The Food and Drug Administration recently gave its stamp of approval to Incurin, a drug to treat urinary incontinence resulting from the spaying of female dogs. It can also be used for incontinence due to estrogen depletion.
Hormone-related urinary incontinence is a very common problem in adult and senior female dogs that have been spayed. The problem can arise months or years after the procedure.
Typically these dogs urinate normally, but there is urine leakage during rest. Blood and urine tests are usually normal in these pets.
Incurin, manufactured by Merck Animal Health, increases the resting muscle tone of the urethra. According to Veterinary Practice News:
In a study of 226 spayed female dogs, a greater percentage of dogs treated with Incurin improved compared to dogs treated with placebo. Incurin was shown to be effective for the control of estrogen-responsive urinary incontinence in spayed female dogs 1 year and older.
