Dog collars and harnesses — fit guide

Use a soft tape to measure neck girth for collars and chest girth for harnesses. Leave room for two fingers. Match hardware and width to your dog’s size and activity.

Collar or harness?

Collars work for ID tags and calm walkers. Harnesses distribute pressure across the chest and can help with pulling when fitted correctly. For night walks, LED/USB collars add visibility — check battery and waterproof notes on the product page.

Sizing tips

Always use the size chart on the product. If your dog is between sizes, many owners size up for harnesses and confirm the neck range for collars. Adjustable straps help fine-tune fit.
