How to measure a Sighthound for a collar
These instructions apply when measuring a sighthound or other breeds with narrow heads for slip-over and martingale style collars. These instructions do not apply for breeds where the collars are buckled or snapped.
The actual size of the collar is determined by the larger of the "A" and "C" measurements, with the "A" measurement being the absolute minimum size of the collar. The difference between the size and the "B" measurement is used to determine the control loop size on martingale-style collars.
These measurements are best done with a cloth tailors/seamstress' tape measure. Do not use a steel carpentry-type tape measure. If you do not have a cloth tape, cut paper into 1" wide strips and tape together until you have sufficient length (2 pieces are usually enough). When using the paper tape, wrap it around the point you are measuring, and mark where it overlaps. Then lay flat and measure the length to the mark.
When measuring, pull the tape until it lays firmly on the dog's skin, but do not pull tight. You should be able to slip a finger between the tape and the skin.
