Where to Find Testing

DNA testing is available through a variety of companies. As you can see in the table below, not all companies test for every disease. Sometimes a combination of testing is required. The Top Row shows the name of the company where you can order and send in your tests. See below the table for links to each company website. It is also important to note that these companies test for more conditions than that are listed below that may not be applicable to Border Collies.

DNA Terminology

Normal/Clear: 2 normal copies of the gene. The dog is free of the disease and does not carry the gene that will produce the disease

Carrier: 1 positive copy and 1 normal copy of the gene. The dog does not have the disease but can pass the gene to its progeny. A carrier should be bred only to a dog that is normal/clear

At Risk/Affected: 2 positive copies of the gene. A dog that is at risk/affected will have or develop the disease in its lifetime

*Clear by Parentage: both parents have been DNA tested clear for the disease. This should be proven to puppy buyers with documentation of the DNA test results of both parents
