I am not sure why you need a whistle incorporated into the buckle, but there it is! I bought these to have reflective material on them all the time without adding a reflective collar. My dogs are short haired so it is easy to see. I wanted the narrower (3/4) band, but only 1" wide is available in size large. My dogs are right between the medium and large so I have to buy large to make sure they will fit.
