How to properly determine size:
To find the right size collar, you will need TWO measurements
1) Neck circumference,use a soft tape measure or piece of string and wrap it snugly around the base of your dog’s neck--snug enough so that you cannot fit any fingers under the measuring tape.
2) The size in inches from the neck to the snout
If any of the measurements are 'between' two sizes, choose the larger size.
