All collars are custom made and will be adjustable. How to measure your pup’s neck size:
Option 1: Measure your dog’s neck using a soft tape measure around the area you like the collar to sit.
Option 2: Use a string if you do not have a soft tape measure, and measure the length of the string.
Option 3: Use a collar that fits them well, unbuckle it and lay it flat, and measure the length from the female end of the buckle to the edge of the fabric (not the other buckle).
