Bridle leather is a fantastic leather used in the equestrian trade. This bridle leather dog collar is lined with shearling. The bridle leather makes this collar strong and durable and the shearling lining makes the collar extra comfortable! These collars are especially popular with owners of Greyhounds, Whippets, Afghans, Dobermans and similar large dog breeds! Martingale Collars are appropriate for training, but equally useful as an easy on / easy off collar for everyday use. Made in the USA.
