I'm sorry, but I do not agree with using prong collars at all. Nor do I agree with choke chains. These are all just band-aids to the real training problem, using pain to subordinate your dog. To me, if some one absolutely needs a prong collar to control their dog, they have little to no control over that dog. What if the dog does manage to escape the collar? Will they be long gone? probably.

I know people who show their dogs, and use very fine choke chains adjusted correctly at the neck, which I'm passive about. They also only use these collars during shows, not during liesurely walks, because their dogs have been properly trained. 99% of the dogs I see being walked with choke chains and prong collars, are not fitted even close to correctly, and the dogs are still constantly looking for a reason/moment to yank their owners arm off (because the dog lacks training and, despite the painful collar they're wearing, in their minds they are still the alpha). Most people I see with dogs wearing choke chains and constantly tightening the chain, which is completely wrong. If choke chains are going to be used, you should only need to give a slight jerk every now and to remind the dog to heel. Again, training will solve these problems, but in today's society everyone wants an automatic fix.

What I use in replacement of a choke chain, is just a rolled leather collar fitted correctly at his neck. It doesn't tighten, restrict, or damage anything, but it won't slip off and its perfect for leash training. ALL of the awesome, credited, educated dog trainers I've met suggest this, and will not accept dogs into class with chokers, prongs, or haltis ^^
