What treatment works depends on why your dog is incontinent

Dog incontinence is treatable, but the right approach depends on the cause. A urinary tract infection, hormonal imbalance, or anatomical problem each respond to different treatments. Your veterinarian will need to identify the underlying reason before starting treatment — this usually involves a physical exam, urinalysis, and sometimes imaging like ultrasound or X-rays.

Some causes resolve quickly with medication. Others require long-term management or, occasionally, surgery. A few are manageable but not curable, meaning you and your dog will live with the condition using tools and routines that keep it under control.

Key Takeaways

  • Incontinence has multiple causes — infection, hormonal changes, weak sphincter muscles, or structural problems — and each responds to different treatments.
  • Your vet will run tests to find the cause before recommending treatment, which may include antibiotics, hormone replacement, or surgery.
  • Medications like phenylpropanolamine can strengthen the muscles that hold urine, while others address the root problem.
  • If medication does not work or the cause is structural, your vet may recommend surgery or a combination of management strategies.
  • Incontinence that develops suddenly or is accompanied by other symptoms like excessive thirst or weight loss needs prompt veterinary attention.

Antibiotics and urinary tract infections

If your dog has a urinary tract infection (UTI), antibiotics are usually the first treatment. UTIs are common in incontinent dogs and sometimes are the only problem — once the infection clears, continence returns. Your vet will prescribe an antibiotic based on a urine culture, which identifies the bacteria and which drugs work against it.

Treatment typically lasts 7 to 14 days. Your vet may recheck the urine after treatment ends to confirm the infection is gone. If incontinence persists after the infection clears, your vet will investigate other causes.

Hormone replacement for spay incontinence

Spay incontinence — leaking that begins months or years after spaying — happens because the surgery removes the ovaries, which produce estrogen. Estrogen helps maintain the muscle tone of the urinary sphincter. Without it, some dogs lose the ability to hold urine, especially when resting or sleeping.

Diethylstilbestrol (DES) is a synthetic estrogen that replaces what the ovaries no longer produce. It is given as a tablet, usually once daily at first, then tapered to the lowest dose that controls leaking. Many dogs respond well, though it can take a few weeks to see improvement. If DES does not work or causes side effects, your vet may try phenylpropanolamine instead, which works through a different mechanism.

Phenylpropanolamine and sphincter strengthening

Phenylpropanolamine (PPA) strengthens the muscles that close the urethra, the tube that carries urine. It works for incontinence caused by a weak or incompetent sphincter — the most common cause in older dogs and in dogs of certain breeds like Doberman Pinschers and Old English Sheepdogs.

PPA is given as a tablet two or three times daily. Some dogs respond within days; others take weeks. If your dog shows no improvement after four weeks, your vet will likely try a different medication or combination. PPA can raise blood pressure, so your vet may monitor this, especially in dogs with heart disease or hypertension.

Combination therapy and other medications

If one medication does not fully control incontinence, your vet may combine treatments. For example, a dog might take both PPA and DES, or PPA plus an antibiotic if a low-grade infection is also present. Some vets add doxycycline, an antibiotic with anti-inflammatory properties, to reduce inflammation in the bladder.

Other medications your vet might consider include imiprimine, a tricyclic antidepressant that relaxes the bladder and tightens the sphincter, or bethanechol, which increases bladder contractions. The choice depends on your dog's age, other health conditions, and how the incontinence presents.

Surgery for structural problems

Some dogs are born with anatomical abnormalities — an ectopic ureter (a ureter that empties in the wrong place) or a patent urachus (a fetal vessel that did not close properly). These cause constant or near-constant leaking and usually cannot be managed with medication alone. Surgery to correct the anatomy is often the only effective treatment.

Surgery is also an option for severe sphincter weakness that does not respond to medication. Procedures like urethral bulking (injecting material to narrow the urethra) or sling procedures (supporting the urethra with tissue) can help, though they are not available at all veterinary clinics. Your vet can refer you to a surgical specialist if your dog is a candidate.

Managing incontinence when treatment is limited

Some dogs have incontinence that cannot be fully cured — either because the cause is not treatable or because medication and surgery have not worked. In these cases, management focuses on keeping your dog comfortable and your home clean.

Strategies include more frequent outdoor breaks (some dogs need to go out every 2 to 4 hours), washable pee pads or belly bands for male dogs, and waterproof bedding. Some owners use doggy diapers or incontinence pants. Keeping the area around the genitals clean and dry prevents skin infections. Your vet can recommend products designed for incontinent dogs and may suggest dietary changes — increasing water intake or adjusting meal timing — to make leaking more predictable.

When to contact your veterinarian

Incontinence that develops suddenly, especially in a young dog, needs prompt evaluation. Also seek care if incontinence is accompanied by other signs: excessive thirst, weight loss, lethargy, straining to urinate, blood in the urine, or fever. These can indicate infection, diabetes, kidney disease, or other serious conditions.

If your dog is already being treated for incontinence but the leaking is getting worse, or if medication side effects develop, contact your vet. Treatment plans sometimes need adjustment as your dog ages or as the underlying condition changes.

Frequently Asked Questions

How long does it take for incontinence medication to work?

Some dogs improve within days, while others take two to four weeks. If your dog shows no improvement after four weeks on a medication, tell your vet — they may adjust the dose, switch medications, or add a second drug. Do not stop medication without talking to your vet first.

Can incontinence in dogs be cured?

It depends on the cause. UTIs are curable with antibiotics. Spay incontinence is manageable with hormone replacement or other medications. Structural problems may be curable with surgery. Some cases of age-related sphincter weakness can be controlled but not fully cured, requiring lifelong medication or management.

Is incontinence painful for dogs?

Incontinence itself is not painful, but the underlying cause sometimes is. A UTI can cause discomfort or pain during urination. Skin irritation from constant wetness can become uncomfortable. Treating the cause and keeping your dog clean and dry reduces discomfort.

What if my dog is incontinent at night but not during the day?

Nighttime-only incontinence is common in older dogs and often responds well to medication like PPA or DES. It can also improve with a late-evening bathroom break or by limiting water intake a few hours before bed. Your vet can determine whether medication is needed or whether management changes are enough.

Can diet affect incontinence?

Diet does not cause incontinence, but it can affect how often your dog needs to urinate. Some vets recommend feeding at set times rather than free-feeding, so bathroom breaks become more predictable. Increasing fiber may help some dogs. Ask your vet whether dietary changes might help your dog's specific situation.
