There are new halters for dogs that can be especially helpful for gaining control gently. We wouldn't think of trying to lead a horse around by the neck, but that's what we do with dogs. Individualize your training to suit your dog's temperament. Breeds and individual dogs differ widely in their interest in and responses to training and handling. Adapt the intensity and timing of your corrections and praise accordingly.
Terriers require lightening-quick responses.
Hounds welcome extra enthusiasm. Notice what kind of activity your dog especially loves, such as playing ball or going for a walk, and use that as a reward. Use repeated cues to help get your point across. To praise your dog, speak in a varied and interesting voice, petting him and showing your affection. To discourage undesired behavior, give timely corrections with a leash and use a no-nonsense tone of voice.
