This is a heavyweight collar which is very rugged, and the tooling gives it a nice amount of interest. The keeper matches the tooling pattern.

For sizing, place a flexible tape measure around your dog's neck in the place you would like the collar to rest, and pull it to the appropriate snugness, taking note of the measurement. Be careful to avoid fingers under the measuring tape.
If you have a collar that fits well, you may buckle it on the hole your dog is currently using and take a measurement of the INNER circumference, NOT around the outer perimeter of the collar.
