Urinary incontinence in dogs and cats can show up in a variety of ways, and many pet parents first notice subtle changes before accidents become more obvious. Common symptoms include:
- Dribbling urine when a pet is sleeping, resting, or walking
- Damp spots where they’ve been lying
- Frequent licking of the genital area
- Red or irritated skin, or fur staining around the lower belly
- A stronger-than-usual urine odor
- New accidents in an otherwise reliably trained pet
- Urine scalding or sores from ongoing wetness
In dogs, incontinence can be caused by several underlying issues. Some of the most common include:
- Hormone – related changes after spaying, especially low estrogen
- Weakening of the urethral sphincter (USMI)
- Urinary tract infections
- Neurologic issues such as spinal injury or disc disease
- Congenital issues like ectopic ureters, especially in young dogs
- Bladder stones or tumors
- Age-related weakening of bladder or pelvic muscles
Cats experience incontinence less frequently than dogs, but when it occurs, it often relates to deeper medical concerns. Possible causes include:
- Spinal trauma or neurologic disease
- Bladder overstretching from previous urinary blockages
- Inflammation or infection of the urinary tract
- Bladder tumors
- Congenital abnormalities affecting bladder control
And finally, it’s important to note that true urinary incontinence is involuntary — very different from behavioral urination problems, stress accidents, or litter box avoidance.
