Mongrels are healthier dogs compared to pure breeds, discuss?

Look at any comprehensive breed information website and you will see the associated medical problems with the breed. Pugs for example have a smaller genetic pool than pandas (in the UK all come from 50 dogs and there are thousands of offspring). A best of bread dog may easily sire thousands of pups regardless of what genetic abnormalities it may have. So why do people insist that you should not even consider breeding a dog unless it is registered? Unless it has come from a restricted gene pool? What is so good about inbreeding dogs? Mating father to daughter is routine. Why is this seen as a good idea?

In my job i come into contact with different dogs every day, working and pets. Every week i see pet dogs, Pugs, Labradors and spaniels which are riddled with problems, bad eyes, bad joints (in 2 year old dogs), breathing problems. They are all in pure breeds, registered dogs. The working dogs, bread for health and fitness as opposed to looks are routinely healthy.
 
Breeds are predisposed to certain genetic defects but IF a dogs parents were tested for that defect there is a much lower instance of that defect surfacing in the puppies. Problem is irresponsible breeders don't test their dogs before breeding. A person who breeds Mongrels is not a responsible breeder and would not test the dog prior to breeding telling themselves they are safe because they "are widening the genetic pool", wrong, they are just multiplying the condition that their dog can get. Ask yourself this, How many labs do you know who have collie eye? Yet this becomes a concern once a border collie is mixed with a lab... By registering a dog genetic abnormalities are noted and a responsible breeder would not breed a dog with known defects.
 
Mating father to daughter is never a good idea-they are too closely related-Increased chance of genetic defect. You are confusing line breeding with inbreeding. Line breeding is similar, but the related parents are further apart which is better, but still its best to breed non related parents together as long as there the SAME breed. Mongrels aren't neccessarily healthier then purebreds.

linebreeding (mating say grandparent/grandchild, aunt/nephew).

Inbreeding reduces fertility, vigour or overall health and mental stability. Inbred animals are more prone to diseases such as infections and cancer, and more likely to be "highly strung".

But the Catch Is…
Not all outbreeding creates heterosity. In fact, in some cases, the opposite can occur. When offspring resulting from crossbreeding are inferior to their parents, outbreeding depression has resulted from the pairing. You may be familiar with a similar term, inbreeding depression, which describes the undesirable results of breeding between closely related individuals. Close inbreeding is more damaging in general than outbreeding or crossbreeding, but both types of breeding can have unpleasant and unwanted results.

Outbreeding depression can happen when a crossbreeding causes the loss of desirable recessive traits, or if two individuals who are very physically different are paired and resulting offspring receive incompatible traits from each parent. For example, if a Basset Hound were to be bred to a Mastiff, the resulting puppies could end up with traits predisposing them to serious health problems. If the Basset passed on its long back but the Mastiff passed on long legs and a deep barrel chest, the resulting puppies would be likely to suffer from slipped disks and other serious back problems.

Another factor working against the claim that mutts are healthier is a lack of record-keeping. Most mutts don’t come from bloodlines where careful track is kept of the health of every dog in the line. Purebreds may have more known health problems in their background, but sometimes this is only because better records have been kept.

So How Can You Choose a Healthy Dog?
No dog is guaranteed to be healthy for life. The most conscientious breeder could produce a dog that lives a short and unhappy life due to congenital or hereditary defects, and a shelter dog with no known family history might live 20 healthy years. However, either mutts or purebred dogs can be healthy, happy pets who live long lives. Here are a few tips for maximizing your chances of owning a healthy dog:

If choosing a purebred, choose a breeder who does all possible health testing for the breed, and who will tell you honestly what hereditary defects are present in the lines from which you’re considering purchasing a pup. No line is perfectly healthy, so if a breeder tells you there are no problems whatsoever, walk away.
If adopting a shelter dog, choose a pooch whose temperament, size, activity level, and coat type seem to suit your family. Once you’ve found a dog who’d fit in with your lifestyle, check with the shelter to see if he has any known health problems. If you have a friend who is a vet tech or veterinarian, see if they’ll take a look at the dog before you adopt. After that, it’s a grab bag– but don’t let that discourage you; you’re playing the lottery every time you adopt a pet, no matter where you get it. Any dog can get sick.
Practice good preventive care. Brush your dog’s teeth or feed raw meaty bones for dental hygiene. Make an informed decision about diet and vaccinations. Get annual bloodwork done to nip organ failure in the bud. Take your dog for twice-yearly checkups, whether he needs it or not.

Here are six common misconceptions:
1. They don't shed and are allergy friendly.
Fact: Most Lab X Standard Poodles will shed (about 1 in every litter will not shed).

Most will aggravate allergies. It takes multi-generational breeding to breeding that reduce the allergy.

This means most Lab X Poodle or ANY POODLE X will shed and aggravate allergies and asthma like any other dog may.

A note about shedding:
There is no way to know for sure if a cross-bred pup will not shed until it gets its adult coat
(between 12-18 months old).

Some pups appear not to shed until the adult coat comes in.

Lower maintenance breed! I will not have to cut the non-shedding coat!
Fact:The non-shedding coat needs to be cut 3-4 times a year. (Same as a Poodle)

Regular brushing is a must or the dog will get matts and matts can be a breeding ground for parasites!
(same as a Poodle)

As well all ear hair must be plucked so the ears won't get infected - (same as a Poodle.)

They are easier to train than a Lab.
Fact:Due to the crossing of two different breeds there can be absolutely no guarantee a cross-bred pup will
inherit the easy to train Standard Poodle personality.

It could inherit the Lab train ability.... which is not a bad thing... Labs are not stupid! But it typically
takes more repetitions to train a Lab.

They are the latest fad! A new breed!
Fact:YES they are the latest fad! Unfortunately that means once they are no longer a fad there will be many
homeless pups in animal shelters.

This has already begun in the USA and Australia. Many of these new 'designer dogs' are available at a
discount prices at animal shelters.

They are not a new breed yet! The Labradoodle (or Goldendoodle) will not be considered a new breed
genetically speaking until breeding two Labradoodles together will produce off spring which all look and
act similar to all Labradoodles. A breeding must produce the same type (phenotype) and only that type
generation after generation. This is also called breeding true or having a stabilized breed.

They are cute!
Fact:The curly haired Labradoodle looks as he does because his hair is cut into the 'Labradoodle' cut.
(Anyone with a quality pair of clippers and a bit of time can learn to clip ANY curly dog into the same
cut! This is not rocket science!)

The thing to remember is ALL puppies are cute.

No one can tell what a cross-breed will look like when it is an adult!

Remember most of the dogs life will be spent as an adult.

That cute puppy stage only lasts for a few MONTHS

They will be healthier because they are not inbred like purebred dogs.
Fact:Not all Pure-Bred dogs are inbred.

Paris Poodles are not inbred!
Pure Bred Standard Poodles are statistically the healthiest and longest lived breed of dog.

There is a misconception that by breeding two different breeds together you will produce a healthier
dog. Unfortunately this is not true.

A Labradoodle can get the genetic problems common in BOTH breeds instead of just one.

One mis-informed Labradoodle breeder wrote:
"90% of all dog genetic health problems are recessive. This means that in order for a puppy to have
the health problem, both parents must carry it. By breeding two dogs of different breeds, without
similar health problems, we are breeding puppies with far less health problems! Crossbred dogs have
far less health problems, (hybrid vigor)."

Using this theory the Lab should Not be bred to the Standard Poodle because they share most of the
same health issues! Obviously this breeder did not do their genetic research.

The bottom line is both purebred and cross-bred dogs are susceptible to potential health problems.
The best way to reduce the risk of health problems is to not inbreed, health test breeding stock and
MOST importantly make sure your breeder does extensive 10 generation pedigree research.

We have been responsible breeders of Bass-A-Poos for four years.” What is responsible about breeding dogs not knowing what the puppies will be like. Or worse yet doing it solely for profit knowing that dogs, just like the ones that they are breeding, are being euthanized . Almost every breeder claims to be “responsible.” How trustworthy is a breeder who deliberately misleads people about the value of a mutt? I think you can answer that question for yourself. Truly responsible breeders are honest and knowledgeable with a strict code of personal ethics. They care about the puppies they produce and the people who'll buy them. They would never let their puppies be sold in a pet store, and will always take their dogs back if there is any trouble at anytime during the dogs life. Would a responsible breeder deliberately cross dogs with completely different and potentially incompatible physical structures and temperaments? Would they deliberately mix any breeds? No, not when they know the results will be completely unpredictable and that there are already thousands of accidentally bred mixed breed dogs in need of good homes.

Does this mean that all producer of mixes are unscrupulous and deceitful? No, many of them are simply ignorant of responsible breeding practices and unaware of what they're really doing. Both the deceitful and the ignorant, though, prey on the ignorance of the public. Once people know the truth about these breeders and pets, people will start adopting instead of buying and the breeders will stop breeding. It is simple supply and demand

There's no doubt that mixed can make wonderful pets. Thousands of people own and love mixed breed dogs of every description. But are these unusual mixes really valuable, unique, “designer dogs”? No, not any more so than the many wonderful mixed breeds available for adoption at the local animal shelter.

Don't be fooled by the cute names, “one of a kind” titles, and the high prices! You can find “designer dogs” of every size, shape, color and personality as close as your local humane society or rescue service and at a far more reasonable cost. Why not go there first and save a life? You'll be glad you did!

Why purposel
 
You are confusing several issues here...

1. Inbreeding (or mating parents to offspring). Yep, it's bad. And you know what--there are plenty of cases of mixed breed dogs where dam or sire is mated to offspring. Inbreeding is rare among competent breeders in the US. It often happens on farms and with puppy mills and design dog breeders. That's not about mixed breed versus purebred, it's about breeding practices REGARDLESS of the lineage and breed of the dog. There is a family in our neighborhood who continually produce litters as a way of making money. They mate a female chihuahua and a male offspring of one of her litters (a mixed breed dog that is chihuahua and beagle). The resulting litters are all mixed. The matings are random and occur nearly every cycle (so a little about every 6 months). It's terrible. But that's not about purebred vs. mixed breed, it's about incompetent breeders and that can happen to ANY dog regardless of genetic status.

2. The basic argument for why mixed breed dogs are supposed to be healthier than purebred dogs is the idea of genetic diversity (or the concept of hybrid vigor. But applying this concept to dogs is falacious. First, hybrid vigor works when you cross species not breeds (ie: when you mate a horse to a donkey and produce a mule, or a lion to a tiger). Not when you mate two different breeds (of horses or cats or dogs).

Additionally, specific research on this issue has shown that mixed breed dogs have more genetic issues than purebred dogs. Dr. George Padget identified 102 genetic defects among mixed breed cocker spaniels (which was over twice the number of genetic issues identified among purebred cockers). It's not that being a mixed breed dog "waters down the genetics".

But the reality of mixed breeding is:
--it combined the genetic issues of one dog with another. So when you take an irish setter (prone to hip dyslpacia) and mate it with schnauzer (prone to cataracts) you get a resulting litter that is prone to cataracts and hip issues.
--most mixed breeding is done accidently (two dogs mate regardless of their health status or lineage) or by incompetent breeders (backyard breeders, designer dog breeders, puppy mills) who don't do hip x-rays, don't care about predisposition to tumors, mate early and often (which results in a lower lifespan for the dam and litters get smaller and more sickly).
So the issue with mixed breeders is that they're a function of the two dogs that mated (and all of their potential problems) and they're usually not mated by competent, knowledgable breeders.
 
NOTHING is good about inbreeding dogs, that is why there is such a prevalence of genetic diseases and defects in purebred dogs. I have heard that it occurs a lot more in the UK then in the United States, but I could be wrong.

As far as the health of mutts vs. purebreds, I am split on my opinion. It is very important to buy a purebred through a reputable breeder who does not inbreed, and will provide you with pedigrees to prove it. But as far as mutts, you really have no clue what you are getting, and what their pedigree or parentage might be. Mutts can develop diseases and such just as easily as a purebred.
 
Mating father to daughter is not "routine." Get your facts straight.

If there were a breed information website for "mutts" it would probably have a slew of health issues listed as well. But as far as I know there is no mutt breed standard.
 
Nothing to discuss...there is no legitimate data supporting that statement.

Mating father to daughter may be "routine" among clueless backyard breeders breeding out of convenience, but it is NOT "routine" among serious breeders who understand genetics.

Look at any comprehensive mutt information website and you'll find...nothing telling you anything about their health problems. Why? Because nobody keeps track of mutts' pedigrees, and nobody tracks their illnesses - so how can you even compare the two?

Small gene pools are a problem in the UK, because you live on an island with quarantine laws. Please do not use your own situation to paint all of purebred dogdom with the same misrepresented brush.

I don't care if a dog is registered or not - what I do care about is that any dog bred is bred for a legitimate purpose: To strengthen and maintain the health and integrity of an established breed; or to fulfill a working function.

There is really no point in breeding a dog - mutt, purebred, or otherwise - if it does not do one or the other. Since mutts obviously don't fit into the former category, and rarely fit into the latter...why breed them?
 
MYTH!!!! You need to stop listening to the PETA folks.

Responsible honest hobby breeders have diligently bred out the vast majority of genetic diseases through careful breeding and culling.
