Understanding Adenovirus in Dogs: Symptoms, Prevention, and Treatment

Adenovirus, a term that may sound complex, can significantly impact our beloved canine companions. In this informative article, we will delve into the world of adenovirus in dogs, specifically focusing on Adenovirus type 1 (CAV-1) and Adenovirus type 2.

What is Adenovirus in Dogs?

Adenovirus type 1 (CAV-1), also known as Canine Adenovirus 1, is responsible for a condition known as Infectious Canine Hepatitis. This viral infection primarily affects the liver and can cause various symptoms in dogs. Adenovirus type 2, on the other hand, is associated with Canine Respiratory Disease Complex (CRD).

Preventing Adenovirus in Dogs

Vaccination is Key

Vaccination plays a pivotal role in protecting dogs from adenovirus infections. A combination vaccine, DHLPP, which includes protection against Distemper, Hepatitis (CAV-1), Leptospirosis, Parvovirus, and Parainfluenza, is recommended.
