The Parvovirus vaccine is designed to protect dogs from canine parvovirus, a highly contagious virus that can cause severe gastrointestinal illness. This vaccine is typically administered to puppies starting at six to eight weeks of age, with booster shots given every three to four weeks until they are about 16 weeks old. Adult dogs should receive regular booster vaccinations to maintain immunity. Vaccination is crucial because parvovirus can be life-threatening, especially for young or unvaccinated dogs. Symptoms include vomiting, diarrhea, and lethargy. The Parvovirus vaccine is considered safe and effective, significantly reducing the risk of infection and helping to control outbreaks in dog populations.
