If you are not using an everyday collar then what is being used to show their dog license, name tag, rabies vaccination, etc?
My dogs run naked at home. That's safest. When we live the property, on adults, I use a leather buckle collar with deerskin on the inside, from weaver leather for tags. I use a leather martingale for the leash.
For puppies, I usually use a nylon adjustable collar for tags, and a nylon adjustable martingale (quick release if possible) for the leash.
