The Parvovirus Vaccine is a core vaccination, meaning all dogs should be protected against the Parvovirus disease regardless of their lifestyle. You can choose to protect your dog from Parvovirus disease with a combination vaccination (DA2PP) or it can also be administered separately. Dogs as young as six weeks old can receive the vaccine. This vaccination is initially administered in a 2-part series, with vaccinations administered 2-4 weeks apart. In young puppies, additional boosters may be necessary. Parvovirus is highly contagious, so annual vaccinations are recommended to protect your pet
