bathroom and has lost weight. She just dribbles  could this be kidney
stones?  or are we looking at a seriuos and costly
condition?
Thank you very much for your time.

Hi Kathy,

It is fairly common for "mature" spayed dogs to develop urinary incontinence.

Estrogen depletion, resulting from ovary removal during spaying, can cause weakness of the urinary sphincter. Dogs with spay incontinence are best treated with a drug used in the human world for congestion, a compound called phenylpropanolamine. It needs to be given twice a day in most cases, and it works by tightening the urinary sphincter, thereby increasing control. This is considered a very safe drug, though it sometimes has the side effects of increased restlessness and nervousness. These are easily corrected by skipping a dose and starting over at half the original amount.

If the phenylpropanolamine doesn't seem to help, it doesn't rule out hormonally induced incontinence, though. Some dogs do require estrogen replacement therapy. Usually it is possible to use low enough dosages that adverse side effects are unlikely.

It is important for your vet to rule out a bladder infection, bladder stones and diseases that cause increased production of urine, such as diabetes before deciding that incontinence is the cause of urine leakage.

You should have your dog seen by your vet. Bringing a urine sample that is less than 4 hours old can be helpful, just in case it isn't possible to get a urine sample at the vet's office. (you only need about a tablespoon). To collect some urine, place something like a pie pan under your dog when she squats to relive herself.

It would depend on the doctor's findings to label your dog's condition as "serious" or not. Spay incontinence is not considered serious, as it is not life threatening. It does require medical care. Incontinence responds well to treatment.

Good luck, and most importantly, don't get angry with your dog--she probably can't help soiling and is undoubtedly as upset as you are.
