How Are New Dog Breeds Created?

I love dogs, I’ve always loved dogs. But
there’s always the debate… purebred or mutt? It’s a great year to be a dog lover! Apparently
7 new dog breeds will be shown at the Westminster dog show! I don’t know about you, but dog
shows… give me mixed feels. On a personal level, PUUPPIES, but the science part of me
wants to know, why are there so many different dog breeds and is that good for the species? I mean domesticated dogs might have been around
for 40,000 years and all pretty much looked like wolves. But the few hundred dog breeds
we know and love today, have only been around for a couple of hundred years at the most.
Humans tinkered with dogs, selecting for temperament or physical traits. Things like distinguishing
markings, the color of a coat and other physical features like head and body shape. A new dog breed has to meet very specific
requirements to qualify as an official breed. Many organizations like the American Kennel
Club demand proof that every dog used to make the new breed was a certified purebred. And
in many cases, breeders need to get their dogs DNA and genotype tested to show a “an
acceptable DNA variation sample for the breed”. Since 2003, researchers have been able to
see exactly what that genetic pool looks like thanks to an effort lead by Ewen Kirkness
at The Institute for Genome Research which sequenced the dog genome. They also studied the genomes of different
breeds. And not surprisingly they found that the variation of genes was greater between
dogs of different breeds than they were within the same breed. So, a black lab and a golden
lab will have less variation than a black lab and a bulldog. But what’s interesting
is that variation can be as much as 27.5 percent between dogs of different breeds, even though
essentially, they are the same species. Now compare that to humans who only have a genetic
variation of 5.4 percent. When humans mess with dog’s shape and coloring,
they are actually messing with their genes. Like size is pretty much controlled by one
gene on chromosome 15 called insulin-like growth factor-1. (IGF1), which is known to
influence body size in humans and mice. But it’s mutation can be found in a lot of unrelated
smaller breeds, suggesting it’s ancient. Even though it’s a few thousand years old,
it’s a change that still happened faster than it would happen naturally. So all the
tinkering humans do to dog breeds, dramatically changes dog’s genes faster than nature would. With all that genetic tinkering, some weird
stuff happened. Not surprisingly, breeding for aesthetic purposes has some.. unintended
consequences. Like pug encephalitis and hip problems in German shepherds. And one study
in PLOS One found that changing a dog’s face, changes their brains too. In dogs with
short snouts, their brains have rotated 15 degrees backwards and the smell region in
their brain is in a completely different place from other breeds. And these kinds of brain
changes are common in other dogs too. Another study also published in PLOS One found
that Chiari malformation in dogs actually changes their skull and brain formation. It’s
a physical defect that occurs in a lot of small dogs that are bred to look more “doll
like”. It basically makes the forehead bigger but also changes the brain shape. It can cause
chronic conditions like headaches, problems with walking or even paralysis. One of the
lead authors of the study Clare Rusbridge, described the condition “as trying to fit
a big foot into a small shoe.” Which just sounds utterly painful. The physical defects caused by inbreeding
is a huge problem and it’s one of the reasons why some breeders are calling for stricter
regulations and practices. Thankfully there are responsible breeders who are using genetic
science to ensure they are breeding to maintain genetic diversity, resulting in new breeds
that are both healthy and happy. While we’ve bred dogs to be stronger, smaller,
or even more docile, they all come from a wolf like ancestor thousands of years ago.
At some point, dogs evolved to become man’s best friend? When did this take place? So what’s your fav dog breed? Mine’s a

    +Seeker 1st of I have to correct you Julia at 3:48 – Foxes are NOT related to the dog or the wolf. Foxes are a member of the "cat" or Feline family. Strange I know. My favorite breed of dog that I recommend to ANYONE is called the kelpie. Which stars in two movies made in Australia – "Red Dog" and "Red Dog -true blue". The American Kennel Club stupidly doesn't classify the Kelpie as a dog breed. IT IS what else would you call it, a fish?

  32. One Sick Chick says:

    Please forgive me for being the pronunciation police, but it’s called a Chiari Malformation, with the “Ch” pronounced like a “K” (Ki-ari)… I should know because I also have one. The drastic rise in human Chiari diagnoses over the past several years has been credited to the MRI and its ever increasing resolution quality. I’ll try & explain it in as simple terms as I can: basically the vault at the base of my skull which holds the cerebellum formed too small (a birth defect called a neural tube defect and related to Spina Bifida), so part of my cerebellum herniates (or gets crammed) down into my spinal canal, which disrupts the flow of spinal fluid. Often when this disruption happens it causes a lifetime of damage, pain & even permanent disability (as in my case). In my case, the disruption in flow of spinal fluid caused a cyst or cavity to form in my actual spinal cord from T5-T8 (a secondary condition called Syringomyelia), which then caused scoliosis. I now also have damage to my optic nerve from bouts with hydrocephalus or increased intracranial pressures as well as other related damage. Sadly, the only real fix is brain surgery, but it’s not guaranteed to help and many people end up worse off with complications because it’s such a highly invasive surgery. I believe I heard somewhere that Chiari in dogs is most common in Cavalier King Charles Spaniels. Not sure why, but likely the way they were bred and the unique positioning of their brain & skull.

  41. DollyBear X says:

    People say a mixed breed is healthier, but not necessarily!
    For example if you cross a border collie with a Labrador, as this conception is believed, people don't health test their dogs, the puppy could get hip dysplasia.
    However, if you're breeding two labs together, you'll most likely health test them, resulting in a healthier puppies!

    Also, you said Golden lab, that's a yellow lab! A golden lab isn't a thing, and a golden retriever X lab is called a Goldador, so no, a golden lab isn't a thing at all!

  52. Paige Fink says:

    The 7 "new" breeds you mentioned at the beginning aren't new. They've been around for many, many years. They just weren't registered by the AKC. They were registered in other countries and you could show them in the miscellaneous group or at UKC. They didn't just create "new" breeds as those take years to develop. Also, why do you have mixed feelings about dog shows? Dog shows have nothing to do with how breeds were created. They have changed how SOME breeds have evolved. Some haven't changed much. For example, the AKC English Setter breed standard hasn't changed since 1909.

    "A new dog breed has to meet very specific requirements to qualify as an official breed. Many organizations like the American Kennel Club demand proof that every dog used to make the new breed was a certified purebred."

    One would have to be a mutt to give any importance to such organizations. The Pomeranian was created in 1764, the German Pinscher dates back to at least 1780, the Old English Sheepdog dates back to at least 1771 and so on. The American Kennel Club only goes back to 1884. The orgins of most dog breeds are considerably older than the AKC. Very few of these have purebred certification (people at that time were more concerned with successfully breeding desirable characteristics into the dogs than in pomp & ceremony). So, presumably the AKC don't consider these to be separate breeds. Shows just how stupid the AKC are. And even more stupid are the idiots who defer to their opinion.

    Hmmmmm let's make a wolf and a fox have sex and that "wox" will have sex with a fox again and boom you have a "super wox" then just breed "super woxes" with each other. Then make them super friendly over years, boom tiny dowgie. Will work 10/10 IGN

  62. News that matter says:

    Americans don't seem to understand that a pitbull terrier will always retain that unpredictable aggression due to breeding. No amount of traing will correct that. More than 90% percent of all dog attacks in 2018 have been from out ills and all deaths have been from pitbulls. It's not the owners. It's the dog.

  67. James 420 says:

    Pure breeding is inbreeding you’d think people would pay $2,000 for a healthy cute dog but instead they pay it for a cute dog with a bunch of health problems. I feel bad for my Lhasa apso I don’t think she’s 100% purebred she’s not akc registered but she’s definitely like 80-90% Lhasa apso. But anyways I feel bad that she’s so small she doesn’t think she’s small and she could never hold her own in a fight with another animal or dog. This person I knew had 2 Lhasa apsos and a husky herding dog mix (idk what kind specifically) and her Lhasa apsos would sometimes fight with the big husky mix and one dog got its eye poped out because of how it was bred it’s eye was already almost outve the socket and then the next Lhasa apso got its eye popped out then one time when I was over at their house the Lhasa apso fought it again for no reason and it’s other eye popped out while I was there and she died at the vet. Then the other dog got its last eye popped out and went blind. I don’t know why they never got rid of the husky or something. But it just shows how fragile these dogs are and it’s really sad to me I always have sm anxiety that my dog is gonna get her eye popped out or snatched up by an eagle or something. It just makes me so mad how far we’ve gone as humans just so we could have nice looking dogs at the expense of their health and well being. I personally like mixed breed dogs way more they almost always look unique

    0:40 False, there are dog breeds that are between 2000-8000 years old. MOST dog breeds have been created recently, but types (sheepdog, livestock guardian, sled dog, scent hound, sight hound, pest control, toy dog, etcetera) have been around for thousand of years, and some breeds truly have been isolated – on islands or up in the mountains – for that long, and are pure breeds for a very long time.

  82. Deft Advocate says:

    The video gives an inaccurate idea of what is happening when a new dog breed is being added to the American Kennel Club registry. The new breeds that are added, have usually been in existence for a very, very long time. Many of them are from other countries. When the AKC adds the breed, it means there are now enough dogs of that particular breed owned by people in the United States, so that the AKC will allow those dog owners to form what is called a parent club, to represent the breed in the United States. The new breeds may actually have existed for hundreds or even thousands of years, but they either never existed in the United States, or they never existed in the US, in sufficient numbers, for the AKC to recognize a parent club for them, or no one wanted to form a parent club for them. That is where the new breeds come from, not from new invented dog types, but rather established dog breeds, who are being recognized in the United States for the first time. The parent club then has the responsibility to tell the public everything about the breed; its sizes, its colors, its temperment, its purpose for which it was bred. Usually the parent club also knows what particular diseases may be associated with the breed and tries to inform the public how to pick a puppy, who will be free from that breed's specific diseases. That really is one of the most important functions of a breed registry like the AKC. When good breeders do their research, they will only try to breed dogs which are disease free, based on genetic tests they have done on their dogs BEFORE breeding them. Usually when breeders discover a particular family line in a breed has health problems, they avoid breeding their dogs to that line. The breeder with that line, will usually after discovering a problem, stop breeding that family line. They will then try to start over will a new family line, within that breed of dog.

    It is always important to note any dog that can be recognized as a specific breed, was bred to perform a specific task. No breed was ever really bred to just look a certain way. A German Shepherd was bred to guard flocks, a Doberman Pinscher was bred to protect, a Beagle was bred to find game and alert the hunters when it did, a Labrador Retriever was bred to recover game, and so on. None of these breeds look the way they do, because someone thought that would be a good way for them to look. Rather their looks reflect what they were bred to do, and the whatever they looked like just turned out that way. It is a classic form follows function which determined how established dog breeds look.
