If you have a puppy between 2-5 months old, sign up for the 2-5 month class. If you have a puppy 5-9 months old, sign up for 5-9 month puppy class. If your dog’s age is on the cusp of either class, please sign up based on breed size. Smaller dog breeds, please sign up for 2-5 month class. Larger dog breeds sign up for 5-9 month class. Both classes teach the same criteria but we’re keeping dogs in similar developmental stages together. Your next class after completing puppy class will be Obedience 1.
