Perfect for more difficult to handle dogs or for those that have a tendency to slip out of their collars.  Designed for dogs over 40 lbs. – english bridle leather available in several colors – linings available in a rainbow of hues – hardware available in brass or steel Important Note: Brass martingale chains can cause discoloration to the coats of lightly colored dogs.  This is caused by the friction of the chain rubbing against the O-rings that are attached to the collar. Unfortunately, there’s not much that can be done to discourage this so we’d recommend choosing the Stainless Steel option if staining is a concern. Be advised that martingale collars are designed mainly to help control your dog while walking and should not be worn  24-7. ↓ Scroll down to the bottom of page for info on sizing, returns, shipping and color charts ↓
