All collars are 1" wide and are adjustable.
Martingale collars have no buckle at all, and tighten a bit when the dog pulls. If adjusted properly, the dog should not be able to back out of it.
Metal buckle collars have super sturdy, anodized aluminum buckles that will not rust.
Does your dog scratch a lot? If so, please consider a collar made from patterned polyester webbing. This material will better hold up to sharp nails and scratching, which is likely to damage the decorative ribbon found on most collars.
