As Logan said, I was referring to the danger of leaving the choke collar on with the dog unattended! So many stories of accidental choking. Star would have never learned to heel or walk nicely on a lead without the use of one in her obedience class. Now she doesn't need it at all. I think we had a long discussion about choke collars recently. People's opinions do vary! But I think, if used properly, i.e. a gentle "corrective jerk" they are a great training aide.
