Paw Print Genetics offers inherited disease testing that screens for 15 known mutations in the Labrador Retriever. Included are some of the biggest concerns for Labrador owners: exercise-induced collapse, degenerative myelopathy, centronuclear myopathy and two types of progressive retinal atrophy.
See the full list of tests below.

With the potentially large number of diseases that have been associated in Labradors, Paw Print Genetics doesn’t want cost to be the reason you decide not to test. This is why they discount the price of their tests with each additional test ordered in the same dog. The more tests ordered, the greater the discount per dog. Order the tests you want or order the whole panel; the 12 test Labrador Retriever panel is the best value at $380.04 US dollars.
