What symptom is canine distemper?

It can be divided into five characteristic types: hyperacute, acute, gastrointestinal symptoms, neurological symptoms and skin symptoms. Clinical symptoms are mainly limited to the upper respiratory tract, so cough, runny nose will be very obvious.

The latent period of canine distemper varied with the source of infection. The incubation period from the same animal is 3-6 days. The incubation period of heterologous animals can be as long as 30-90 days.

The initial infection of CDV begins when the virus invades the epithelial cells of upper respiratory tract. The virus quickly spread to local lymphoid tissues, tonsils, and bronchial lymph nodes. Subsequently, CDV spreads to epithelial tissue and central nervous system in the first week of infection. Humoral immune response after infection is related to virus clearance. Dogs recovering from acute CDV infection are likely to gain immunity for several years. The virus will spread to the skin, exocrine and exocrine glands, digestive tract, respiratory tract and genitourinary tract of infected dogs without effective immunity.

matters needing attention

Some dogs in the course of the onset of canine distemper will be complicated with pyoderma, this symptom occurs in the middle and late stages of the onset of canine distemper or after rehabilitation. At this time, there will be multiple abscesses on the dog's body surface. At first, the abscess site presents induration, and then the induration becomes soft. The skin in the center becomes thin, and presents deep ulceration and pus blood flow. In serious cases, large area ulceration will occur. At this time, we can diagnose the complication of pyoderma.
