Astronomy Eco Martingale Collar Material_rPET 5 mm ink cartridgesBring the stars a little closer to your out of this world fuzzy friend. 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).
