I am a Coton de Tulear –breeder and also a member of our breed club’s breeding committee. Genetic tests became familiar to us breeders a few years ago. We started testing for an inherited eye disease, CMR (Canine Multifocal Retinopathy) that follows an autosomal recessive mode of inheritance. Samples were collected during our club’s annual Spring and Autumn Days. In addition, many breeders had their dogs analysed on their own. I got pretty soon involved in the process also as a sample taker because of my veterinarian background. Some of my own dogs were tested already then as well.
Genetic Diversity, Problematics of Popular Sire Syndrome, and Benefits of Comprehensive DNA testing – Real-life Examples from the Coton de Tulear Breed
The world’s most complex and comprehensive genetic test for dogs, MyDogDNA, has been available for all dog owners for about a year. During this time, Coton de Tulears have been tested to the extent that it is possible to have a first look at the diversity level of this breed. This article also describes a real-life example, encountered in the breed, of how a genetic defect causing a genetic disorder can spread rapidly through popular sires.
MyDogDNA database contains a large amount of genetic information and resulting graphs for each dog. Despite the amount of information, the service is easy to use and using it doesn't require high knowledge of genetics or information technology. To help getting started, here is a short introduction on how to view the MyDogDNA pass and all results in it.
Hunting dogs are close to my heart, especially all nice spitz-type breeds. Currently I have those of three different breeds: Norrbottenspitz, Finnish Spitz and East Siberian Laika and with these dogs we hunt, compete, do all kinds of activities and also little breeding.
Lagotto Romagnolo is a working dog of Italian origin. It is an ancient "breed"; Lagotto-looking curly coated dogs have been portrayed in narrative images, describing fishing and hunting, found in Etruscan tombs. Originally, this multi-talented dog has been a reliable guard dog and hunters' loyal helper (as a retrieving dog) for the people in the lowlands of Romagna region, valley of Comacchio and swamps of Ravenna. Lagotto has a very good sense of smell and it was already in those times used for searching truffles.
The MyDogDNA database gets constantly updated with new features and functionalities. As the latest functionality, we have added the possibility to review the plots on genetic differences on the basis of different dog related information. Pictures below present the different views available and gives instructions on what kind of new information can be obtained.
A comprehensive genetic analysis enables simultaneous assessment of genetic disorders, genetic traits and genetic diversity, on both individual and breed level. The gathered information can be utilized concretely in breeding, alongside pedigree information. Here we give a brief introduction to genetic diversity assessment results in Irish Soft Coated Wheaten and Kerry Blue Terriers with MyDogDNA.
Today, DNA information can be widely utilized in breeding and in efforts to preserve a breed's health. With the help of DNA testing, it is possible to get information about hereditary diseases and characteristics as well as about genetic diversity and genetic differences, both on an individual and on a breed level. Comprehensive DNA information can thus be harnessed to be a powerful and efficient supportive tool foor sustainable breeding.
The English Cocker Spaniel is an old British bird dog breed, whose origins are in land spaniels. The spaniels were quite a mixed population at that time: dogs were of different colors and sizes, and were used to drive game towards hunters’ nets, hawks and later towards their guns. Other spaniels and setters originate also from the same population. The first mention about Cocker Spaniel dates to early 19th century. It became a separate breed in 1892, when the Kennel Club made a separation between the Cocker Spaniel and the Field Spaniel.
With the help of DNA testing, it is possible to get answers to a wide range of questions related to the health and appearance of an individual. These answers often raise even more questions and professional advice is needed for support. The amount of information received may seem daunting, even leading to questioning its necessity. However, when used correctly, the information can be harnessed to be an effective tool helping to solve many dog- or breed- related problems. Therefore, it is good to return to a most fundamental question: Why is canine genetic testing worthwhile?
We bought our dog Sampo from a farm on the island of Kemiö in Finland, in February 2006. The lady of the farm told us that they had deliberately let their mixed-breed dog mate with the neighbour's dog, which was also of mixed-breed. She told me that there were five different breeds in Sampo: Samoyed, Husky, Lapponian Herder, Golden Retriever and Border Collie.
The Golden Retriever is one of the most popular popular dog breeds in the world. However, only a small proportion of the Golden Retriever population is actively used in breeding, and, therefore, the Golden Retriever breeders and enthusiasts are now interested in learning more about the genetic diversity in this breed. The estimations based on pedigrees (coefficient of inbreeding) don't necessarily reflect the genetic situation of the breed. A more detailed overview can be obtained by making use of DNA information.
What does MyDogDNA reveal about Bernese Mountain Dog and other Swiss Mountain and Cattle Dog breeds?
Bernese Mountain Dog is a breed of Swiss origin and the most popular breed among the Swiss Mountain and Cattle Dogs. The population has spread around the world and therefore different lines can presumably be identified. Nevertheless, all individuals of this breed have their origins in Switzerland. How does this show in the breed’s genetic diversity?
Curly Coated Retriever is a breed belonging to the retriever breed group. The population of Curly Coated Retrievers is relatively small: globally, the estimated population size for the breed is only about 6 000 individuals. In Finland, about 40 Curly Coat Retrievers are born every year. To have an overview on the situation of this breed, both in Finland and globally, the Finnish Curly Coated Retriever Breed Club Kiharakerho ry has made the decision to start a project aiming at identifying the genetic health and diversity of this breed and its breeding base.
In the statistics below, we give you an updated overview to genome-wide measured genetic diversity levels in different breeds. This table helps you get an understanding of what kind of differences there may be between breeds in terms of heterozygosity. The information gets updated with each new tested dog in the MyDogDNA database and thus refers always to the latest data available.
