how many times do puppies need shots
Most veterinarians recommend that a puppy receive his first parvovirus vaccination when he is 8 weeks old. The second vaccination is given in three to four weeks, about age 11 to 12 weeks. A third vaccination is given in three to four more weeks, about age 14 to 15 weeks. A vaccination is sometimes given three to four weeks later, about age 17 to 18 weeks. Most all veterinarians agree the final vaccination in the series should be given after the puppy is 4 months old.
