Note: Max and Neo's NEO buckle collar (https://www.maxandneo.com/products/the-neo-dog-collar) prints COLLAR LENGTH (XS 8.5-11, S 12-16, M 14.5-19.5, L 17-25 in), not neck size, so it was not used as a neck chart.
If your dog is between two sizes
Max and Neo publishes no between-sizes guidance for the Martingale All Nylon Dog Collar, so this site will not invent one. Between sizes. Check the maker’s chart before you buy.
This site treats a measurement within 1 in of the edge of a size, or inside two sizes at once, as between sizes, and shows both. Work it out with the collar calculator, or read how to measure your dog.

How to measure for this collar
Max and Neo sizes this collar by neck.
Run a soft tape around the widest part of the rib cage, just behind the front legs, and keep it snug but not tight. Two fingers should slide under it. Measure twice: a tape that has slipped an inch is the single most common reason a size is wrong.
A number off this chart is where to start, not a fitting. Measure your dog and check Max and Neo’s own current chart before you buy.
