Many breeders recommend training puppies after completing their vaccine series. However, dog experts recommend one should enroll their puppy in private dog training classes as soon as they get home. According to the American Veterinary Society of Animal Behavior’s Position Statement, the best time to enroll him in a puppy class is during his developmental stage, ages 6 to 16 weeks. Enrolling your puppies in puppy socialization classes would be ideal for helping them explore new locations, dogs, cats, and people. The puppy class would also benefit your puppy when he gets to the adolescent stage between the ages of 8 to 18 months to keep him happy and friendly.
