Some facts about Canine Urinary Incontinence

Urinary incontinence is most commonly caused by urethral sphincter incompetence. It is most common in large breed, spayed female dogs (11-20% incontinence). Estradol-171β concentrations decrease after ovario­hysterectomy in bitches, resulting in deterioration of urethral closure within 3-6 months. Registered for use in male and female dogs.
