A. Length Measure from the base of the neck (where the collar would sit) to the base of the tail along the dogs back.
B. Neck Measure neck circumference.
C. Chest Measure right around the body from behind the front legs around the deepest part of your dog's chest.
Our sizing is smaller than usual, please do the measurements carefully.
Make sure your dog is standing when you take his measurements.
Allow 1/4 to 1/2-inch variance on all your measurements. If a measurement is a fraction of an inch it's usually best to round up to the nearest whole number.
