I train dogs with prong collars. There are very few dogs that I would not train with a prong collar. I recommend them to new dog owners, new trainers and people who own dogs with behavioral problems. While some think a prong looks nasty the fact is they are far more humane than a normal choke collar.
The biggest problem with prong collars is that new dog owners don't know how to put them on, how to size them or how to have their dog wear them. This article will address these issues.
Normal choke collars need to be ordered by length (i.e. 22 inches long etc.) Prong collars are ordered by size (small, medium, large or extra large). They all come in a standard length which is adjusted to fit the neck of the dog by removing or adding links to the collar.
are meant to be put on and taken off before and after daily training sessions. Unlike a choke collar that is often left on the dog all the time (in some cases this can be a dangerous practice).
A common problem new trainers have is they don't remove enough links to get the correct snug fit. When that happens the collar hangs down on the dogs neck which results in the collar not working the way that it was designed. A prong collar should fit the way you see it in the photo below.

The correct position for a prong collar is to sit right behind the ears and up under the jaw line like you see in the photo above. The photo below shows how many people mistakenly let a dog wear a prong.
