1st hole is at 19.5", last hole is about 23".
Very nice collar, good for larger breeds like Large Labs, German Shepherds or Pit Bulls, other larger breed dogs.
This one is used but not very much. It's in like new condition.
Asking a donation of some sort to A Paw Up Rescue and we will ship it to you
