How to diagnose spay incontinence in female dogs
Observe when your dog is leaking urine.
Spay incontinence occurs when a female dog is lying down to rest or sleep. The urine may leak in small spurts, rather than continuously.
When your dog is resting or sleeping, look for a urine puddle or damp spot start near your dog's back end. Lying down puts pressure on your dog's bladder.
