This fun blue collar features a chemistry design that's perfect for a chemist's best 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).
