Symptoms of Canine Herpesvirus Infection: Quick Guide

Susceptible Animals:

This virus exclusively affects dogs, with puppies aged 2 weeks being the most susceptible and experiencing a high mortality rate. Adult dogs infected with the virus typically show no clinical symptoms. Infected puppies and recovered dogs are the primary sources of transmission. Puppies are primarily infected through contact with the infected mother's birth canal or postbirth contact, and recovered dogs can carry the virus for an extended period.

Primary Symptoms by Age Group:

Newborn puppies infected with the virus often exhibit no symptoms and die quickly. Puppies younger than 2 weeks may show symptoms such as elevated body temperature, loss of appetite, difficulty breathing, vomiting, abdominal pain, yellowishgreen feces, and crying. Most of these puppies die within a day. Some puppies that survive may develop后遗症, such as ataxia, circular movements, or blindness.

Puppies between 2 and 5 weeks old, as well as adult dogs, may experience symptoms like sneezing, dry cough, and increased nasal discharge, which usually resolves within two weeks. In female dogs, there may be abortion and reproductive disorders, while in male dogs, there can be penile and balanoposthitis.

Prevention and Treatment:

There is no effective vaccine for this disease. Strengthening animal husbandry practices, regular disinfection, and preventing contact with dogs from outside are effective preventive measures. Puppies can also obtain maternal antibodies through colostrum. In cases of illness, treatment for young puppies may not be timely. Oral administration of a 5% glucose solution can help prevent dehydration and alleviate symptoms.
