To measure for a collar, please use the diagram below as a guide.

Collars come in sizes:- SMALL 11-15"    28-38cm,  STANDARD 14-18"  36-46cm, LARGE 16-20"  41-51cm

These measurments will help you choose the correct collar size ie if A is 14", B is 15" and C is 17"  then Standard would be the size to choose as all these measurements come within the sizing.

You can use either a soft tape measure, or if you don't have one a non-stretchy piece of string and a ruler will do.
