FancyNancys Dog Diapers, Panties, Britches just for Whippets - Pants for Whippets. Our size Medium Whippet washable dog diapers are a perfect solution for dogs and puppies working on house breaking, dogs in season, dogs in heat, senior dogs, dogs with incontinence, leaking urine and excitable urination. Our washable dog diapers will need a disposable liner or sanitary napkin (designed for women) inside the diaper to prevent the diaper from getting soiled. For incontinent dogs who pee rather than dribble you will need either a disposable baby diaper, sanitary pad or an incontinence pad. Please help us get your order "right", by ALWAYS providing us with the following accurate information for dog diapers: breed, weight, waist measurement, male/female, female season, incontinence, suspender measurement (if ordered) and anything else you think would help us make the perfect dog diaper for your special family member.
