Freshwater Fish Eco Martingale Collar Size_1" | 25 mm circle A leafy green notebook filledThis Freshwater Fish pet collar is ready for those creekside hikes and riparian adventure photos. 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).
