Heavy Duty Beta Material Dog Collars. Made with quality in Canada. Designed for comfort, but simple to adjust and position. Long lasting nickle plated hardware. Collars are measured to center adjustment, therefore allowing you to adjust bigger or smaller as needed. For example; if your dog measures 16" around neck, you'd be good with a 16" collar. Collars are 1" inch wide unless differently specified. Feel free to contact us via the Ebay store to request alterations or customization. We have more colours of material, different material, different widths of material, different finishes of hardware and also different styles of hardware. Prices subject to change with any alterations.
