Dog adenovirus is an acute disease of young carnivores, characterized by fever, damage to the respiratory system, digestion, conjunctiva and lymphoid tissue.
The disease is common among carnivores of all breeds and ages, but young animals are most susceptible at the age of 2 weeks to 4 months. Dogs of different breeds get sick, but puppies are more sensitive. The source of the causative agent of the infection is sick animals that secrete the pathogen into the environment, when coughing, sneezing, with nasal discharge and feces. Infection occurs through the airborne droplets and the alimentary tract and through the conjunctiva of the eyes, with direct contact.
The incubation period of adenovirus is 5-14 days. The disease usually begins with persistent and prolonged fever, growing cough and sneezing in view of the localization of the primary process in the upper respiratory tract. Then there are serous outflows from the nose and eyes, signs of pharyngitis, bronchitis, conjunctivitis. Some animals develop swelling in the neck, accompanied by minor hemorrhages on the skin. Gastrointestinal upset in the form of diarrhea mixed with blood is registered in puppies. The duration of the disease is from 2–4 to 14 days.
As specific agents, therapeutic immunoglobulin and hyperimmune serum are used. In addition, the use of drugs of pathogenetic, immunostimulating and symptomatic therapy is provided.
