"In an exchange with Kate Meurs she shared there are fewer genes in dogs than in humans. She did not give an indication of how many. I am working toward all my dogs being tested. Stud dogs results, if they have been done, are shared on my web site. Logic tells me that even though the test is new, all of us, especially long time breeders, will have had positive dogs in the past; they just were not known. Holters and Dopplers still being the definitive testing IMO while working towards ARVC-1 & ARVC-2 Negative. The breed could be in a precarious position, given we have no idea what percentage of dogs will test Heterogygous and Homozygous. If based on this gene test alone dogs are eliminated from our gene pool or those with negative dogs will not breed to Heterozygous or Homozygous dogs, with excellent Dopplers and Holters and longevity in their pedigree long term effects on the breed could be disasterous. When we know better we hopefully do better. The path is not abundantly clear at this time IMO."     Cheryl Cates, Well Respected Breeder
