While a prong or "pinch" collar can look like a painful device, when fitted and used properly it can actually be a very safe and effective training tool.
The most important thing is a proper fit. Sizing of the collar is done by adding or removing prongs (links). Be sure to read the instructions that came with the prong collar and follow them exactly.

They are not dangerous unless you use it wrong. I personally don't like them.
