CHOOSING THE CORRECT LENGTH:
Measure your dog's actual neck (preferably with a soft tape). Then choose the length that Fits your dog's exact neck measurement. The Length would not be the same as your dog's neck measurement. We have taken into consideration that for a comfortable fit you must allow two fingers (1") to be able to fit between the collar and your dog's neck (no need to add inches for this), so there are adjustments for the exact neck size to fit correctly. If your dog's neck size is an in between measurement always go with the larger size.
*If in doubt please contact us and we will be happy to help: please give us your dog's neck measurement when contacting us.
