Ray Allen collars are widely used by trainers and active dog owners who want a rugged, waterproof, low-maintenance alternative to leather.

To ensure the best fit, measure your dog’s neck before selecting a collar size.

How to Measure

Use a soft measuring tape.

Wrap it around your dog’s neck where the collar will sit (typically high on the neck, just behind the ears).

Pull the tape snug, but not tight. You should be able to fit two fingers between the tape and your dog’s neck.

Use this measurement to choose the appropriate collar size.

How Ray Allen Collar Sizing Works

These collars feature 7 adjustment holes spaced approximately 1 inch apart.

The listed collar size corresponds to the largest neck measurement (last hole).

This provides several inches of adjustment for a secure fit.

20" Collar – Fits approx. 14"–20" necks

22" Collar – Fits approx. 16"–22" necks

24" Collar – Fits approx. 18"–24" necks

Sizing Tip

If your dog’s neck measurement falls between sizes, choose the size where your measurement falls toward the middle of the adjustment range for the best fit and flexibility.

Example:

A dog with a 19" neck will fit best in the 22" collar, giving room for adjustment.
