Sizing:
S: 8.5" - 11.5" , 21.5cm - 29cm
L: 10" - 13" ; 25cm - 33cm
*Please note that the sizes do not mean that they fit up to that length of neck. We measure our collars fully extended and fully contracted. You want to add approximarely 1" - 2" to your dogs/ cats' neck measurement and then select a size where that measurement falls in the middle.
Example: Dogs neck measured at 10", add 1" - 2" to that measurement (11"-12"), select a size large.
