reusable dog diapers size Medium (Derwood, MD)

I have 3 washable/reusable diapers for female dogs in size Medium, but they are different brands so please see size information below and tell me which one(s) you want.
• One Paw-Inspired hot pink diaper, size Medium is for waist size 16-21 inches: https://www.chewy.com/paw-inspired-washable-female-dog/dp/235135
• Two Wegreeco diapers, one in hot pink and one in turquoise, size Medium doesn’t give waist size but it looks a little smaller than the Paw-Inspired diaper and the size given for another style of Wegreeco diaper is waist 12-15 inches (probably the same for these diapers)
