Brain Eco Martingale Collar Size:Small Here's a retro-inspired science labA brainy collar for a smart dog! 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).
