The “Fancification” of the Collie– An Instructive Case Study

 Photo of a collie from 1915.

Photo of a collie from 1915.

I discovered a rather interesting story about how the collie became a fancy breed. I had always heard that the collie was mixed with the borzoi to make its narrow muzzle, but I was later presented with evidence that this may not be the case. However, I did find that outside blood did indeed shape the collie into a fancy show breed. It was not what I was expecting. It is also a very interesting case study into what happens to a breed once they become “fancy” or, as their breeders call them– “improved.” I am going to directly quote what I found, for it is quite instructive:

The collie was the most popular pet dog of late Victorian England and a  prime example of a breed reconstructed to meet the figurative needs of fanciers. Collies were originally valued for the qualities they had developed as hardworking Scottish sheepdogs–intelligence, loyalty, and a warm shaggy coat. Once they were firmly established in the Stud Book, however, breeders began to introduce  modifications and improvements, which were tested not against the rigors of the Highland winter, but in the fashionable marketplace. [Emphasis mine] By 1895 there were seven independent clubs devoted to the breed’s welfare, many of which sponsored all-collie shows, as well as strong collie representation in the Kennel Club and regional canine associations. The large number of pedigreed collies seems to have been exacerbated the tendency of fanciers to fabricate subtle points of distinction between animals and artificial models to measure them against.  As a result, fashions changed swiftly and collie standards were among the most volatile; breeders redesigned their animals or restocked their kennels in accordance with the latest show results. Plasticity could even take precedence over pedigree; in order to instill some temporarily admired attribute, breeders were sometimes willing to contaminate the strain. In the early days of showing, collies were often crossed with Gordon setters to achieve then fashionable glossy, black-and-tan coats. For decades experts could detect “traces of the bar sinister”– telltale ears, head, and general heaviness– in many show animals.  Even without crossing (which became less common after the Stud Book gained sway), fashion could undermine the character of the breed. The 1890s saw a craze for exaggerated heads with long, pointy noses. In 1891 a Kennel Gazette reviewer complained that show judges had given away all the prizes “to dogs of the greyhound type whose eyes bore an inane, expressionless look.” Critics alleged that such dogs could hardly display the intelligence characteristic of their breed because there was no room in their heads for brains.

Harriet Ritvo, The Animal Estate: The English and Other Creatures in the Victorian Age (1989) p. 113-114.

Now, these developments partially explain why the fancy went to the closed stud book system. That certainly could reduce volatility in type, but dogs have such plasticity in their phenotype (because of tandem repeats) that fad breeding can still lead to massive shifts in type.

I’ve seen it in my own breed in just a the past few years. To me, the most of the goldens that are being offered today are nothing like the dogs I remember. The type has shifted from a more moderate and less exaggerated dog into something more heavily built and excessively feathered. The color range has shifted almost entirely. One can no longer find the darkest mahogany color in goldens, unless one really looks hard and doesn’t automatically assume that light builds and dark colors are indicative of cross-breeding with Irish setters.

So in that piece we see that one breed of dog started out with functional behavioral and physical conformation, and after just a few decades of fad breeding, it becomes a very different dog. So much for the fancy preserving dog breeds. The fancy may have that intent, but as an institution, it is very much susceptible to fads and trends, as well as contrived characteristics that are actually detrimental to the health and function of the dogs. What shepherd would want a collie with such a narrow head and very little herding instinct?

Now, I found it interesting that Gordon setters were used to increase the number of black-and-tan dogs in the bloodline. However, black and tan  and solid black were the most common colors of the British herding landrace that became the collie-type dogs. The Gordon setter got its black and tan coloration from an outcross with a black -and-tan collie. One must remember that Queen Victoria’s collies were all black-and- tan, but that particular coloration may not have been universally evident in all show collie populations. So the best way to remedy that problem was to cross-breed with Gordon setters.

I’ve heard of other such outcrosses with show dogs. Many of these have been clandestine, for the modern institutionalized fancy is based upon a closed stud book.system.  For example, I’ve read that Labrador breeders crossed in golden retrievers to reduce houndish characteristics in yellow Labradors, as well as to increase biddability (which was always a perceived problem in yellow Labradors) and lengthen the coat. As well all know, the yellow Labradors were heavily outcrossed to lemon foxhounds to increase the likelihood of producing that color, which was not evident in the St. John’s water dog. It is also well-known that flat-coated retrievers were heavily interbred into Labradors to make them more competitive in early twentieth century field trials. The faulty black-and-tan color in Labradors has always existed within the breed and within the old wavy-coated retriever, which is the ancestor of the flat-coat and the golden, but I’ve come across more than one person who claims that the black and tan color in Labradors is the result of interbreeding with Rottweilers. However, I think it is much more likely that the color is the result of the founder effect from the St. John’s water dog and from the infusion of collie and Gorden setter blood in the old wavy-coated retriever.

So the early fancy had license to crossbreed for phenotype, and the modern fancy has always had rumors about clandestine crossbreeding. My response is actually quite simple: Why can’t we have license to crossbreed for health reasons?

How could this be accomplished? Well, in the early days in which retrievers were separated into show dog breeds, there was a class called “Interbred.” Interbred dogs were a mixture of two different strains that the KC had declared separate breeds. These dogs would be run as “Interbred,” as would their offspring for three generations. After being bred to a specific breed for three generations, the phenotype of  the descendants of this interbred dog would be examined to allow it to be registered as a purebred.

I don’t see why such a system could not be implemented today, but I do worry that fad breeding would run amok in such a system, as it did with the early show collies. That is why breed standards must be evaluated and written with functional conformation in mind. Such a system is entirely absent in the dog fancy right now.

We also need controls on how often a stud dog is used to keep the gene pool more open. Today, virtually all dog breeds (especially mine) are suffering from a compromised gene pool– most of which can be blamed on using just a few stud dogs to produce a high percentage of the offspring.

I would be very happy if we got some of these reforms. It would mean that we’re finally thinking about dogs are organisms and as creatures that have feelings, emotions, and intelligence. I can’t imagine any conservation organization that would try to breed endangered species under such a weird system. Indeed, in the case of the subspecies of cougar called the Florida panther, the Texas cougar was introduced to Florida to increase genetic diversity.

But dog people don’t think like biologists. They think like proper Victorians.

One of the greatest series ever

Source.

I have some complaints. Alby was known to re-film and contrive scenes. In fact, I’m sure most of this clip was faked.

He also was (I think incorrectly) accused of throwing a dog off a  moving truck. The dog jumped off  to chase a kangaroo. I believe that some dogs would actually do that!

There’s also a controversy about his infamous wreck in Brazil, which led to an even more infamous journey through the Brazilian hinterlands into Peru. That comedy of errors that was his attempted crossing from Brazil into Peru is one of my favorite Alby Mangels segments. (Hint: He doesn’t make it–not even by donkey!)

Despite the controversy, I used to watch the Travel Channel series that was made from the films. It was something of an evening ritual.

The two ancestral English Hounds

The Old Southern Hound.

The Old Southern Hound.

Coonhounds, foxhounds, beagles, harriers, and bloodhounds are thought to have descended from two ancestral English hounds. These dogs were the North Country beagle and the old southern hound.

Now, I will claim that the bloodhound is at least partially descended from these dogs. However, the official history is that these dogs descend from the dogs kept at St. Hubert’s Abbey in the Ardennes. However, I found a somewhat iconoclastic breed historian who claims that the bloodhound has a British origin and was always distinct from the St. Hubert’s hound.  As someone who also thinks breed historians should be willing to look at the historical record more closely, I can’t help but mention it.

The old southern hound was rather like a bloodhound or a coonhound in build. It had long, heavy ears and a pendulous dewlap. It came in all the colors we associate with hounds, so maybe the best way to think of this breed is that it was something like a cross between a foxhound and a bloodhound.  Maybe another way of thinking of these breed is that the beagle is supposed to be a bred-down version of this dog, just with shorter ears and no dewlap. Its influence is probably strongest in American coonhounds, and I would not doubt that it may have had some influence in the development of the  British lines of bloodhound. These dogs were meant to track old scents and follow a blood spoor, usually while leashed.

It may have been derived from the Talbot, which was a white hound of rather nebulous ancestry. The Talbot may have been derived from the actual St. Hubert’s hound from Belgium, or its ancestry could have come from some sort of French white hound of which there were many breeds. Some of these exist today, like the Billy and the Porcelaine.

This old southern hound’s geographic range was south of the River Trent. It would make sense that this hound would have a bit more influence from dogs from the continent.

North of the River Trent was the North Country beagle. It was a cross between a heavier hound (maybe a Talbot) and a greyhound. It was faster on the trail than the old southern hound. Its influence is more strongly seen in foxhounds, trailhounds, and harriers, which  were developed from crosses with this breed and hounds that were used run stags.

Out of these breeds, we get a plethora of British hounds. It is likely that French hounds and other continental breeds had some influence in these dogs, but from the late Medieval period to the early eighteenth century, the main hounds in Britain were the southern hound and the North Country beagle.

How big are Steller sea lions?

Steller Sealions

I’ve never seen them up close. I’ve only seen them at a distance at zoo.

But this post at Hoof & Paw gives you an idea of how massive these creatures are.

I remember reading somewhere about a Steller sea lion that showed up in Britain, but I can’t find the article online.  Does someone know of a link to that article?

Britain's first killer shark?

basking shark

This video purports to be footage of a white shark off the coast of Cornwall.

Although it is possible that a white shark could show up there, this specimen is not one.

It is a basking shark. Now, it’s very easy to mistake the two species. Indeed, Kipling’s “The White Seal” claims that Kotick survived attacks from the “basking shark.” Kipling most likely meant the white shark, but in those days, it was not uncommon for people to refer to basking sharks and white sharks as if they were the same species.

They are not. Basking sharks are similarly built, but they can get substantially larger than white sharks. In fact, it is very likely that reports of huge white sharks are actually misidentified basking sharks.

Now, how do I know this is a basking shark. Location tells me a lot. White sharks are very rare north of the Bay of Biscay. (Check out the range map) It is possible that one could make it to the coast of southern England. Location is a good hint, but it is not foolproof.

Now, it is well-known that white sharks try to avoid boats. Jaws is mostly fiction mixed in with some out of date biology. If a boat approached a white shark, it is very likely to swim quickly away. It is unlikely to stay unless some food source or potential food source was the water.

Basking sharks tend to ignore boats and lazily swim along as they filter feed. It seems to me that this is the behavior that this shark is exhibiting.

Now, behavior is also not fool-proof. Sometimes white sharks do things you don’t expect, and it would not be unreasonable for one just swim around really slowly, even if a boat approached. It is not normal behavior, but it is possible behavior.

The best way to tell that this is a basking hark is the fin is too rounded.  (Compare the fins). White sharks have a more pointed fin than basking sharks do. In fact, basking sharks have very rounded fins compared to other shark species.

So Britain doesn’t have its first killer shark after all. It’s just another basking shark.
