The Universal Principals of Genetics.

"Some principles in breeding are universal….regardless of breed. For example the gestation period for dogs is 63 days wether it is a shorty bull, a poodle, a shepherd or a rottweiler, they are pregnant for 63 days. Even “rock wilders” and “bordexes” are pregnant for 63 days …universal. 


If you breed a sire and dam who both carry the same faults, you’ll have some or all pups with those faults- that’s universal regardless of breeds.


ALL DOGS OF THE SAME BREED ARE NOT IDENTICAL. They are consistent in type when they have the characteristics that make them identifiable on sight. If you can look at the shape, movement, expression in its face, see that it’s coat is the correct texture, length and color and can discern what breed it is, then the dog has breed type and you recognize a Brittany spaniel from a King Cavalier Spaniel. Even spaniels as a group have traits that define them from hounds. So-in established breeds, we have groups. In groups we have breeds. In some breeds we have varieties. Varieties are smaller groups of the breed, defined from the original by variations like size or coat length. Then, we have newly evolving breeds….these composites are mixed purebred dogs. That’s how breeds begin but they are only perpetuated into a real breed when consistency in type gets locked in.

 

New Breeds receive traits from both purebred parents and the first years are usually inconsistent because all traits do not pass the same way to each puppy. When you sort dogs to breed, you should choose dogs who display the features you want the pups to have. Then, you 0sort the pups, and keep the ones who display those features for the next generation. When you do this, you are stacking the traits you want to keep and if done enough times, you’ll eventually have the traits locked in and the breed will become consistent in type. That takes a lot of dogs and a lot of years. Consistent breeds come from consistent vision and consistent sorting of dogs and that is a universal principle…


Consistent blueprints (standard) used by consistent builders (breeders) and inspected by consistent authority (judges) makes a consistent breed. Now, wether it’s established breeds or mixed breeds, hybrids, or composites know this very simple principle….


If you put it in, it will come out sooner or later. So, if you don’t want it…Don’t put it in. If it’s in there, you either breed to it if you want it, or away from it if you don’t want it. This is sorting. When you know a breed, you know lines and when you know blood, you know what it does and the more times you breed, the deeper you know it.

 

So, none of it is equal. There are no perfect dogs and as no two dogs exactly the same. Then, to make it even harder, there’s genotype and phenotype. Genotype is invisible to the naked eye, it’s the genetics - what the dog carries but does not display. Phenotype is what you’re looking at. So you may be looking at a dog with a good rear. When you breed it, you have 5 pups, 3 good rears, 1 fair and 1 faulty and you say, where did that cowhocked narrow rear come from?….that’s genotype and phenotype. It came out because it was in there, even though it wasn’t displayed. Working with the blood, you are aware of the good and the bad. Breeding generations, you as the breeder of the great grandsire, the grandsire and the sire and first hand, you know EXACTLY what’s in the blood, what you bred for and away from and where the faulty rear probably came from.


So, to think every specimen of every breed is identical or equal is the same as thinking that every breeder has the same eye and skill. Ridiculous. But do most people stereo type breeds ? All the time!! I’m sure the “rock wilder” breeder does not have the same quality the rottweiler breeder does. How many times have people assumed every english bulldog is unhealthy or that every greyhound is fast? That’s a complete misconception. Dogs are as individual as people and the very specimens we use define our generations. So, I said all that to say this- Do not stereo type breeds or breeders. Evaluate and choose what you want to see more of and don’t change your mind.


Our productions are a direct reflection of our sorting skills and our choices. Consistency in type makes a breed. "

GOOD BASICS.

"All dogs carry defective genes. These defective genes are usually “recessive” - that is, their expression can be covered up by the presence of a normal gene for that function. It is estimated that the average dog carries 4 to 7 defective genes in it’s DNA. (The human estimate is 10 to 12). Since genes are always carried in pairs, most of these abnormal genes are carried in a only single dose, so that their presence is completely concealed by the other, normal gene.


What is a gene? 


A useful analogy is that a gene is like a set of instructions given to a particular workman doing a small job on a very big construction site. Each workman gets two sets of plans. If one set is damaged, he still has one good set, and the job can proceed. But if both sets are damaged, the job will not be finished, or it will be done wrong. A gene is a large molecule, a long double strand of DNA, composed of a backbone of two long sugar molecules linked by pairs of smaller molecules called “bases” or “nucleotides”. It is the sequence of these nucleotides that encodes the information contained in the gene.


How does a gene become defective? 


During normal cell division, an exact copy is made of each and every gene in the cell, and then it divides into two daughter cells which are each an exact copy of the original cell. Defective genes are caused by a “mutation”. If something happens to disrupt the exact replication of the DNA during cell division, a defective gene results. Only a few changes in the base sequence can render the information in that gene useless. The process of aging is undoubtedly the effect of accumulated random defects of this sort, as are most types of cancer.


In the formation of egg and sperm, a special type of division takes place. Instead replicating the genetic material, so that both the daughter cells have a full complement of genes (two genes of each type), the genetic material is divided, so that each reproductive cell has only one gene of each type. When sperm and egg finally meet, the full complement of genes is restored, and a new individual, carrying half of its mother’s genes and half of its father’s genes is created.

 

Selective breeding.

 

Nearly all breeding of domestic animals is selective as opposed to random. Years ago, before the era of scientific genetics, breeding was done more by phenotype than by pedigree. Race horses tended to be bred by the stopwatch. That was where the money was. Dairy cattle were bred by the volume and quality of their milk, meat animals, by the speed of maturation and ratio of feed to meat, and so on. Later, it was recognized that breeding together closely related animals tended to speed up the process of “fixing” the desired traits within a few generations.


Breeding by pedigree is the type of selective breeding most often practiced today. It nearly always involves some degree of inbreeding. The logic is simple. We know that an animal’s traits are genetically controlled. We can even calculate the percentage of a particular animal’s genes residing in the cells of one of its descendants. When we mate closely related animals whose family shows (has the phenotype of) the desired trait, we are reasonably sure it will appear in the offspring. Some breeders have carried this practice to remarkable extremes, failing to realize there is a “catch” to the pedigree method.


What about those defective genes? The ones you can’t see because they are “covered up” by intact ones. When we breed closely related animals, (let us say because they have super rears), we can see the desired trait. This trait is genetically controlled, like all traits. These two closely related animals share the genes for their super rears as a result of their close genetic relationship. What we can’t see is the PRA gene or the kidney disease gene that these two animals also share as a result of their close genetic relationship. When we double up on the good rears we are also doubling up on the particular hidden defects they share.


We can see the results of this type of concentration of mutations in some human populations which have been relatively inbred by reason of isolation due to status, geography, or religion. Some examples that come to mind are Tay-Sachs disease in eastern European Jews, and hemophilia in some royal families.


Phenotype breeding has been largely neglected in recent years. It has fallen into undeserved disrepute as the more popular inbreeding has produced faster and more dramatic changes. I say undeservedly, because it has much to recommend it, and avoids some of the serious pitfalls of inbreeding.
Again, we look at the phenotype of two relatively unrelated animals. They both have good rears, which we want. Why do they share this trait? For the same reason that the two related ones did: they both have the set of genes which produce good rears. But what about hidden, bad genes? Since these animals could not have been selected for unseen characteristics, (after all, if you can’t see it you can’t consciously select for it), they probably do not share many of these defective genes. To be sure, they still carry their load of defects in their own private collections, but they most likely each carry a different set. This being the case, it is very unlikely that any one offspring will inherit two copies of the same defective gene. It is very likely, however, that they will all have good rears.


Phenotype breeding is still selective breeding. We are selecting those animals which show the desired traits, while minimizing the probability of doubling up on hidden, undesired ones. Inbreeding and linebreeding, on the other hand, selects for both the phenotypic and genotypic traits, and dramatically increases the probability of producing animals homozygous for defects.


The lesson in all of this is that we should pay less attention to pedigrees, particularly in terms of looking for similarities on paper when we breed, and more attention to the dogs themselves. All too many breeders make their breeding decisions on paper, and not in the flesh. We need to consider the pedigrees as they relate to the qualities of the parent animal - did his mom and dad have good rears - rather than to insist he be related to our prospective brood bitch. We can get the results we want by breeding unrelated “like to like”, without the tragic by products of inbreeding."

"THE BULLDOG CAN HELP OTHER BREEDS, BUT NO OTHER BREED CAN HELP THE BULLDOG."

 

Breeding Dogs vs. The Horrors of Inbreeding

 

A GENETIC DISORDER: WHOSE FAULT IS THAT?

In a recent post, I shared the story of Ella, a Cavalier King Charles Spaniel suffering from Syringomyelia. This extremely painful and common genetic disorder leaves a Cavalier’s skull too small for her brain.

As I wrote about Ella’s pain, I accepted that Syringomyelia is genetic with the same ease as I accept instances of hip dysplasia. With this ease of acceptance comes a question of hopelessness, “Aren’t dogs just victims to the cruelty of unpredictable biological fate?” This is not the case.

To believe that a dog’s genetic disorder is natural and unavoidable is to accept that Darwin was wrong. He wasn’t. When we open our eyes and embrace the fact that humans are undeniably responsible, only then can we change the outcome for the future of all Ellas.

 

REMEMBER HIGH SCHOOL BIOLOGY?

We know that offspring health is significantly compromised by matings of close lineage.  In dog breeding, “natural selection” or “survival of the fittest” is hindered by human intervention. As breeding for extreme physical traits continues from small, closed gene pools, more and more dogs are sentenced to suffer from the resulting chronic pain, resperatory issues, heart defects and seizures. It’s time we stop accepting this practice in reputable breeding circles, regardless of limited pairing resources.

THE MISFITS

In the show world, “breed standard” is an oxymoron with serious implications. If a standard requires consistency, somehow we’ve lost site of that. Certain breeds have become wholly unrecognizable when ancestral bone structure is compared, sacrificing proper anatomical function in as few as 50 years. Here are some sad examples:

Photo: Ancient vs. Present Bulldogs from the report: From Perfection to Pathetic Pathology in 100 Years by Stuart Thomson 

  • Pugs, Pekingese and English Bulldogs have been consistently bred to have compact faces. Their skulls and jaws have become completely contorted to the point of malfunction and they can no longer breathe with ease.

  • A Pug’s cute and desirable curley tail comes at the cost of a crooked spine and deformed vertebrae.

  • German Shepherds bred for show can barely walk on their hind legs while working class Shepherds with significant strength are considered anatomically incorrect an unworthy of show.

  • Bassett Hounds’ legs are now shorter than ever, leaving them ill equipped to bend without bone issues or bear the tremendous relative weight of their upper body.

  • Most pregnant English Bulldogs can no longer deliver litters without surgical assistance due to their heavier frame and lower center of gravity.

 

The physical state of the dogs listed above is nowhere near natural and should be far from acceptable. It’s time we observe extreme breeds for what they truly are, sentient beings trapped in a freakishly whimsical physique of celebrated, if failed, human design.

 

WHAT CONSTITUTES “BEST IN SHOW?”

One would think Best in Show would traditionally celebrate a canine specimen exemplary of health and stature. That is simply not true. In fact, a Pekingese known by Crufts judges to have breathing issues had to be placed on an ice pack when he became the 2003 champion, and yet his many pups were heralded for their prized lineage. Health has little to no bearing on show breed requirements.

Did you know that if Rhodesian Ridgebacks inherit the trademark ridge, the dog is susceptible to Dermoid Sinus? This sinus is an opening  into the skin along the spine that is highly susceptible to painful and sometimes deadly infection. Unbelievably, the “breed standard” deems healthier, ridgeless Ridgebacks (1 born in every 20) to be the lesser valued animal. Ridgeless pups are culled (killed) or spayed and neutered, preventing their healthier traits from reentering the gene pool.

We have to ask ourselves, “Since when is dysfunction correct and who decides?”

PEDIGREE DOGS EXPOSED, A DOCUMENTARY

Pedigree Dogs Exposed, a BBC documentary based on two years of careful research, was released in the US 8 months ago. It investigates the historic influence of the UK Kennel Club on breed specifications and highlights serious pedigree health concerns that many experts agree need to be urgently addressed.

httpv://www.youtube.com/watch?v=3O0l0f50AAk

As Jemima Harrison, the film’s producer, says:

The reason we made the film, is that we believe pedigree dogs are of tremendous value to society and that something needs to be done to arrest the damage caused by decades of inbreeding and selection for “beauty”. The film is a passionate call for urgent reform to save them before it is too late. To do that, there needs to be urgent reform of breeding practices and dog shows.

If you agree, demand a healthy reform of kennel club and dog show rules. Support breeders who ensure proper down-breeding and provide veterinary health screenings for each of their dogs. Many are equally appalled at extreme show standards. And never, ever buy a pedigree dog from a pet store where the stock likely comes from puppy mills notorious for overbreeding and inbreeding.

THANK YOU TO THOSE WHO BREED RESPONSIBLY

Let’s be very clear. Responsible breeders who consider health first and medically screen to that end must be commended for preserving the breeds we know and love. Many responsible breeders exist, love their dogs like children, and do their damndest to ensure the health of their litters. If you are one of these breeders, I sincerely thank you for all you do to protect the well being of (hu)man’s best friend.

 

 

"Sound structure is of paramount importance to every breeder that hopes to have longevity in the lifestyle of selectively breeding dogs. Sound structure is vital to a breeding program, and balance is the key to soundness. Sound structure allows a dog to do its job, efficiently and effectively, for most of its life before age begins to disable the dog. The harder a dog has to work to perform basic tasks, the harder it is on the dog’s body over the course of its life. Correct shoulder and rear angles combined with good flexibility and strength makes for a dog that moves properly, with efficiency. Efficiency of movement is always important, but keep in mind different breeds call for different structural make up and thus the physiology changes." - Miles Lanier

"As important as sound structure is, breed type must be kept a priority when acquiring or breeding to a structurally sound dog. After all, breed type is what makes a breed look like itself, and not other breeds. A dog that lacks type but possesses sound structure is still of value to the serious breeding program, so long as the dog’s lineage displays the breed type which that particular specimen may be lacking. If breed type and sound structure are held in high regard and considered of equal importance, a program built on such a foundation will grow and prosper to withstand the test of time. Breed type has four elements, the silhouette, the head, the movement at the trot, and the coat. Through a good understanding of the breed standard, we get a clear mental picture of the way a breed should look."

Whats the deal with color?

Color coat DNA is a road map to your dogs health.

There are alot of breeders pumping out some pretty fancy dogs these days...purple lilacs, lilacs, blues, dilutes, chocolates, seals, tri's, lilac tri's.....and to an untrained eye poorly structured and bred dogs seem to get a free pass based on their coat color. Breeders also sell these dogs for up to 5 x more than a regular coat color and claim its rarity.....but whats the real story?

 

Rare colored dogs are a product of diluting basic color coats in order to create almost a "pastel" color variation so to speak. Even rarer colored dogs are a product of crossing and combining these diluted color coats creating even more diluted colors.

 

The problem that arises when you dilute and then combine dilutes is that you are literally stripping away the strength from a dogs genes. This "stripping" opens the doors to a diversity of issues like skin, coat, ear, eye and immune disorders. Sure the dog is a looker for the first year or two of its life, but what happens after that? You rarely hear about the later years of these dogs lives as is the breeding world, "it's hot until its been forgot". And who pays the bill on these potential health disaster dogs? The buyer who bought it for an inflated price and inevitably, the dog itself.

 

So what should you be looking for in a healthy diluted color bulldog? Its parents. Coat color DNA is like a road map to your dogs health. If bred properly, healthy and properly structured bulldogs wearing the dilute shades can exist, but that takes time, money and patience. Alot of breeders don't have one or all of these, and cut corners to match the market with more experienced breeders. They produce for ego and a quick buck. If you insist on buying a dilute colored bulldog, despite its overall structure and tempermeant, please ask questions about its parents.

 

So back to the parents......a healthy dilute colored bulldog should not only have at least one different colored parent than itself but carry the K LOCUS. K LOCUS is the black alele responsible for grounding a dogs health. That does not mean a dog with the K LOCUS will be black in color, thats a completely different gene, K LOCUS is generally found in Dark Brindle dogs. So how can a Brindle dog create these rare colors? When a dog is a "carrier" of different aleles, it in itself does not have to be dilute in color in order to produce them. It only needs to be combined with another carrier or dominant colored dilute to produce these colors. In theory these pups, unless there are noted health issues in both parents genes that can be passed along, should be healthier. And the only way to know what your dog carries is if you DNA them.

 

This same rule applies to standard colored dogs. Two recessive parents or "homozygenous" parents can and usually produce pups with potential health issues. There is a standard rule in breeding that you do not breed two fawn colored dogs together, or two blues.

 

"Color Dilution Alopecia Primarily affects blue and fawn coats Alopecia is a term that refers to hair loss regardless of the cause. Color Dilution Alopecia is a condition in which dogs develop a gradual thinning of hair on their bodies often progressing to widespread permanent hair loss. This condition develops in some, but not all dogs that have been bred for unusual coat color, especially “fawn” (a dilution of a normally red or brown coat) or “blue” (a dilution of the normal black and tan coat). Doberman Pinschers are most affected by this condition but it has been seen in other breeds bred for unusual coat colors including Chows, Great Danes, Chihuahuas, Daschunds and others. 

 

Color dilution alopecia is an inherited condition and the coat will appear normal at birth. Most affected dogs will show signs between 6 months and as late as 2 or 3 years of age. The first signs are hair loss and dry skin and possibly a recurring bacterial infection, generally on the back where small bumps will reveal infected hair follicles. While the primary condition has no specific therapy, the secondary infection is treated with antibiotics. Many dogs will have chronic recurrent infections because of the abnormality of the hair follicles which results in an increased tendency to allow for bacterial colonization and infection. Some animals also have their hair affected on the neck and the top of the head while the face and legs are less commonly affected. The affected skin is scaly and without hair, sunburn or extreme cold can be a concern. These dogs can lead a normal healthy life with routine treatments of moisturizing rinses and shampoos and antibiotics for bacterial infections. High dosage essential fatty acids and Vitamin A supplements can occasionally be helpful.

 

Affected dogs, their parents and siblings should not be used for breeding. The condition can be entirely avoided by the use of non-color-diluted dogs in breeding programs."

 

Breeders who know their lines by having produced all their breeding dogs will know what each dog should potentially carry. If they don't, and established breeder will DNA their dogs. "Back yard" and "hobby" breeders rarely see or care about the big picture, sure they advertise that they are not "puppy mills", but with only one breeding dog and one litter a year, what do they really know, mostly from experience about not only their dogs, but the puppies they produce?

 

"You know whats in your lines by the dogs that you produce."

DNA Overview: Dispelling the Myth of the Quadruple Carrier

There are only three rare colors an English bulldog can carry: black, blue and chocolate. (Technically, blue is a dilute form of black. But, since blue has a unique genetic sequence - and since a dog can carry black without carrying blue - blue has long been considered a third color.) When a dog “carries” all three colors, he or she is referred to as a triple carrier. He or she has the ability to produce black, blue and chocolate puppies if bred with the right partner.

Here’s where it gets tricky. ANY bulldog who carries chocolate and blue can create a lilac by being bred to another bulldog who ALSO carries chocolate and blue. However, lilac is NOT a forth color that they carry. It’s simply a color that they are able to produce if bred to the right partner. There is not a unique genetic code for lilac. Lilac is the combination of chocolate and blue.

 

A simple analogy is to explain that if you have a yellow crayon and a blue crayon in your crayon box, you can mix them together and make green. It does not mean that your crayon box has three crayons - you still only have two (yellow and blue) but the two mixed together can make green. If you were to sell your crayon box and imply that there are three crayons inside and not just two, it would be misleading.

 

One might argue that if a dog can produce four colors, then it carries four colors. This is not true. A color that a dog CARRIES is genetic code that it can pass to its offspring. There is not a lilac gene that can be passed down.* Remember, lilac is the combination of chocolate and blue from both parents. In the crayon analogy, lilac is the green. And in that box there is no green crayon.

 

Knowing that a bulldog can only “carry” three colors (black, blue and chocolate) for a breeder to imply that a Bulldog carries more is not accurate. What is accurate is that is has the potential to produce the forth color. Because of this, we use the term triple carrier to accurately portray a dog’s genetics.

 

WHY IS THIS IMPORTANT? Anyone looking to add a rare-colored dog to their breeding program should realize that an accurately labeled triple carrier offers THE SAME GENETIC POTENTIAL as a dog that is said to be able to produce four colors. Paying more for the mislabled “quadruple carrier” would be foolish. Thinking you’re getting something that you wouldn’t get from a triple carrier is inaccurate.

 

* However, a lilac dog does offer a unique genetic guarantee, which is why they are so valuable. ALL of its offspring will carry (but not necessarily be) either blue or chocolate.

PLEASE DON'T JUST BREED OR BUY FOR COLOR, PLEASE MAKE THE BEST CHOICES FOR THE OVERALL BULLDOG BREED

So what should I look for when buying a bulldog?

 

Well, that is a loaded question - yet very simple. There is no such thing as a perfect dog. And even though many breeders may boast that their dogs are "perfect" they may very well be just "expectional for the breed". Genetics are a complicated game - and no one has the power to predict when and where resessive genes may pop up when bred to new studs, other lines or to dishonest breeders. Bulldogs are pricey, and when bought wih breeding contracts some sell up to 30 k. Crazy right? So it makes sense that people don't want to lose their money, or their investment. So what can you do when looking at buying a bulldog? Start with the breed type. There are many types of bulldogs and many variations on one specific breed - eg; the Olde English Bulldogge. By looking at a puppy's parents, you have an advantage to see what traits your puppy may or may not posess at full maturity. If you don't like the looks of the parents, chances are 8 out of 10 that you will not like how your puppy looks fully mature. That being said their is the odd "unattractive" dog that throws beautiful pups, and a good breeder should know this, and will tell you this.   Below is a gallery of images of different size, shapes and breeds of bulldogs for you to look through.

"The better a dog is built, the longer a dog will last. Different jobs & purposes require different breeds to possess different traits. From the silhouette, to the head, to the coat, there are variations between breeds depending on what is usually expected of the breed. For example, dogs that are bred to pull need to have good rear angles to allow them to drive off, and correct shoulder layback & angulation so that they don’t develop shoulder injuries from the harness creating stress on a steep or upright shoulder. Another example is dogs that are required to do bite work. They need correct occlusion in the mouth and correct head structure to allow them to perform their job at a high level. One more example is northern breeds that need a long, dense coat to stay warm in cold climates. These dogs must possess soundness according to their breed standard in order to be able to do the job asked of them. Not all dogs are bred for hard work, and some are simply produced to be a companion. Whether a dog and its offspring are expected to withstand strenuous work or not, there is no excuse to breed dogs that aren’t structurally sound."
