Diaper Garments are the perfect answer for pets with excitable urination or incontinence, female pets in season and puppies not yet quite housebroken. Each garment is lined with a soft plaid flannel fabric for comfort and an absorbent mesh liner for protection from leakage. For light seasonal flow or minor excitable urination the garments may be used alone. For heavy seasonal flow or more serious cases or urination, simply attach a SIMPLE SOLUTION Diaper Garment Pad to product's built-in mesh liner. Machine-wash on gentle cycle. Hang to dry. To insure a proper fit for the anatomy of your male dog, choose the next largest size.
