No, I was simplifying. Crossing wolf into them gives a bad gene 50% chance to not be passed down.
Of course we don't kill pups with problems. We would neuter them. No passing it on. Fortunately, we have had no problems. Our wolfdogs come from healthy lines.
If a problem is apparent, it will be tested for. I'm sorry, but you don't seem to understand wolfdogs. They are not just xyz breed of dog, bred with a wolf. We have wolfdog parents and grandparents and great-grandparents STILL owned by their breeders (retired and happy by now), and we can see the health of the pedigree all the way back. Also, unlike breeding xyz breed, there is not a 'common breed problem' to test for. Wolfdogs are not predisposed to genetic problems with eyesight, or hip placement, or joint problems, or skin problems, or etc. There are hundreds of tests for problems divided between hundreds of breeds. You don't just say 'well you need to have your breeding dogs tested'. For *what*, exactly? NO breeder of ANY dog breed just 'screens for potential health defects' of ALL the possible problems that could be in each breed of dog. What you are pretty much saying is 'well my breed has xyz health problem a lot so why aren't you testing for it'.
If a wolfdog presents with a problem, it's tested. Then it's parents are tested, and it's offspring (if any), and if they have it, they are neutered. I'm sorry if you feel that we should test for things that have never cropped up in any related wolfdog at any time. Should I apologize for having known healthy lines?
