The onset of ejaculation and development of normal seminal characteristics in six young dogs vaccinated and seroconverting against canine parvovirus did not differ from the accepted range, and by 45 weeks of age the ejaculates were considered to be normal. At one year of age three of the dogs were given a large antigenic stimulus by vaccination once a week for four weeks; this produced no change in the output or characteristics of spermatozoa.
