Study: Most Dog Breeds Highly Inbred

This is interesting, but not exactly news. Has been known for decades.

Going on 30 years, I have had a pack of working hounds, usually from 4 to 12 strong. We have rural land surrounded by large plots of more rural land, 4,000 acres+ of tree farm and private hunting preserve, so our hounds are necessary for keeping coyotes and etc off livestock and other pets.

In that time we've had many litters of puppies, usually trading them with neighbors to improve the local landrace and pass around some of the best traits. There's a steady input of "dumped purebeed" in the local mutts, they never survive long unless rescued.

"Pure" breeds are useful in being controlled and defined parameters to breed from; hybrids are the best "working" dogs however. IMO.

Our greatest successes have been with hunting hounds (bluetick coonhound or great danes) x "herding dogs" of some spread. The border collie x Bluetick cross produces some great dogs but there's a high proportion of psychopaths; expect 1:20 or so to be one of those puppies you just cant do anything with without insane effort. Bluetick x Catahoula are more mentally stable but likely to fall to the "merle on merle" cillia based health issues. (Digestive trouble and/or hearing issues)

Great danes x collie were robust, intelligent, big dogs that avoided almost all the inhertibale issues of the parent lines; but that's a cross you don't want to undertake raising without significant time. They're as bright as a small child and they feel they need a job: furthermore if you're not the boss, they feel they have to be. Of 4 litters (all large, hounds are profligate) we got 2 willful and bright enough I'd call them "psycho pups". Bad news at that size and vitality. Great for a herd dog, but only if you don't care about having input into how the herd is run.

Really interesting, thanks for posting. What do you practically do with the psychopath dogs/pups? Presumably the 'insane effort' required to keep them in line doesn't square well with all the other hard work your farm requires. Are you essentially forced to give the mentally unstable ones to a shelter?

I think this is one of those studies where you didn't really need to do a study.

Not OP. Dogs are pack animals, so less bright are kept in order by pack. They are still usable for guarding, but can not be used for herding or hunting.

"Psychopat" dogs have to be put down. Risk they attack something is too big. But they are rare.
