Puppy obedience training is important for a puppy's development and satisfaction of needs. Puppies as young as 7-8 weeks can be trained if owners provide leadership, guidance, and things for the puppy to focus on. Key tips for training an obedient puppy include supervising the puppy, socializing it at a controlled pace, getting it used to new people and environments, handling its body, using rewards, and using hand signals along with verbal commands. Regular short training sessions are important as puppies have short attention spans, and an obedient puppy will feel safe and be a delight to be around.
