Even though your new dog collar 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 collar down from there. The spiked collar will only have 1 1/2″ of adjustment. As an example, the 22" collar will adjust from 22" in the furthest hole, down to 20 1/2" in the first hole. Each hole in this collar adjusts 1/2".

spiked dog collars size guide
  • 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
  • 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.
  • A rule of thumb is to leave an allowance for two fingers to fit between the collar and the dog for a comfortable fit. The collar should not be so tight that it will cause discomfort or so loose that it slides over the dog’s head.

Important Sizing Note: Larger width collars tend to run small. When in doubt, we recommend ordering the next larger size.
