Please no bashing or ranting. I am just asking for opinions, facts, and sources. I did not breed this litter myself. I do not own either of these dogs.
If you had the opportunity to get a free puppy with otherwise good bloodlines and health tests, would you accept a puppy from a litter where the dam's father is the sire's half-brother? Why or why not? What are the possible risks or things to be aware of? Links to sources, studies, etc. are greatly appreciated!
I can tell you that the father is OFA Fair on hips and Passing on elbows, and that both of his parents are OFA Excellent on hips and Passing on elbows. Only health problems that the site has ever had were UTIs. I do not know if the dam has been tested. I will try to get more info on her and her parents though.
I own two dogs that are pretty heavily linebred...inbred...however you want to say it. I can say more about one than the other because I know more about that breeder. That breeding was carefully planned. The dogs had been used a lot in the breeding program and the breeder has been doing this awhile. I would call her experienced. I think it's safe to say she probably had a pretty good idea of what to expect those dogs to produce. There was extensive health testing. The two individual parents had a progeny list on the OFA database and had produced nothing less than a Good and several Excellents between them.
I'm happy with the dog. He is not breedworthy due to a genetic thing though. Whether that has to do with the linebreeding, I have no idea. Not something that threatens his well being.
I should have said first I'm not qualified to have an opinion about pedigrees like this because I really just don't have the knowledge. I did not research it before I bought this dog. I do have confidence in his breeder's knowledge though.
All that said, I would NOT want a puppy from what you described above. What you described as far as I can tell is absolutely not something done thoughtfully, carefully, with all possible testing and screening and deep knowledge of the dogs and the lines.
This topic came up a lot when I was breeding goats- and I think I do understand why people do that sort of breeding, to set a type, for uniformity in what they produce, etc. But I think it was a goat breeder I recall saying "you really want to know what nasties are going to or possibly going to pop up". And you really don't know. what you DO know, is that the one dog you know something about, is not as good as he can be. He has only Fair hips and a chronic health issue.
The financial burden of the sire's problem was too much for you. Who knows what kind of a worse burden you might wind up with from one of these puppies. Free sounds good until you find out what other problems it has. I'd definitely pass.
If you want to do something, do it right. If you want to breed dogs, start with a well bred dog. I wouldn't begrudge anyone who wants to learn to breed dogs. Sure you could wind up with a good dog from this. But I don't think the odds are stacked in your favor, and when you get right down to it, it's all a gamble. I would want the best odds possible for success.
Unless of course you are legitimately fine with whatever issues the puppy may have- you are sure you are going to be financially able to deal with whatever issues come up, and you are sure you are fine with not being able to breed the dog if it doesn't stack up. And please be really honest with yourself about those things. Things happen, people have to give dogs up, whatever. But don't make the same mistake twice.
