Puppies should be 5 month old or younger when starting the class Since early socialization is key to your dog’s well-being, the HSSC has devised this special class. Drop off your pup for supervised play with other dogs, go do an errand or get a cup of coffee, and then come back forty-five minutes later to pick up your tired, happy pup. What vaccinations are required for a puppy class? - Proof of at least one distemper/parvo combination vaccine at least seven days prior to start of class. - Proof of current rabies vaccination if puppy is over four months. - Proof of current bordetella vaccination. Photo proof of vaccinations must be emailed two days prior to the start of in-person classes or your dog will not be able to attend class. Email to dogtraining@humanesocietysoco.org.
