[Rottie Mann]

I have mine fitted so i can get one finger under the prongs while the collar is fully expanded.

I can twist the collar around on my boys neck, but it will not freely twist on its own.

If you can slip it over your dogs entire head, then I would think it is WAYYY too loose.

I think it is best to hook the lead up to one ring only (the swivel one)......works much better that way........for me anyway.
