Best Dog Collar for a Cavalier King Charles Spaniel: Size, Fit, and Style Guide

Cavaliers are small spaniels with a fine neck. Measure to the skin beneath the feathering.

The number on the size chart only works if you measure first. Wrap a soft tape measure or a piece of string around the base of your Cavalier King Charles Spaniel's neck, where the collar naturally sits, then keep it snug but not tight. The gold standard is the two-finger rule: you should be able to slip two fingers between the collar and the neck once it is buckled. For the full walkthrough see our dog collar size chart, or let our sizing calculator do the math for you.

Cavaliers have a fine, fairly delicate neck, so a lightweight collar at a gentle two-finger fit is the comfortable choice. The feathered coat around the neck and ears can add a little apparent bulk, so part it and measure to the skin so the collar is not secretly loose.

Make sure the collar sits at the base of the neck rather than riding up into that long ear feathering, where it can mat the coat. A soft, smooth webbing is kindest to the feathering and easy to keep clean.

A pretty floral suits a Cavalier's elegant, old-fashioned charm. A soft look like our Garden Party collar complements their rich coat colors. Browse the rest of the Dazey collars for more small-dog styles.
