I havent done any of these tests. This breeding is from PROVEN bloodlines with NO past problems. Careful and select breedings will result in production of Quality offspring. I believe these pups are just that. I bred 10 generations of bluetick coonhounds with many generations of top Trail and HARD TREEDOGS and 10 generations of beagles with top rabbit running beagles. The same way i breed my Labs. I have been fortunate to never had a problem and produced very great offspring. My CREEKPAUM'S BLACK PENNY (1988-1999) was a top Labrador Retriever. Penny would retriever a Duck or Canada Goose WITH STYLE I miss her every season.
