Naska von den Gänsewiesen wants to say Welcome! to all visitors of this homepage.
Here you can read something about her and her breed, the Greater Swiss Mountain Dog (GSMD).

Naska von den Gänsewiesen

Like you can see, Naska is descended from the original breeding lines: she is medium-sized and powerfully built.
The Greater Swiss Mountain Dog derives from different kinds of Molossers brought by Romans over the Alps a few hundred years ago. The starting point of the today's GSMD is situated in the Swiss mountains. The conditions there made a dog with robust health and strong build. Nevertheless the GSMDogs are able to be fast and very agile.
The Greaters are the largest of the four Mountain Dog breeds. They are traditionally working dogs: bred for watch and draught work.

Bitches have a height between 60 and 68cm, male dogs between 65 and 72cm. An adult GSMD should weigh between 50 and 70kg.

The dog's character is well-balanced, they are good guards for the whole family, house and for a plot of land. The Greater Swiss Mountain Dog is a dog who wants to live together with you, who would like to be your companion!

A great collection concerning GSMD exists in Bern, Switzerland, in the Natural History Museum. An important part is the Albert-Heim-Foundation.
Albert Heim was one of the first persons who took care of the different Swiss Mountain Dogs. The following picture from Arno v. Fryberg, S.H.S.B. 29413, born 9.08.1927, shows one of the original dogs which were part of Heim's favourite exemples of the short-haired breed: "Beauty, Form and Function". Arno v. Fryberg is one of Naska's earliest ancestors.

Besides the normal tri-coloured GSMDogs there are also 'red' and 'blue' Greater Swissies, also two-coloured in the past.
Altough they are unusual and rare colours, the dogs have the same characteristics and they are not more prone to health concerns as any other Swissy.

On the History of the large Swiss Butcher / Cattle / Mountain Dogs


One of the best publications dealing with this issue is still the work of Dr. Räber "Die Schweizer Hunderassen". The most important points regarding the origins of the Greater Swiss Mountain (and the St. Bernard dogs) are summerised here. Quotations from Dr. Räber's book "Die Schweizer Hunderassen" are in italic typescript.

The early days: cattle or cowherd dogs (Küherhunde)

There is evidence from early paintings and written testimonies that large strong dogs were kept all over Europe to protect property, drive cattle, pull carts and could be used to hunt wild boars, bulls and bears. These dogs were known as Mastins in France and Belgium, as Metzgerhunde or Hofhunde in the German spoken countries and as Küherhunde (cowherd dogs) in rural Switzerland.
These dogs were present in many colours. In the beginning of the years of pure dog breeding people spoke about black, red, yellow, grey and white dogs, black and white, black and tan, and tigered types. Some of them had markings in yellow or white.

In Switzerland, between 1550 and 1900, the so-called "Kühertum" (approx. cow-herdom) was an important form of semi-nomadic cattle-keeping connected with cheese making. The "Küher" drove large herds of cattle from the properties of the mostly noble owners to the pastures in the mountains to stay there over the summertime. This lifestyle called for the help of sturdy dogs, having a natural cattle driving instinct and a constitution strong enough to cope with the stubborn cattle and to protect the herd and the property of the "Küher" by night. Many skulls of these "Küher"-dogs are preserved in the Albert Heim collection in the Museum of Natural History in Berne. The "Kühertum" came to proud bloom in the 18th century when many cowherdsmen emancipated to become the prosperous owners of the cattle. However, they faced a steady downfall after 1830 when the cheese-making in the lowland dairies became more and more popular.

A comparison of the typical larger type cowherd dog skulls with specimens from dogs from the St. Bernard Hospice show little morphological difference, confirming the view that a relatively uniform population of "farmdogs" was spread over the main Alpine area.

The dogs of the "Hospiz" at St. Bernhard

In 1851 a certain Mr. Richardson wrote that the Monastery in St. Bernard had imported British Mastiffs in 1660 and kept them as watchdogs. This would explain to some extent the scattered occurrence of a more mollosoid skull type seen in the Albert Heim collection, but it is very doubtful where this information came from. There is no such evidence in the records from the Hospice. It is, however, believed that the first dogs were kept at the Hospice between 1660 and 1670 and these first Hospice-dogs were used as watchdogs.

A painting from approximately 1690 shows two dogs, red and white spotted, from the Hospice which are described as "Küherhunde"! (cowherd's dogs) with slightly heavier heads. The first written reference to dogs at the Hospice comes a few years later in 1703 describing using a dog to turn a meat skew in the Hospice kitchen.
Later, the dogs were used more and more to accompany monks and travellers over the pass. A detailed history of the Dogs of the St. Bernard dogs is given on the excellent homepage of the "Naturhistorische Museum" Berne.

Around 1850 the public interest in St. Bernard dogs suddenly increased. It was a master butcher close to Berne who started to breed with the dogs from the hospice. He was targeting for a type of dog close to the famous dog 'Barry' who saved many lives during his years of duty at the hospice. Many photos show that he was quite successful in his approach. But soon the public interest showed more inclination towards the heavy-headed Mastiff-like dogs as bred by others and strongly favoured by British fanciers. Incredible prices were paid for good dogs. It is no wonder that many red and white larger cowherd dogs have been sold as true St. Bernards by their owners. It was still not possible at that time to distinguish between the St. Bernard dog and the large "Sennenhunde" except for artificial definitions of colour of provenience.

The foundation of the Greater Swiss Mountain Dog breed

Around 1910 many red and white farm dogs were probably absorbed into the St. Bernard breed and among the remaining farm and butchers dog population the tricolour colouring was without doubt the most beautiful combination and fitted into the newly created family of Swiss mountain dogs.
Tricoloured dogs were never very common, and they were not exclusive to the Swiss countryside. They could be found sparsely spread elsewhere in Europe as shown in old paintings from Holland and elsewhere.

The picture shows a collage of paintings collected from members of the gsshwwdb forum which are dated between 1620 and the 19th century. Most of them are of Flemish and French origin

It was a somewhat 'by chance' decision to select animals with the probably nicest colour combination and breed them towards a unified appearance. Any other occurring colour could also have been chosen but this was not the case.
Beyond its colour the greater Swiss mountain dog has little in common with the two smaller mountain dog breeds which seem to have inherited many characteristics from the Spitz family of dogs.
When Professor Heim "rediscovered" the dogs he remembered from his childhood, there weren't many tricolour dogs to be found. He then established a breed standard for this type of dog.

A different view is given in the dissertation of Margrit Scheitlin. She follows the lines of early authors (Loens (?), Goetz 1834) who express that the butcherdogs of northern and mid-Germany were mostly black and tan with additional white markings. The occurrence of multi-coloured dogs with an otherwise typical GSMD appearance around 1900 as described by Heim and others is explained with the hybridising with other, imported breeds being en vogue during that time.
On the other side could be said that St. Bernard dogs derive from the Swiss cowherd dogs. The earliest painting in the hospice is showing as early as 1690 rend and white spotted dogs, long before dog breeding was fashion.

The Development of the Breed

World War II saw a boom in the breeding of GSMD's as they were used as draft dogs in the military service.

In the fifties obviously many dogs had insufficient colour. The black was not pure and the brown markings were often yellow. To improve their colouring crossbreeding with a Bernese Mountain Dog (BMD) was performed.

Räber states that the offspring, although beautifully coloured with short hair, lacked gait, bite and character. It was for this reason that these dogs were avoided in the use of breeding and so their genetic influence disappeared and the whole action was considered a failure. This seems to be wrong, although it is consistently repeated in many later books.

The mating of the BMD Dursli von der Holzmühle with the GSSM bitch Berna von Birchacker resulted in the male Durs von Birchacker. After 4 generations this hybrid already has more than 60 descendants among them, for example, Zarass von Fryberg. Zarass alone has, again 4 generations later, hundreds of dogs in his posterity, among them some champions. So it would be hard to find one dog today, that does not have the blood of this crossbreeding in it's lineage! Therefore, it seems the arguments against crossbreeding can hardly be maintained based on these facts.

A problem that was later faced was the lack of size. In the seventies many dogs were at the lower limit of the standard. Räber proposes a cross breeding with symmetrically marked St. Bernards.

Räber states that from the first 21 dogs in the Swiss stud book only 7 have given their genes to the present GSMDs. By browsing the Greater Swiss Mountain Dog World Wide Database can be found 8 unique dogs of unknown origin as founders of the breed being traceable back from today's dogs. But this gives a wrong impression. There are many more founders of the breed as can be seen in the pedigree of Alex von Fryberg as given in the doctoral thesis of Scheitlin. There can be counted 19 dogs, many of them not registered (probably not tricolour). Alex's line can be followed through, e.g. over Oskar von Schwärtzenberg, till the present populations. What can also be seen is that there were many more dogs in the beginning, some of them never bred, and others going into dead-end lines which faded away after a few generations, probably due to colour or structure oddities.
A probably more severe habit is the custom to use only champions as stud dogs. Thus very few male dogs are ancestors to a multitude of pubs. Genetic diversity is in this case mostly transmitted by the "mothers".
The strict limitation of coat colour in itself is no problem but it limited the number of usable dogs to found the breed bringing us to the main problem for the future which is the reduced gene pool, or better, gene puddle.


It is well known that inbred populations exhibit certain traits that are not found in normal out bred populations. This is because breeding among closely related individuals increases the probability of matching up recessive alleles. (An allele is any one of a number of alternative forms of the same gene occupying a given locus (position) on a chromosome, from Wikipedia, the free encyclopedia). In normal out breeding populations, these recessive alleles, often deleterious, are masked by normal dominant alleles. Inbreeding in laboratory populations is consistently used to uncover unusual recessive traits that a population carries in its gene pool but rarely expresses..." (Lester und Bohlin, 1989).

However, we all have thousands of different genes for many different functions, and as long as these abnormalities are rare, the probability that two unrelated individuals carrying the same abnormality will meet (and mate) is low. In the case of a population passing an artificial or natural bottleneck this possibility is dramatically increased.
This can mean that more negative dispositions will be uncovered in the form of unwanted traits, organical misfunctions and loss off overall vitality.
Inbreeding (including line-breeding) gave us the many breeds of dog we enjoy today, but it's time has passed. If purebred dogs are to remain viable into the next century breeders need to rethink their strategy and work toward their goals with more emphasis on over-all health and concerted efforts to reduce the level of inbreeding in their dogs (C. A. Sharp).

For those genes that establish breed identity, there will be markedly less variability within a breed than within Canis familiaris as a whole. The tricky part is restricting variability for those genes that make a breed distinctive without sacrificing the variability/diversity that is necessary for good health and long-term survival of the breed. In many cases, this has not been achieved, and we are now paying the price in terms of high incidence of specific genetic diseases and increased susceptibility to other diseases, reduced litter sizes, reduced lifespan, inability to conceive naturally, etc. (Prof. John Armstrong).

Coat Colour genetics of the Greater Swiss Mountain Dog

Räber dedicated one chapter to the coat colours of all Swiss dog breeds discussing the different factors playing a major role

This first one is the black and tan gene (Loh) and the Irish spotting gene (Räber calls it Holländer Scheckung = Dutch piebald) which exhibits white markings on nose, chest, paws and tail. One issue he recognised is that the white markings may take over resulting in an ongoing colour displacement by white, ending up with white dogs, having colour spots only around the eyes, ears and tail.

Generally colour in the skin and hair of any being is determined by pigments, small particles which absorb, transmit or reflect light depending on their size, shape and material. The pigment is called melanin and exists in two different types, namely the black eumelanin and the reddish phaeomelanin. The shape and distribution of the pigment particles within a hair determines any colours we know from solid black over all shades of brown, blue and red to cream and white. These factors are determined by a genetic code in a chromosome.

Very briefly: Imagine a chromosome like a string of pearls of different materials. A pearl of one given material stands for a gene. Modifications of pearls of the same material, say differing size, are called alleles. A locus is a defined and fixed place on this string for one pearl, labelled with letters, on which you can have different sizes of a pearl (gene and allele), of one given material, defining one characteristic of the dog. Say at one locus you may choose between 3 different pearls made of wood, at the next locus you may choose between 5 different pearls of coloured glass, etc. The pearls (alleles) at one locus may therefore have different sizes which manifest a ranking. Say, the biggest one is the most dominant one, the smallest the most recessive one. The alleles are labelled with the locus letter, mind the case and possibly a superscript, e.g. ay. In a mating the sires contribute each one string now, which is an arbitrary mix of their own two strings. So one string from the father and one from the mother form the code for the new pup, and, lets say, the two strings lie next to each other.


From each string (chromosome) now the bigger (dominant) pearl (allele) at one locus dictates the characteristic which will show up in the pup. The situation is complicated by the fact that some pearls at one locus dominate even pearls at an other locus, such a gene is called epistatic. This means now that if an allele is the most recessive on a locus, say the black and tan allele in the A locus, then we know that in both chromosomes (strings) there must be the black and tan allele (if it was only present in one, it would be dominated by the other). This is called homozygous inheritance and all future generation dogs will consistently show this characteristic. On the other hand if say a dog carries the at allele but also the more dominant ay allele, the dog will show the ay colour but will inherit this colour heterozygous. This means if this dog one day mates with another dog with the same recessive at allele, in some pups two at alleles will end up in his pair of chromosomes and the dog will exhibit the black and tan colour. Recessive genes can be hidden for generations, however, when they do show up, they inherit homozygous, which means: pure.

Genotypes and phenotypes

The proposed string of alleles = the ideal genotype for all Swiss Mountain dogs having the correct colours = the phenotype, is shown in the middle of the graph. The font colour green makes alleles in their most recessive form, orange indicates an intermediate form, black the top dominant type.
Concerning the coat colours we have the first important gene which is the black and tan allele at in the Agouti-locus A: This allele is showing up in all black and tan breeds like Rottweiler and Berger des Alpes, also in some Mastins. It is overwritten by the all black epistatic allele K and by the other alleles in the A locus: aw wolf-colour, ay called sable (actually a red/yellow coat with some black hairs which would substitute the black coat in a Swissie) and as black saddle. As the most recessive allele in this group at will consistently show in all future generations.
The other most typical gene is in the S locus and is called Si (Irish spotting) defining the white marks. This gene is present in all mountain dogs and many others including the Broholmer. As it is recessive to the solid colour allele S it will also consistently show in all future generations. Therefore the two most important coat colour characteristics will be easily selectable and be bred in homozygous, that is pure stage.
At the S locus there are more recessive genes postulated, e.g. the Sp allele which would cause the white markings to expand to 50% coat area or even the Se allele resulting in white dogs with coloured spots around the ears and the tail. I suggest the action of another, yet not understood gene that steers the expansion of white when Si is present. Räber describes a continuous coat colour dissolution in early St. Bernards breeding, which suggests a gradual transition from Si to Sp to Se hence giving rise to my proposal.

The alleles at loci B, C and D cause in their recessive forms some alteration to the melanin pigments resulting in colour changes towards lighter intensities. There is evidence that they are present in the breed. From time to time blue Swissies are born having a dd allele pair. Räber reports about a beautiful havanna (brown) GSMD Fabian von Kleinroth. The havanna colour is accepted for the Appenzell Mountain dog.

At the E locus, the most recessive allele would be e, but ee is epistatic to K and A. (The existence of the K locus is not unquestioned, dominant black K was earlier proposed to be on top of the A Locus as As) This means that a dog having ee will not produce any eumelanin pigment therefore no shades of black, havanna and blue in this hair but only red and yellow phaeomelanin resulting in a red and white Swissy. Hidden K and M alleles cannot be present except when a mutation occurs or they are crossbred into the breed. K would cause all black dogs, M the spotted merle coloured individuals. Finally T would give rise to ticking within the white areas, a feature we know from Swiss Hounds


Open questions in colour genetics

The allele Em dictates a fawn coat and a black mask. (Although the placement of this allele is not undisputed; some authors place it in an own super-extension locus). Obviously the spotting gene Si is stronger when we see in St Bernards where the muzzle remains white and the black mask shows up only in the eye region. Räber mentions that the black dots, often found in the white around the muzzle are the remainders of a black mask. The E locus is said to be epistatic to the A locus therefore a combination of Em with at will result in a fawn coat with the black mask. Therefore it can be suggested that the black skin spots in the white area have a different origin. An early GSMD (tricolour) is reported to have offspring with yellow coats and black masks. This seems impossible if the bitch was also tricolour. The coat colour of the bitch is not described therefore it must have been a dog carrying the Em allele.

A further point is the sometimes occurring blue eyes with otherwise normal coloured tricolour dogs (no merle, no dilution etc).

In the future, molecular genetics will shed light on the questions which have not been solved by classical genetics. It could end up with many more loci, genes and alleles and many more chapters about inheritance to be rewritten.
