When your dog has mastered the basic commands that you've taught him and is excelling in his obedience training exercises without distractions, it is at this point that you can begin introducing outside distractions to challenge him more. Doing this is a great dog training strategy that will teach him to follow your commands even when there are other things going on around him.
Your ultimate goal is to have your Pit Bull obey your commands regardless of location or environment. As your dog progresses in his training, you’ll be able to give him a command in the middle of a crowded area and he’ll obey you. This is an important thing for not only his safety, but the safety of other people and animals as well. Having a well-trained dog can eliminate many of the horror stories you hear related to owning a dog.
You should also learn to prevent your dog’s mistakes by learning what makes him falter. For example, if you’ve given the sit stay command to your Pit and he starts to get up, correct him immediately so he learns. You’ll definitely know when he is getting ready to break the command by the signs he gives. He may bite or lick his paw, act uneasy and figity, etc. Whatever your dog does when his attention is beginning to stray, recognize it and work on regaining his attention.
