The article presents the results of studies conducted at the veterinary clinic «Jean» in the city of Pavlodar. It is noted, that for the period 2013-2017. 348 cases of disease in dogs were registered by pyroplasmosis – a protozoal disease caused by parasitic organs of the genus Piroplasma. The authors described the clinical symptoms of disease in animals, as well as the nature of the flow of infectious diseases.

The article is devoted to the current problem of differential diagnosis of diseases of viral etiology in small domestic animals. Viral diseases of dogs and cats are widespread among both high-breed and outbred animals. The spread of diseases is facilitated by an increase in the number of small domestic animals, the popularization of pet keeping, and cross-border operations related to the movement of animals. The possibility of using means and methods of diagnosing adenovirus infection in cattle, tentative diagnosis and differentiation of infectious hepatitis in dogs from plague of carnivores and parvovirus enteritis is being considered. Reducing the timing of diagnosis helps to increase the effectiveness of ongoing therapeutic and antiepizootic measures. The analysis of the place of carnivorous infectious hepatitis in the structure of the incidence of dogs is given. The article describes the research in the field of the possibility of using the established antigenic relationship of representatives of the adenovirus family for the in vivo and posthumous diagnosis of infectious diseases of small pets. The authors proposed a method for performing the production of serological reactions for the diagnosis of infectious hepatitis in dogs using diagnostic tools for adenovirus infection in cattle.

Main problem: The genus Morbillivirus of the family Paramyxoviridae includes agents of morbilli, plague of cattle, carnivores and small ruminants. Plague agent of carnivores causes a dangerous disease of fur animals and dogs, which in many cases ends in death. The disease is widespread everywhere, including Kazakhstan. In our country, the mixed form of the disease is most common, and the least common is the skin and nervous forms. The chronic course of plague is observed to a greater extent with the nervous form, subacute - with mixed and intestinal, acute - with cutaneous and pulmonary forms of the disease. Goal: Veterinarians have significant difficulties in diagnosing carnivorous plague. Despite the fact that serological methods for diagnosing this infection have been developed and applied for research purposes, the lack of commercial diagnostic preparations on sale significantly restrains their use by practical veterinary workers. Therefore, the diagnosis of plague of carnivores is mainly established on the basis of the symptom complex of the disease and the data of epizootic and pathological anatomical studies, the results of which are largely similar to those in some other diseases of carnivores. Scientific research in the field of means and methods of laboratory diagnostics of carnivore plague, applicable in practical veterinary medicine, is in great demand. Methods: Considering the fact that the carnivores plague and cattle plague are antigenically closely related, studies were carried out to determine the possibility of using means and methods for diagnosing cattle plague for serological diagnosis of carnivores plague. Results and their significance: It has been established that the use of means and methods for diagnosing cattle plague makes it possible to diagnose carnivore plague at all stages of the course of the disease, their use makes it possible to reliably establish a diagnosis of the disease in fur-bearing animals and dogs in a short time after the receipt of samples of material for research, even in cases of mixed viral and bacterial infections; and also to differentiate the plague of carnivores from diseases similar to it - parvovirus enteritis, infectious hepatitis and a number of others.

Main problem: At present, service, decorative and hunting dog breeding is intensively developing in Russia and in the Tula region. So, in 2020, 119 high-breed puppies were registered in the Book of Pedigree Breeding, and in 2021 already 164 puppies, mostly decorative and service breeds. Thus, the number of pedigreed dogs susceptible to various infectious diseases is increasing annually. Canine distemper is one of the most widespread viral diseases of dogs all over the world, including in Russia. Analyzing the "Patient Admission Logs" of veterinary clinics in the city of Tula, it was found that 44 % of dogs that fell ill with diseases of infectious etiology were diagnosed with canine distemper. Purpose: The aim of our research was to study the epizootological features of the course of canine distemper among dogs in the Tula region of Russia. To achieve the intended goal, it was necessary to solve the following problem: to analyze the breed and age factors for the incidence of canine distemper. Methods: Analysis of data from private veterinary clinics reporting on the incidence of small domestic animals was used. Results and their significance: As a result of studying the epizootic situation of canine distemper among dogs, the following data were obtained: The disease is observed throughout the year and has the character of undamped fluctuations subject to sharp seasonal changes. The maximum number of diseased dogs in all years of observation is recorded in March - 6.2 cases per 1000 individuals. It has been established that among the infectious diseases of dogs, distemper occupies the first place, and there is an annual increase in the number of dogs with distemper.

Injuries among domestic animals account for 50-70 % of all non-communicable diseases. Fractures of bones, mainly limbs, occur in 44.5 % of cases. The main goal of fracture treatment is to restore normal function and movement of the limb, and the ways in which this is done are varied. Preference is given to methods that do not constrain the movement of the limb, allowing the animal to use it during the treatment period. Purpose: This article discusses the method of bone osteosynthesis, which has proven itself in the treatment of bone fractures, and is relevant today in veterinary medicine. The main study was conducted on the basis of the veterinary clinic "Shans" in Pavlodar. For osteosynthesis, plates for osteosynthesis and screws made of titanium alloy were used. This is due to the fact that when in contact with each other, the metal that fixes bone fragments can oxidize. Animals come to the clinic as a result of injuries that lead to fractures. The most common causes include falls from a height, motor vehicles, careless or rough handling of animals, and contact with other animals. When a fracture is established by obvious signs or if a fracture is suspected, such patients are preliminarily sent for x-rays. Upon receipt of an X-ray image and with the consent of the owner of the animal, osteosynthesis is performed. When accessing bone fragments, the incision was made along the muscle fibers. Osteosynthesis was performed according to the method described by V.M. Shapovalov (2009). The general condition of the animals after osteosynthesis was restored after 3-5 days. All animals, after bone osteosynthesis, completely relied on the limb. Contractures of adjacent joints and muscle atrophy were not determined. Plain osteosynthesis of the femur, in the presence of the necessary instrument and consumables, is not very difficult to perform. Performing bone osteosynthesis in the early stages makes it possible to include the limb in the locomotory act, as a result of which the animal actively uses the limb during the rehabilitation period.
