Collar Sizing


Follow the steps below to ensure that you get the perfect sized collar for your pup!

Option 1- Measure your pup’s neck:

  • Measure your dog’s neck by using a cloth or sewing tape measure, string, or flexible object.
  • Take your measuring object and wrap it around your dog’s neck where your dog normally wears their collar. Make sure it isn’t too tight, you should be able to get a finger or two under the collar. If using a string or other flexible object, use it to determine the size around your dog’s neck, and then measure that length on a ruler or tape measure.
  • Find the perfect collar size below using those measurements. If the measurement falls between the sizes, and your dog is still growing, consider going up in size. Be sure to enter the measurement in inches when checking out!

Option 2 - Measure an existing collar that fits well:

  • Find a collar that fits your dog well
  • Take it off your dog and lay it flat.
  • Lay the collar next to a ruler. DO NOT MEASURE END TO END. - For buckle style, measure from the buckle fold to the hole your dog is using on the collar. - For clip style collars, only measure one side of the clip.
  • Find the perfect collar size below using those measurements. If the measurement falls between the sizes, and your dog is still growing, consider going up in size. Be sure to enter the measurement in inches when checking out!
