This is a load of garbage. Mixed breeds can inherit whatever health problems their parents might have had or been genetically predisposed to.
Some reading for you. While in some cases, certain genetically linked disorders are slightly more common in purebred dogs the key to dealing with this lies in less indiscriminate breeding - more genetic testing and breeding of select individuals free from disorders, not in creating more random mutts or supporting backyard breeding.
Some disorders require two pairs of the same gene. If your breeding population has a lot of the gene in it, it makes sense to go outside of it. A lot of modern incidence of genetic disorders in dogs is directly the result of selective breeding where the family lines were too close for too many generations.
Rare conditions have become more common than they would have been.
How many mutts do you know whose parents were tested for genetic disorders of any kind?
I own a mutt, got nothing against mixed breeds. But you are getting a genetic crapshoot and I hate this idea people have that mutts are healthier. Its not the truth and based on a premise that doesn't really hold up.
If you want health guarantees - get a well bred, pure breed dog from a responsible breeder who has had its breeding stock tested for genetic disorders possible in the breed. Don't buy a mutt.

It's. a. dog.
What's the quality-of-life prognoses for the dog if the surgery is done? Will another family member have to be sacrificed to scrape up the money (or won't you be able to feed the dog after you've scraped the money together)? Whenever I've taken on a pet, I made the same commitment I made when I added a child. I'd probably let a dog go that was going to have a low-quality of life regardless faster than I would a child--but that's largely because of the separate laws involved.
I'd toss a stack on the table and tell them to make it happenz.

I scanned the study and what is missing is a population of deliberately crossbred dogs whose parents were purebreds of known parentage.
Comparing purebreds to backyard mutts who might well have a shared father from the neighborhood is not a controlled study.
I still say a purebred Lab and a purebred Shepard cross all other factors being equal is a healthier dog then breeding that lab with another lab.
Nature favors the genetically diverse, I think..
Making it worth more than most humans, like you, ya fucking piece of shit.
Such as?
No....you can inbreed healthy genetics for a long fucking time and not have problems in a multitude of organisms, even humans. You can make it so much so that introducing new genetics into a long inbreed line can almost assuredly result in semi if not totally fucked up offspring.
LOL "pure" vs mutts is about as controlled as it gets bubba.....because they are all...ALL inbred wolves. Except the Chihuahua....strong controversy and evidence that they are of fox lineage.
Based upon what?
Last I checked pretty much the entire community of modern biology would disagree with that and more than likely say something along the lines of "Populations with the correct (for their environment) homozygous traits or dominant heterozygous traits for success are the ones that nature favors."
But we aren't talking about what nature favors we are talking about what man favors.
The problem is in the selective breeding, because humans don't breed pets for health...they breed for cute and friendly.
I did have this huge piece written out but I got of the biology lecture because it's unimportant...selective breeding isn't a bad concept...it's wildly successful actually in a number of organisms that weren't bred for cute n' cuddly but constitution, vigor and production. Inbred as a fuckin Texas trailer park and kicking their wild cousins ass's for it from chickens to bananas.
So....sorry if I don't take your say at face value but I'm going to need to see about 25-30 years of modern biology turned up on it's head before I buy the whole lab/Shepard F1 hybrid > standard 'pure breed' lab....cuz they are all inbred as fuck.
That makes sense.
What about genetic testing. Do we actually have good information for dogs in the 20+ disorders listed in the study?
If so, could you not simply test puppies and see which ones ought to be neutered?
