Accessorize your pup for your next mushroom foraging adventure, or coordinate their daily look with your mycology research!

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).
