to the JRT Health Registry.

Testing Forms

Genetic testing forms can be found in the Forms Library.

Normal By Descent (NBD)

When a dog tests Normal it means he is carrying two normal copies of the gene in question, therefore he can only pass on a normal copy. When two normal tested dogs are bred their off-spring will also carry two normal copies, hence the term NBD.

However there’s one important aspect being forgotten. This rule only holds true if you are using gene based testing. If you use marker tests or linkage tests you must test every generation. This is why AKC and OFA will only certify first generation NBD’s from gene based testing and WILL NOT certify NBD’s from marker and linkage testing.
