If you're the type to take your pup with you while you search for agate, quartz, jasper or amethyst, make sure they're looking their best with this Gems & Minerals collar!

Martingale collars are what you need if your dog's head is smaller than its neck – like a greyhound or a whippet, any dog prone to slipping their collar, or dogs with delicate tracheas and necks – like chihuahuas and pomeranians.

Our Martingale collars are available in three sizes, adjustable, and built with rPET webbing (made from recycled soda bottles).
