Effective dog training does not require many items, but there are a few basic supplies that will help make the process more convenient and effective. Choose a dog collar or harness that is suitable and comfortable for your dog. Then decide which dog leash is best for training. A retractable leash is not appropriate for dog training. You will also need dog training treats that your dog enjoys and are easy to eat quickly so the reward is more immediate. There are plenty of great treats available at pet stores or you can also use something you make at home, like small pieces of plain cooked chicken or turkey.
It’s best not to punish the puppy for making a mistake. Instead, focus on praising appropriate bathroom behavior. If you catch your puppy in the act, interrupt it by saying “No!” in a firm voice or clapping your hands loudly, then take the puppy outside to finish going to the bathroom. Never swat your puppy, yell at it, or try to rub its nose in the mess.
