Birds Eco Martingale Collar Discipline_engineeringCarbon Neutral This kingfisher looks equally atHere's the perfect collar for your fuzzy friend who loves birds as much as you. 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).
