How long do dogs have herpes?

The minimum period of illness for a dog with herpes is about 15 days. The duration of the disease varies depending on the age of the affected dog and the dog’s immunity, but the shortest period is about 10 to 15 days with significant improvement, depending on the owner’s route of administration and treatment and the dog’s immunity. Canine herpesvirus infection can cause a variety of forms of disease. Newborn puppies are often lethally infected and dogs older than 21 days of age show mainly upper respiratory signs. It can also cause infertility, abortion and stillbirth in female dogs, as well as penile and prepuce infections in male dogs. In adult female dogs, infection of the genital tract is the main cause, with diffuse vesicular lesions of the vaginal mucosa, which can cause abortion, stillbirth and infertility in pregnant bitches. In male dogs, chronic inflammation of the penis and foreskin can be seen, and there can be a large amount of purulent discharge from the foreskin.
