If you order this pinch collar with the nylon protector right away, you get it of the same size with the collar. No need to measure the collar and adjust the cover by yourself.

In case you ordered a pinch collar, removed several links, and now want to get a nylon cover for it, you can make your nylon protector fit your pinch collar this way:

1. Measure the length of your pinch collar.
2. Measure your nylon protector.
3. Cut extra length of protector and scorch along the edges with the lighter.

In case your dog has grown and you need to add extra links, you can get a new custom-made nylon protector that will fit your pinch collar:

1. Specify the collar size in the dropdown box at the top of the page.
2. Choose how many links you’ve added to the standard collar size.
