Ocean Science Eco Martingale Collar Size_24" x 36" Whether you're an agricultural scientistHere's the perfect collar for dogs who love beach days as much as you do! 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).
