How to measure head and neck.

★MEASURING★
Please include the exact measurement of your dog's neck where his/her collar normally rests. Please DO NOT use your pet's current collar size as your measurement. 
For martingale and slip collars measure head right in front of ears, on the widest part of skull. 
Measurements should be taken using a soft/cloth tape (typically used for fabric). Tape should be held snug around your pet's neck or head while measuring.
