I own dogs, chickens and horses. I am on a horse forum and we talk about HTTP which is a genetic disorder that occurs in horses descended from the QH Stallion, "Impressive." This was caused by deliberate inbreeding, breeding sire to daughter, son to dam, and their descendants to each other. The horses have seizures and die painful deaths. Perhaps bc horses are utilitarian, that is, we choose to own and ride or drive them, that the horse industry suffers from fewer genetic inbred health problems, but this is just one example and they do exists in other breeds as well. Horseman often cross between breeds and many horse breeds accept and register animals that are outcrossed.
The Thoroughbred industry does not do this. TB's have bad backs, poor legs, tissue paper hooves and many are raced into their ground and don't live to see their 10th b'day. Remember the filly, "Ruffian"?

She didn't live to see her 4th b'day. Her leg snapped in a race from poor build and directly related to inbred genetics.
When you have a problem that can be fixed by stopping bad behavior, like smoking, why do you choose to defend the bad behavior?
I have a grandson of Impressive. He is 25 years old, tested negative for HTTP as a colt. Hard to believe that people breed HTTP horses.
