Labrador sterilization
If the owner of the Labrador does not plan to receive offspring from his pets and does not want to burden himself with the worries associated with caring for the animal during estrus, pregnancy and childbirth, then it is better to sterilize the dog. The use of chemical contraceptives (contrasex) for a long period violates the hormonal status of the animal, which is subsequently fraught with the development of such pathologies as: ovarian cysts, glandular hyperplasia of the uterus, uterine tumors, as well as the occurrence of hydrometers or pyometers. These pathologies are treated only surgically. In addition, if an unsterilized animal was not pregnant during life, then in old age (6-8 years, depending on the type and breed of animal), the likelihood of developing pathologies associated with reproductive organs also increases. In addition, it is scientifically Continue reading
Dog Hip Dysplasia
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
Inheritance of dysplasia (HD)
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
