A comprehensive puppy training schedule involves focusing on basic commands like 'Sit', 'Stay', 'Come', 'Heel', and 'Lay Down' starting as early as when housebreaking begins. These should be mastered one at a time, using consistent phrases and short, positive training sessions of 15-20 minutes, once or twice daily. As the puppy grows, gradually incorporate more advanced skills and socialization practices. It's vital to ensure the training atmosphere is positive, using treats for reinforcement without overindulgence, and adjusting techniques according to the puppy's developmental stages and learning pace.
