Urinary incontinence or urinary leaking is a common canine condition with causes ranging from infection to diabetes to abnormal development.  Tests will help determine the seriousness of your dogs problem. There are certain conditions like irritation or inflammation that can cause incontinence. These conditions are easily treatable. Another common cause especially in spayed females dogs and geriatric dogs is a weak bladder sphincter. This condition generally responds well to pet medication so most incontinent pets do not need to suffer.  If your dog is diagnosed with a more serious problem, surgical reconstruction of the lower urinary system will help protect your pet and those expensive carpets! So be patient when slipping on that dog leash and have the paper towels handy.
