Dysplasia (Greek. Dys – prefix, meaning a deviation from the norm, Greek. Plasis – formation, formation, dysplasia – developmental disruption). Hip dysplasia (TPD) is a common disease. It was first discovered in dogs in the United States more than 50 years ago. A few years later, it was proved that dysplasia is caused by hereditary factors inherent in many breeds. Hip dysplasia is more common in large fast-growing dogs, which are characterized by a large mass and powerful physique. Both sexes are equally affected by this disease, St. Bernards, Newfoundlands, Molosses, Bernese Shepherds, Rottweilers, German Shepherds and Boxers are especially prone to dysplasia. According to statistics, this pathology is widespread, and in the absence of control measures, the frequency of its occurrence can reach 70% among these breeds.
Currently, this pathology is assessed from the standpoint of the integration effect of exo- and endogenous factors, Continue reading
In most dogs, disorders are not clinically apparent, but it cannot be considered that apparently healthy dogs are free of dysplasia. Joint pain is manifested only with a severe form of the disease. It should be borne in mind that this pathology can be transmitted through 14 generations. Many countries have anti-HD programs. The main difficulties arise in the diagnosis, a clear definition of the degree of the disease. The only effective measure to combat hip dysplasia in dogs is the rejection of identified sick animals from breeding.
According to various sources, HD heritability ranges from 60 to 20%, but the most extensive studies indicate that it averages 25-35%. When mating defective parents, the probability of getting sick offspring increases by 2 times.
It does not make sense to immediately harshly exclude all sick dogs from breeding – you also cannot Continue reading
Hip dysplasia in dogs is a problem that affects at least three categories of people.
These are veterinarians (orthopedists, surgeons, genetics, physiologists) involved in the detection of dysplasia, its diagnosis, treatment, and making recommendations for raising healthy animals. Considering the experience accumulated by dog handlers, they put forward (and then correct!) Assumptions about the causes of dysplasia.
These are dog handlers (breeders, breeders) involved in the compilation (taking into account the recommendations of geneticists) and the implementation of breeding programs aimed at reducing the frequency of this trait in dog breeds, compiling and bringing to the general public dog breeders recommendations for raising healthy animals (and checking the effectiveness of these recommendations, too )
It is the breeders themselves who want to know how to raise a healthy dog, what needs to be done to establish the correct diagnosis, what is the likelihood of this disease in the beloved dog and what to do if she is nevertheless Continue reading
