Braided leather martingale collar with spaced chevron twists are a popular choice. Handmade from soft bullhide leather in 5/8" chocolate brown and cream. Unlike similar collars, ours are hand stitched for extra strength and durability with cream stitching. Made with a 6" 2.5mm chrome martingale chain, 20" closed collar opens to 22.5". Measure your dogs head to make sure 22.5" opening will slip over the head and fit snuggly enough your dog won't slip out of the collar. Bullhide will stretch a little with use.
