All of our collars (unless otherwise noted on the product page) are measured to the center hole for a true neck size or will list the neck size range that the collar will fit.
The measurement of your dog’s neck is the size of the collar it needs. No guesswork needed to buy a collar that fits your dog correctly and comfortably.For example, if you measure your dog’s neck and get 16”, you should pick a 16” collar OR a collar where 16” is comfortably within the size range.
Each collar will have adjustment holes above and below the middle one, so you will also get 1-2 inches of extra adjustment in either direction.
Simply measure your dog’s neck for the proper collar size. There should always be enough room between the pet’s neck and the collar to slip one finger between them comfortably. This ensures that the collar isn't too tight
Here are a few different methods for measuring your dog's neck:
Measure your dog's neck with a sewing tape.
Wrap a string around your dogs neck. Mark the string and then measure the length of it with a ruler or tape measure.
Remove your dog's current collar and stretch it out flat. Then measure from the center of the buckle to the current sizing hole or adjustment being used.
