Yes!  If your dog has a very broad head or neck, you may need to weave the cheek tabs back to the second or third slot (vs. fourth) to help ensure a proper fit. If you do need to change the position of the cheek tab, it is advised to use a piece of duct type tape on the outside of the tab for added strength especially for large active dogs. The cheek tabs must be put through at least TWO of the existing slots and should always end on the OUTSIDE.
