I would prefer to have hyper-vigor over a purebred any day. They are much nicer and live longer.

You may get your wish.

In many states left-wing, nanny state wackos are working very hard to put breeders of purebred dogs out of business, usually in concert with Humane Society of the United States. HSUS is a wolf in sheep's clothing that is only out for itself. It's actually the ACORN of the animal world.

read quite a while back that the point of breeding those 2 breeds was to get a dog that had the nature of a lab and didn’t shed...poodles don’t shed the same as other dogs...

Why do people keep repeating this “hybrid vigor” myth?

1. It’s been scientifically disproven. George Padgett and others have researched this issue and discovered that the claim that mixed breed dogs are healthier, live longer, have fewer diseases is based on no scientific data and is disproven by study data looking at dog populations.

2. It only applies to different species (and only in some cases). When you breed a rottie and a golden together, they’re the same species.

3. Think about it for a second: if you breed a poodle that has heart problems to an Irish setter than is predisposed to have hip dysplasia, do either of those genetic problems go away? Of course not! The late geneticist George Padgett studied this and found that there are over 100 hereditary diseases within mixed breeds. Furthermore, most mixed breed matings are either by or not done by reputable breeders. Thus, two dogs who have not been OFA certified, have not had genetic testing, get paired. The resulting litter is not a better dog with fewer diseases.

Finally, owners of purebred dogs are more likely to check for heredity diseases than some mixed breed owners. That’s not entirely true (there are irresponsible pure-bred owners and great mixed breed owners). But when people have measured (like Padgett) they find more heredity diseases with mixed breed dogs. This does not mean that a mixed breed dog is a bad dog, only that health or “hybrid vigor” are not reasons for designer dogs.

“only in certain circumstances: when a hybrid is seen to be superior to its parents, this is known as hybrid vigor. When the opposite happens, and a hybrid inherits traits from their parents that makes them unfit for survival, the result is referred to as outbreeding depression.”

True hybrids are the product of breeding two different species. Breeding a donkey and a horse produces a mule, breeding a lion and a tiger produces a liger or a tigon, while breeding a wolf and a domestic dog produces a wolf hybrid. Each of these hybrid breedings is a cross of two different species. The offspring are hybrids. Domestic dogs are the same species. When you cross breed domestic dogs you are not technically creating a hybrid.

Responsible breeders try to identify genetic diseases their dogs might be carrying and to eliminate them by careful breeding.Also, if you stop and think about it, many mixed breeds are simply not tested for most problems. When they get older and limp, it’s just considered old age, although it could well be hip dysplasia. When they get older and start to go blind, it could be PRA, but the owners are unlikely to test for this.

An excellent set of articles dealing with “hybrid vigor” can be found in DogWorld, Jan 1997 by George Padgett DVM. Another very important point to keep in mind is that when a purebred carrying a genetic defect is crossed with another breed or mixed breed, the “bad” genes do NOT “go away” even though they may not be expressed in the offspring. If crossed with another dog carrying the same defect, the offspring of that breeding will demonstrate the defect.
