There is only one reason why a dog can get canine distemper, which is to be infected by the canine distemper virus. It is not directly related to improper feeding, environmental changes, catching cold and other factors. Canine distemper virus starts from the mutation of cells in dogs and uses the canine body as a carrier to infect. It is an acute febrile infectious disease that mainly harms dogs and canine carnivores. Its incubation period is 3-5 days, that is to say Dogs that do not have enough canine distemper virus antibodies in their bodies can detect canine distemper 3 to 5 days after being exposed to the virus. The first method is that the dog is directly exposed to the sick dog, and the second is that the owner comes into contact with the secretions of the sick dog. If you touch your dog again, you may cause your dog to contract canine distemper.

Symptoms of canine distemper:

1. Respiratory symptoms: cough, purulent nasal discharge, purulent eye droppings, bronchitis, pneumonia, etc. The canine distemper virus attacks the respiratory system and lodges in the respiratory epithelial cells. Bacteria that exist in the environment or in the dog's body but are not normally infected can take advantage of the situation and enter, causing the above symptoms.

2. Gastrointestinal symptoms: vomiting, diarrhea, etc. Theoretically, canine distemper virus can cause digestive tract symptoms, but most of the time, vomiting and diarrhea during canine distemper are not caused by canine distemper virus, but due to intestinal parasites, intestinal anaerobic bacterial infection, and hypoalbuminemia. and other reasons.

3. Nervous symptoms: myotic spasm, epilepsy, empty chewing, encephalitis, paresis, paralysis, masticatory myositis, etc. The appearance of neurological symptoms is somewhat random.
