The prongs used in today's e-collars are a surgical, non-irritating, stainless. If the collar is properly fitted they should not irritate the dog at all...
Most people make the mistake of having the collar too loose. If the collar is able to move around at all on the dogs neck it is too loose and will irritate the skin.
Also, no snug collar should be left on the wet dog to dry. This includes e-collars or nylon regular pet collars. That leads to hot spots on the dogs neck (hot spots are open sores).
If you have an older collar you can cut panty hose (or a thin sock material) and actually place it over the collar and prongs to keep it from irritating the dog.
