I purchased this for my 17-year-old dog (a Shiba Inu mix) when she started having more accidents. I tried it on her once, but it seemed a little big. I contacted the seller, and they kindly sent me suspenders to try. Soon after, she went back to urinating outside, and there were no more accidents in the house. I no longer needed the diapers. The suspenders are unopened, and I haven't used the diapers since. I have washed them, but some fine hairs remain on the Velcro parts. My Shiba Inu sheds a lot... ^^; I apologize. Other than that, I don't see any stains or anything. I would appreciate it if you could understand this point. Thank you.
