Cincy's Mom,

Drake is a different dog in that collar. He is very smart and a quick learner, but likes to test his limits. Not only has the prong collar helped me control his pulling (which he no longer does even with a regular collar), but it has also helped me control his aggressive behavior towards other dogs. We do not need it anymore around other dogs! We still use it on a day to day basis when we practice obedience and other commands. The prong collar was the only way I could teach Drake to heel.
