All dogs are different and vary in their size, just as people vary in size and shape. Here is a general guideline to fit your dog appropriately for a dog collar. For a proper fit, measure your dog's neck with a cloth seamstress's tape measure.

  • Take a measurement a few inches down from his head and then add an inch for very small dogs or two inches for medium and large dogs. (#1)
  • Pull the tape snug but not tight. (If you do not have a tape measure, you can use a piece of string and then measure the string with a rigid ruler.)
  • Allow sufficient room to slip two fingers between the collar and the dog's neck. Or you can measure his neck and add two inches.
  • When the collar is on his neck it should allow you to slide two fingers under a properly fitting collar and your dog's neck. If there's extra room, you need a smaller size. If both fingers don't fit, the collar is too small.

If ordering a Martingale or a Tag collar, be sure to also measure at point #2 in the image above to make sure the size you select fits within the range of these two measurements.

A collar shouldn't be tight around your dog's neck and therefore it will not be the exact measurement of your dog's neck. For safety reasons - so it doesn't snag on something, it shouldn't be too loose either. A snug fit is what you are aiming for and not a tight one or one that chokes. Always monitor your furry little friend while he or she is on their leash with a collar, so they don't get caught on a fence or other environmental object that would cause furry friend choking.
