Dominant Dog Collar Sizing Guide
If your dog's measurement falls between two sizes, round down to the next smaller size. Do not add any extra length to the measurement for slack. If a collar is too big it will not be as effective for training. A properly fit collar will remain in place behind the ears and not slide down the neck.
Collar Length Measurement
Collars may shrink slighty after sewing and should be pulled gently from either end to expand them to their full length before measuring.
