    Greyster breed
    Opis:
    The aim of the study was to record and analyse selected biometric data based on the results of measurements of Greyster dogs actively involved in sports. The results were compared with the biometric indices of other dog breeds, including the original breeds from which Greysters are derived and Polish native breeds. The study showed that the Greysters are of intermediate height as compared with the original breeds they are derived from, i.e. shorter than Greyhounds and taller than German Shorthaired Pointers. Their height index was less than one, which means that the height at the withers was greater than the diagonal body length in the rectangular shape of the body. The chest girth was greater than the height at the withers, and the ratio of these values, expressed as the massiveness index, is similar to that of the Polish Greyhound. The Greyster eurysomia index (ratio of chest girth to diagonal body length) was also similar to that of the Polish Greyhound. The biometric parameters of Greysters allow them to run fast. This predisposition was also indicated by the leg length index and the proportions of the lengths of sections of the pelvic limb. Further research is necessary to determine all of the biometric characteristics of Greysters. The results obtained at this stage of research can be used as an auxiliary tool in selecting these animals for breeding or sport competitions. Any information with biometric data may be helpful in establishing a breed standard for Greyster dogs and classifying them as an FCI breed.

    Opis:
    Biometric measurements were made on 20 female and 20 male Border Collies. Half of the population of each sex, i.e. 10 animals (active dogs), were either currently participating in disc dog competitions or had recently finished their sporting careers due to age. The other half of the population, i.e. 10 females and 10 males, were not active in sports (non-active dogs). Most of the dogs came from Polish kennels, but some were from other countries. The following measurements were taken: diagonal body length, height at withers, chest girth, forelimb (metacarpal) girth, thigh length, shank length, foot length, and body weight. Statistical analysis of the results was performed, and the body length, massiveness, eurysomia and boniness indices were calculated. Border Collies were shown to have some biometric traits similar to those of Polish hunting dogs and Polish hounds, and some were also similar to those of Polish sheepdog breeds and Polish greyhound. The biometric analysis showed only a few statistically significant differences between active and non-active groups of Border Collies, concerning height at the withers in females and the body weight of males. Consequently, the results did not confirm the research hypothesis that the traits and biometric parameters of Border Collies differ between jumping dogs and dogs that are not active in sport, in connection with their participation in various competitions. However, it can be assumed that for the needs of sport cynology, there will be a need to select dogs predisposed to athletic performance, and analysis of the biometric traits of dogs will be a useful tool in achieving this goal. The results of the measurements collected in this study and the indices calculated from them also contribute to the biometric database of Border Collies.
