“Careful of size”

“The product is fine and would be good to locate your dog in the dark. My little Yorkie weighs 4 pounds and wears a size small or Xsmall. I ordered a size small and it would fit a 20 lb dog. Also the tag said size small/medium although I ordered a size small. There is a huge difference. I still want something like this for my little one for safety reasons. I have to keep my eye on her at all times because of the owls, hawks, coyotes. I do not let her out at night but , you never know...If it fit I would keep it.”
