A position statement on early socialization in puppies released in by the American Veterinary Society of Animal Behavior encourages veterinarians to recommend puppies be socialized before the vaccine series is complete.

The guidelines state puppies can start socialization classes as early as 7 to 8 weeks of age. In general, they should receive a minimum of one set of vaccines at least seven days prior to the first class as well as a first deworming.

Additionally, puppies should show no signs of illness during the classes and should be kept up-to-date on vaccines throughout the class.

While veterinarians are appropriately concerned about infectious disease in young puppies, the fact is that behavioral issues—not infectious diseases—are the number one cause of death for dogs under 3 years of age, according to the AVSAB. Veterinarians contribute to these behavioral issues when recommending pets be kept away from possible germs until their vaccine series is complete, the AVSAB stated.

“Puppies go through a sensitive period of socialization when they are uniquely prepared to benefit from exposure to social opportunities. From the time the owner adopts the puppy until 3 to 4 months of age, it is critical that the owner get the puppy out to meet other animals and people, and experience many different kinds of environments,” said AVSAB president, Dr. E. Kathryn Meyer.
