Dog Collar and Harness Sizing Guide

Tips for sizing Collars and Harnesses:

  • Remember that puppies grow quickly, so it is important to check the tightness of your dog collar, harness, or muzzle often.
  • Inspect and replace a collar, harness, or leash as it shows signs of wear.
  • A rule of thumb is to leave an allowance for two fingers to fit between the collar or harness and the dog for a comfortable fit.
  • Dogs, like horses getting fitted with a saddle, may hold their breath while they are getting measured, therefore expanding their chest measurement.
  • If you don't have a tape measure, your can measure your dog's neck or chest with a string then measure the string with a flat ruler.

Buckle Style Dog Collar Sizing Guide

Even though your new dog collar or harness is adjustable, it is important to measure your dog carefully for his comfort and your peace of mind. You will not want the collar so loose that is slips over the dog's head or so tight that he can't breathe properly.

Keep in mind that our measurements are from the center bar of the buckle to the farthest hole and that you will be able to adjust the collars or harness down from there.

Please take into consideration that each collar will have 2" of adjustability. Given the example of a 14" dog collar, a 14" collar will adjust from 12" to 14".

  • Collars: If you are satisfied with the fit of your dog’s current collar, measure that collar from the center bar of the buckle to the farthest hole. Our collars are sized according to this measurement, not to the over-all length of the collar which varies by manufacturer. and by whether it is a buckle-end or a dee-end style collar.

    If this is your dog’s first collar or you need a collar in a different size, measure around the dog’s neck with an allowance for 2 fingers to fit between the dog and the collar. The collar shouldn’t be so tight that it will cause discomfort or so loose that it slides over the dogs head.

 

Martingale Collar Sizing Guide

  • Measure carefully as these collars are sized differently than standard collars.
  • When measuring Martingale Round/Rolled Collars and Martingale Shearling Lined Collars, keep in mind the collar needs to slip over your dog’s head as there is no buckle.
  • First, measure the widest part of your dog’s head. Next, measure your dog’s neck as you would for a standard, buckle-style collar.  Use the larger of the measurements to select a collar that fits between the ranges listed.

Special Recommendations for Round Collars

Our Round Leather Dog Collars are designed to last a lifetime. They are one of the most beautiful and reliable dog collars we offer.

The manufacturing of a Round Leather Dog Collar involves many steps. First the leather is cut into the proper length and width strips. The strips are then formed into the round shapes you see. A leather filler is then stitched into the center of the collar and a buckle and d-ring are riveted in place. This process makes for a collar that will retain its strength, shape, and integrity for years to come. We have provided the following guidelines for your consideration while purchasing a Round Collar that you will enjoy for years to come.

  • As with all of our collars, our measurements are from the center bar of the buckle to the furtherest hole.
