How it Works: Quick, properly timed collar correction, scruff shake, alpha roll or tap on chest can teach your dog NOT to do whatever he is doing at that exact moment.
Comparable To: Grabbing a person's arm and saying, "Don't do it".
Recommended For: When your dog is pulling on the leash, collar corrections should be used. If done properly, you should only need to do it a few times. Otherwise, your dog is not getting the message and you should consult a trainer. Physical corrections can also be used to stop bad behavior while it is occurring but, again, they must be timed perfectly.
Caution: Some dogs respond to violence with more violence (aggressive) or get scared and lose confidence (fearful). Consult a professional trainer to learn how, when, and if you should use these corrections on your dog.
