Our pug, Oliver, has experienced incontinence issues for several years. We found the SnuggEase reusable pet diapers and can’t say enough about them. We have at least a dozen on hand and they last a long time. I have found that using a feminine pad inside the lining will make the diaper last longer between laundering. My preferred brand is from Walgreens because they are extra large and fit perfectly. Here is a link to the diapers and feminine napkin.
