Bowel & Bladder Care for DM Dogs
A practical guide to managing incontinence in dogs with degenerative myelopathy, including expressing the bladder, managing accidents, and protecting skin health.
Managing incontinence in a DM dog is one of the hardest parts of this journey â but with the right routine, you can keep your dog clean, comfortable, and infection-free.
If your dog has been diagnosed with degenerative myelopathy (DM), you probably already know the disease is progressive. What the pamphlets don’t always prepare you for is the moment your dog has an accident in their bed and can’t even tell it happened. That hit me harder than almost anything else. But here’s what I’ve learned: this is manageable. It just takes a new routine and a few key skills.
You can read more about how DM unfolds overall in our degenerative myelopathy guides â this article focuses specifically on the bladder and bowel piece, which deserves its own deep dive.
Why DM Causes Bladder and Bowel Problems
Degenerative myelopathy is a progressive neurological disease that slowly destroys the white matter of the spinal cord. As the nerve signals from the brain to the hind end get weaker, your dog loses voluntary control â first over their legs, then eventually over their bladder and bowel sphincters.
This isn’t your dog being lazy or having a behavioral problem. The wiring is literally failing. Most dogs reach the point of incontinence when they can no longer stand or support any weight through their back end. Some dogs show signs sooner; some hold on longer. Either way, it’s coming, and knowing what to do before it arrives makes all the difference.
- Spastic (reflex) bladder: The bladder contracts and leaks involuntarily. Your dog may dribble urine constantly without realizing it.
- Flaccid (atonic) bladder: The bladder loses all tone and overfills because it can’t contract. This type requires manual expression â the bladder will not empty on its own.
Your vet can help you figure out which type your dog has. It matters, because the management approach is slightly different. When in doubt, always check with your vet before starting manual bladder expression at home.
How Do I Express My DM Dog’s Bladder?
Manual bladder expression â gently squeezing the bladder from the outside to empty it â sounds intimidating. I was terrified the first time. But once a vet tech showed me the technique in person, it became as routine as brushing teeth.
Here’s the basic process:
- Position your dog: Most medium and large dogs do best lying on their side. Small dogs can sometimes be held upright over a wee pad.
- Locate the bladder: Feel the lower abdomen, just in front of the pelvis. A full bladder is firm and round. An empty one is soft and hard to find â that’s a good sign.
- Apply steady, gentle pressure: Use both hands cupped around the bladder and apply slow, even inward pressure. Don’t squeeze hard or fast. You’re coaxing, not forcing.
- Release and repeat: Let urine flow into a pee pad or over a drain. Pause, reposition slightly, and express again until you feel the bladder soften.
- Aim for every 4â6 hours: Most dogs need expressing 3â4 times a day at minimum. If your dog leaks between sessions, try more frequent expression.
I can’t stress this enough â have your vet or a vet tech show you in person before attempting this at home. Reading about it is helpful; having someone guide your hands the first time is essential. According to VCA Hospitals, incomplete bladder emptying significantly increases the risk of urinary tract infections, so proper technique really does matter.
- Cloudy, dark, or foul-smelling urine
- Blood in the urine
- Straining or crying during expression
- Fever, lethargy, or loss of appetite
- Urine that was previously clear turning murky
UTIs in paralyzed dogs can escalate fast. If you notice any of these, call your vet the same day â don’t wait.
Managing Bowel Incontinence
Bowel control typically goes a little later than bladder control, but it follows the same nerve pathway. When it goes, it often goes suddenly and completely.
A few things that helped us:
- Feed at consistent times: Predictable feeding times lead to more predictable bowel movements. I feed at the same two times every day.
- Track timing: Most dogs poop 20â40 minutes after eating. If you know your dog’s window, you can position them on an easy-to-clean surface or outside beforehand.
- Stool consistency matters: Soft or loose stool is much harder to manage than well-formed stool. Talk to your vet about fiber or diet adjustments if your dog consistently has loose stools.
- Keep a waterproof mat or “poop station”: I have a designated spot in our living room with a waterproof mat covered in a washable fleece pad. It has saved countless cleanups.
Some caregivers use dog diapers for bowel incontinence, but I find they need to be checked constantly to avoid skin breakdown. They work better as a backup for outings than as a full-time solution.
Protecting Skin: Urine Scald and Pressure Sores
This is the part people don’t talk about enough. Urine sitting against skin â especially in skin folds or under the tail â causes chemical burns called urine scald. It’s painful, it can get infected, and it happens fast.
- Check and clean the perineal area (around the genitals and tail) after every accident
- Use fragrance-free, hypoallergenic dog wipes for quick cleanups
- Apply a barrier cream (like plain petroleum jelly or a vet-approved product) to vulnerable skin
- Keep the fur around the hindquarters trimmed short â a groomer can help you with this
- Inspect for redness, raw skin, or sores at every diaper or bedding change
Bedding matters enormously here too. Waterproof mattress covers under a washable fleece pad are a game-changer. The fleece wicks moisture away from your dog’s skin while you deal with the mess underneath. I wash our fleece pads every single day â it’s just part of the routine now.
For dogs who are fully down (unable to walk at all), also check for pressure sores over bony points like hips, elbows, and the base of the tail. Turning your dog every few hours and using a supportive orthopedic bed helps prevent these. Our neurological care guides cover positioning and pressure sore prevention in more depth.
- Urine has blood in it or smells strongly of ammonia
- Your dog cries or seems distressed during bladder expression
- You feel resistance or the bladder won’t empty despite correct technique
- Skin sores that appear red, swollen, warm, or discharge fluid
- Your dog hasn’t urinated in more than 8 hours
Does It Get Easier?
Honestly? Yes. The first two weeks of managing incontinence felt completely overwhelming â I cried more than I’d like to admit. But like everything with caring for a disabled dog, you build a system, your hands learn the routine, and it stops feeling like a crisis every time.
Your dog is still in there â still wagging, still watching you with those eyes. They don’t feel ashamed or broken. The incontinence is just a logistics problem, and you are more capable of solving it than you think. Lean on your vet, connect with other DM caregivers online, and give yourself credit for showing up every single day.
Frequently Asked Questions
When do DM dogs lose bladder and bowel control?
Most dogs with degenerative myelopathy lose bladder and bowel control in the mid-to-late stages, typically when they can no longer support their hindquarters at all. It varies dog to dog, but if your dog is dragging both back legs consistently, incontinence is likely coming soon.
How do I know if my DM dog’s bladder is full?
Gently palpate (feel) your dog’s lower belly, just in front of the pelvis. A full bladder feels like a firm, round water balloon. If your dog seems restless, is leaking urine, or hasn’t urinated in over 6 hours, check for bladder fullness right away.
Can a DM dog get a urinary tract infection from incontinence?
Yes â UTIs are one of the most common complications in dogs with DM-related incontinence. Urine pooling around the skin, incomplete bladder emptying, and catheter use all raise the risk. Watch for cloudy or foul-smelling urine, straining, or blood in the urine and call your vet promptly.
Should I use diapers or belly bands for my DM dog?
They can help manage messes, but they must be changed frequently â every 2 to 4 hours â to prevent urine scald and skin infections. Never use diapers as a substitute for regular manual bladder expression if your dog has lost voluntary bladder control.
