If you've ever witnessed a puppy suffering with and probably dying from canine parvovirus, you want to ensure no dog of yours ever goes through such a nightmare. Fortunately, vaccinating your puppy against parvo in a timely manner and on the right schedule can prevent him from contracting this highly infectious gastrointestinal disease. The parvovirus vaccine is given in combination with distemper, parainfluenza, hepatitis and leptospirosis.
How Often Do Dogs Need the Parvo Vaccine?
Puppies usually receive their first combination vaccine between the ages of 6 to 8 weeks, with two boosters each given four weeks apart. That means the puppy vaccines are finished between the ages of 16 and 20 weeks. One year later, your now grown dog receives another booster. After that, he should be vaccinated again every three years. If a dog over 4 months of age receives his first shot, he receives a second booster in another three to four weeks. He receives another shot one year later and then goes on to the three-year schedule.
