Cocker Spaniel bandana size chart: 15–18 in square

How do I measure a Cocker Spaniel?

1. Stand the dog square. Use a soft tape where a flat collar sits, on the skin, not over the coat.
2. Snug the tape, then leave room for two fingers. That reading is the neck.
3. Add about 8 inches on the long edge for the knot. Pick the smallest square that covers it.
4. Fold corner to corner. The point rests on the chest, and the knot sits at the side or the back.

What fit notes matter for a Cocker Spaniel?

Cut a 15 in square to an 18 in square for a typical adult Cocker Spaniel neck of 12–16 inches where a flat collar sits. The build to expect is a medium neck under long ears and feathering. That interval is a fitting range for adult pets, not a breed-standard measurement and not a reason to skip the tape on the dog in front of you.

A 12 in neck uses the extra small 15 in square (long edge about 21.2 in). A 16 in neck uses the small 18 in square (long edge about 25.5 in). One Cocker Spaniel does not give you the size of the next.

The miss that shows up on a Cocker Spaniel is starting the tape too high toward the ear leather. Stay at the collar line, ahead of the shoulders, on the skin. Weight, a photo, or the size printed on another dog's bandana does not give you the long edge.

Fit the fabric to the anatomy you can feel: a medium neck under long ears and feathering. Fold the square once, corner to corner, and tie the long edge so the point rests on the chest rather than over the eyes or into the water bowl. Two fingers should still slide under the knot after it is snug. If the point drags or the knot pinches a fold of skin, remeasure and recut—do not force a larger square and pull harder.

Measure where a flat collar sits and leave room for two fingers, as in common dog-apparel measuring guidance from the American Kennel Club. Then use this site's square chart rather than a clothing size label.
