“…However, all of them showed some disconcerting data in at least one studied breed. Rare and national breeds such as Polish Hounds [ 18 ] or Ca mè [ 19 ] are usually the most affected by the loss of genetic diversity. This is also the case for the Czech Spotted Dog (CSD).…”

Loss off genetic diversity negatively affects most of the modern dog breeds. However, no breed created strictly for laboratory purposes has been analyzed so far. In this paper, we sought to explore by pedigree analysis exactly such a breed—the Czech Spotted Dog (CSD). The pedigree contained a total of 2010 individuals registered since the second half of the 20th century. Parameters such as the mean average relatedness, coefficient of inbreeding, effective population size, effective number of founders, ancestors and founder genomes and loss of genetic diversity—which was calculated based on the reference population and pedigree completeness—were used to assess genetic variability. Compared to the founding population, the reference population lost 38.2% of its genetic diversity, of which 26% is due to random genetic drift and 12.2% is due to the uneven contribution of the founders. The reference population is highly inbred and related. The average inbreeding coefficient is 36.45%, and the mean average relatedness is 74.83%. The effective population size calculated based on the increase of inbreeding coefficient is 10.28. Thus, the Czech Spotted Dog suffered significant losses of genetic diversity that threaten its future existence.

“…It is a dog with high sensitivity to stimuli; therefore, socialization is very important in its case [25]. Polish Hound breeding should pay attention to the selection of individuals for breeding because, as shown by inbreeding studies in 1960-2004, the level of inbreeding of some individuals was up to 37% [26].…”

Boarhounds are hunting dogs bred for hunting wild boar, including terriers, dachshunds, and hounds. Hunt trials evaluate the individual hunting potential and trainability of the boarhounds in ten different competitions. The aim of this study was to determine the factors influencing the hunt trials for boarhounds in a large cohort of hunting dogs. The analysis was conducted based on the results of hunt trials for boarhounds conducted in 2005–2015. The database contained 1867 individuals belonging to 39 breeds. Effects of sex, age, breed group, and breed were estimated by non-parametric analysis of variance. Sex influenced (p < 0.01) the total score, and in almost all competitions dogs performed better than bitches. Age affected (p < 0.01 or p < 0.05) all competitions, indicating that the dogs perform better with age. The results analyzed by the breed group showed that the dachshunds performed better in courage (p < 0.01) and searching (p < 0.05). Breed influenced (p < 0.01) almost all scores except obedience and tracking on the lead. The best performing breed was Alpine Dachsbracke. In conclusion, all analyzed factors influenced the results of the hunt trials. The factors with the largest impact were breed and age, which reflect both the hunting potential and the level of training of the boarhounds.

“…The common dog we see today typically goes back to just two dogs and two bitches brought over to Poland in 1959 from Lithuania territory. The breed was recognized by the Fédération Cynologique Internationale (FCI) in 1966.The current population of Polish Hounds is estimated at 1000 animals (Głażewska, 2008;Głażewska and Prusak, 2012;Książek et al, 2014). Unfortunately the low number of the founders may result in the decreasing of genetic variability and in consequence declining health condition of the breed (Frankham, 1996).…”

The Polish Hound (ogar polski) is a small, old breed of hunting dogs.The breed was recognized by the Fédération Cynologique Internationale (FCI) in 1966.A three–year–old Polish Hound male, was admitted to the Clinic of Internal Diseases of Companion Animals of Life Science University in Lublin because of signs of haemorhagic diathesis. There was no preceding history of trauma. General clinical examination was unremarkable. On initial diagnostic testing prothrombin time (PT)of the patient was prolonged nearly by three times. To characterize the dog’s coagulopathy further, samples were collected for coagulation screening tests, mixing studies and factor analyses. Investigations revealed factor VII activity below 2%.Unfortunately we had been unable to determine whether the disorder is inherited or is the result of a spontaneous mutation. It is very likely that the nature of described deficit is inherited. Canine hereditary FVII deficiency was first described in 1962 as an incidental finding in Beagles. Later, the defect was identified in another breeds, such as: English Bulldogs, Alaskan Malamutes, Miniature Schnauzers, Boxers, Scottish Deerhounds, Alaskan Klee Kai Dog and mixed–breed dogs. In 2005 a molecular characterization of FVII deficiency in Beagles was described. Unfortunately we had been unable to determine whether the disorder is inherited or is the result of a spontaneous mutation. To our knowledge this case is the first to report of isolated factor VII deficiency in Polish Hound.
