Who is it for?

This Large collar suits dogs with bigger necks and active lifestyles — think retrievers, shepherds, boxers, and similar breeds. If your dog sits between sizes, we also carry the Ashario Pets - Reflective Adjustable Nylon Dog Collar - Medium and the Ashario Pets - Reflective Adjustable Nylon Dog Collar - Small for a more tailored fit.

How should the collar fit?

Adjust the collar so you can slide two fingers flat between the webbing and your dog's neck — snug enough that it won't slip over the ears, loose enough to avoid rubbing. Check the fit regularly, especially after coat changes.

Feeding & use

For everyday wear, walking, and leash training, clip your leash to the reinforced D-ring and confirm the quick-release buckle is fully seated before heading out. Inspect the stitching, buckle, and D-ring periodically for wear, and rinse the nylon with mild soap and water when it gets muddy.

For a smaller puppy joining the family, the Ashario Pets - Reflective Adjustable Nylon Dog Collar - Extra Small works well as a lightweight first collar. Whether you're buying collars online for a growing pack or adding to a wider order of dog supplies online, this is a straightforward, durable pick when you buy collars and co.
