I got "collar tags" for mine and you can fit them on a harness. Mine little ones don't wear collars either and when they go outside they have their harness on. They actually lay flat on the webbing of the harness. I absolutely love these. All my dogs have them. Here's the link if anyone wants to look. Pet tags, dog tags, pet id tags, dog id tags, pet identification tags, cat id tags.
