DOG SLIP CHAIN COLLAR SIZING GUIDE
Please use a soft measuring tape to measure the circumference of your dog's neck and the widest part of the head. Order a chain collar size 2-3" larger than the widest measurement of head or neck. This will allow for the chain to be slipped through to the correct measurement and allow some length for tightening corrections.
Once slipped through, the chain will be 1" shorter around than the size ordered. For example, a 22" slip chain will measure 21" around once slipped through.
