Astronomy Eco Martingale Collar Size:Small Calculate trajectoriesBring 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.
