I used these in the last 2 months of my 15 pound Parson Russell Terrier’s life. He was our beautiful senior rescue that did go peacefully with has rescue sister by his side. I want to pass them on to another precious pup (or puppy) in need. They work so well by keeping the paper diaper on, especially when you have a determined terrier who wants that diaper off! They are not diapers, just a cover that goes over the diaper to hold it in place. Maybe they were a little big on my boy but I couldn’t sand to see him uncomfortable. They did work for him but would work on a heavier dog. I have washed them several times and they are clean and ready for your sweet pup. Message me with any questions or if you need any more pictures. Thank you for looking!
