Use a soft tape measure and measure the largest part of your dog’s neck AND the smallest part of the neck (usually right behind the ears).

This dog collar measurement chart illustrates the 3 areas you must measure in order to select the correct size for a martingale collar.

• Measurement A: All the way around the head at the largest point
• Measurement B: Right behind the ears (the smallest part of the neck)
• Measurement C: Where the collar sits

Note:  If you are ordering a Martingale Collar, you will need measurements A, B, and C.  Use the largest measurement to choose the appropriate size.

For Side Release or Buckle Martingale (Combo) collars, you only need measurement C.
