At this stage, keeping pet dogs has become a popular fashion and lifestyle for people. As companion animals, pet dogs can provide their owners with special emotional support and life security. However, during their growth and development, most pet dogs will inevitably develop various diseases. Therefore, pet dog breeders should regard scientific response to canine diseases as a required course. Based on this, it is necessary to take parvovirus disease, a typical and high-incidence canine disease, as a research object and explore and discuss its comprehensive prevention and control measures.

01

Cause of disease

In recent years, parvovirus disease has shown the characteristics of high outbreak and high prevalence in the field of dog breeding in my country, and has shown high mortality rate and treatment cost. Therefore, we must attach great importance to the prevention and control of this disease and do a good job in analyzing its pathogenesis, so as to reduce the occurrence probability and harm of parvovirus disease in pet dog breeding from the source.

Based on industry experience, there are many reasons why pet dogs are infected with parvovirus: First, sick dogs are the main source of infection for parvovirus disease. After dogs are infected with parvovirus, pathogens may be present in their secretions and excretions. In this context, once a pet dog comes into contact with a sick dog, or there is a common diet, there will be a great risk of illness. Secondly, although parvovirus is harmless to humans, humans can be used as mechanical transmission vectors. If people do not clean and disinfect themselves well after coming into contact with pet dogs or stray dogs suffering from parvovirus, they may also carry the pathogen into their homes, thereby posing a hidden danger of pet dogs becoming infected and sick. Thirdly, flies, mosquitoes, lice and other insects can also be carriers of parvovirus. Finally, when a pet dog's immunity declines, its susceptibility to parvovirus disease will significantly increase. In breeding practice, factors that lead to low immunity in pet dogs involve many aspects, such as changes in environmental temperature, poor diet quality, stress reactions, and failure to perform immunizations.

Clinical symptoms

After pet dogs suffer from parvovirus disease, there are two main types of symptoms: enteritis type and myocarditis type. If the pet dog suffers from enteritis type disease, it will have symptoms such as elevated body temperature, lethargy, loss of appetite, diarrhea and vomiting in the early stages of the disease. Usually, the early vomitus of sick dogs is mainly food. After the stomach contents are basically emptied, the vomitus of sick dogs will turn into yellow or yellow-green digestive juice.

After this, as the course of the disease prolongs and the condition worsens, the sick dogs will develop symptoms of malnutrition such as body weight loss and sunken eye sockets, and some dogs may suffer from disturbances of consciousness. At the same time, the sick dogs' diarrhea intensified, and their excrement mostly changed from porridge-like loose stools to sticky bloody stools, accompanied by an obvious fishy smell. If a sick dog has frequent diarrhea, its anemia will become more serious. If the disease suffered by pet dogs is myocarditis type, it will show the characteristics of rapid onset and short course. The sick dogs will often die within a few hours, and the cure rate is extremely low. In the early stages of the disease, there are usually no obvious changes in the mental state and eating behavior of sick dogs. A small number of sick dogs have symptoms of a slight increase in body temperature and mild diarrhea. In the following tens minutes or hours, the symptoms of the disease in the sick dog will gradually become obvious, and symptoms such as difficulty breathing, rapid heartbeat, and irregular heartbeat will appear until death. Myocarditis-type parvovirus disease mainly occurs in young pet dogs under 2 months old, mostly in small and large dogs, and the fatality rate is as high as 80%.

Comprehensive prevention and control measures

(1) Do a good job in raising and managing pet dogs

In providing healthy survival for pet dogs environment and high-quality dietary resources, while blocking the transmission routes of parvovirus as much as possible. First, we must strictly control the feeding quality of dog food, canine snacks and nutritional supplements to ensure that pet dogs always have a balanced and sufficient nutritional intake, laying a solid foundation for the development and operation of their immune systems. Second, it is necessary to minimize the stress sources of pet dogs, such as preventing pet dogs from being frightened, maintaining a constant temperature in the breeding environment, etc. to prevent pet dogs from increasing the probability of illness due to stress reactions. Third, indoor cleaning, ventilation, disinfection, insecticide, etc. must be done regularly to prevent parvovirus from breeding or spreading in the daily activity areas of pet dogs. Fourth, after raising a pet dog, you should try to avoid contact with other pet dogs or stray dogs, and do a good job in managing and protecting the pet dog while walking. Only in this way can the contact between pet dogs and parvovirus be avoided to the greatest extent.

(2) Implementing the vaccination program is the key to dealing with animal diseases

When vaccinating pet dogs against this disease, the first vaccination time should be selected when the pet dog is 45 days old Above, it is necessary to ensure that the pet dog is in good health. Thereafter, pet dogs should be vaccinated again every 21 to 28 days. It is appropriate to vaccinate three times in the first year. In addition, in order to prevent pet dogs from being infected with parvovirus to the greatest extent, booster vaccinations should be implemented every November or so starting from the second year to ensure that the immunity of pet dogs is at a high level.

(3) Pay more attention to the dog’s behavioral activities and mental state

Only by paying more attention to pet dogs can early detection and early treatment of parvovirus and parvovirus be ensured. If it is confirmed that the pet dog is suffering from parvovirus disease, it is necessary to promptly use drugs such as ceftriaxone sodium and Dadufenlin for antibacterial and antiviral treatment, so as to alleviate the impact of parvovirus and prevent the occurrence of secondary infection. On this basis, it is also necessary to prescribe the right medicine according to the specific symptoms of the pet dog. For example, if a sick dog has severe symptoms of vomiting, diarrhea, and blood in the stool, it needs to be fed antiemetics, antidiarrheals, and hemostatics, such as methoclopamide, gentamicin, and hemostasis. If the sick dog shows symptoms such as weight loss, food refusal, and dehydration, it needs to be rehydrated with electrolyte solution, saline solution, glucose solution and other drugs to prevent the sick dog from facing the risk of death due to exhaustion, acidosis and other problems.
