Dog Size Charts for Harnesses & Collars

Harness Sizing

To measure a dog for a harness, find the largest part of torso behind the front legs.


Collar Sizing

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

  • 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.
