Getting Your IVDD Dog to the Bathroom Post-Op

Getting your IVDD dog outside to use the bathroom after surgery is one of the most physically and emotionally demanding parts of early recovery — and nobody prepares you for how hard it actually is.

Heidi came home from her IVDD surgery unable to use her back legs at all. I had vague instructions on paper, a sling I’d never used, and a dog who had no idea what was happening. The first bathroom trip was a disaster. By week two, we had a system. This guide is what I wish I’d had on day one.

Quick Steps: The Post-Op Bathroom Routine

1. Gather your sling, pee pads, and gloves before you touch your dog.
2. Lift your dog using the sling under the belly, keeping the spine level.
3. Carry or walk your dog to the same outdoor spot every time.
4. Hold the sling steady and give your dog 3–5 minutes to attempt urination.
5. Watch for squatting, straining, or a stream — signs the bladder is working.
6. If no urination occurs after 5 minutes, move to manual bladder expression.
7. After the bathroom trip, check skin for urine contact and wipe clean if needed.
8. Log the time, whether urination happened, and approximately how much.
9. Return your dog to the crate for rest.
10. Repeat every 4–6 hours during the day; set an overnight alarm for the midpoint.

How Do I Do a Sling Walk Correctly?

A sling walk for a post-op IVDD dog is a supported outdoor trip where you hold the rear end up while the dog either moves its front legs or is fully carried, depending on their grade. The sling goes under the belly behind the rib cage — not around the waist — and you hold both handles level to keep the spine neutral and the hips from dragging.

Choosing Your Sling

For early post-op recovery, you need something with padded handles that can support your dog’s full rear weight without cutting into your hands. A rolled-up bath towel works in a pinch, but it’s hard to hold for more than a minute. A purpose-made rear harness gives you much better control and protects the surgery site. The Help ‘Em Up Harness was what we used with Heidi — the padded handle made a real difference when we were doing five or six trips a day.

Positioning for the Walk

Spine alignment: Keep your dog’s back as level as possible. Avoid letting the hips sag or tip sideways.

Height: The hindquarters should be just high enough that the paws brush the ground lightly — or clear it completely if your dog is knuckling badly and scraping.

Your posture: Bend your knees, not your back. You will be doing this many times a day. Protect yourself.

Duration outside: Keep it short — 5 to 10 minutes maximum in the first two weeks. You are out there for one purpose only.

What If My Dog Can’t Urinate on Their Own?

Bladder dysfunction is extremely common after IVDD surgery, especially in Grade 3, 4, and 5 cases. The spinal cord injury that caused the hind-leg weakness can also disrupt the nerve signals that control the bladder. This means your dog physically cannot feel the urge to go, or cannot coordinate the muscles to release urine — even when the bladder is full.

A dangerously overfull bladder is a medical emergency. If your dog hasn’t urinated in 8 hours, call your vet immediately.

How to Tell If the Bladder Is Full

Gently place your hand on your dog’s lower abdomen — just in front of the pelvis, slightly to one side of the midline. A full bladder feels like a smooth, firm oval, like a water balloon that hasn’t been filled all the way. An empty or near-empty bladder is soft and hard to feel.

Manual Bladder Expression

For a full step-by-step technique guide, see Bladder Expression for IVDD Dogs: Step-by-Step. The summary: position your dog either standing (supported by the sling) or lying on their side, locate the bladder, and apply steady, even pressure with both hands. You are not squeezing hard — you are applying consistent, moderate pressure until the urine flows. Stop immediately if you feel resistance, or if your dog cries.

Expression should happen every 6–8 hours. Many owners find it easiest to do it at the end of each sling walk — try the natural urination first, then express whatever remains.

UTIs are a genuine and common risk for dogs who need manual expression. For more on prevention and what to watch for, UTIs in Paralyzed Dogs: Prevention & Care covers this in depth.

How Often Should Bathroom Trips Happen?

During waking hours, every 4–6 hours is the standard recommendation for most post-op IVDD dogs. That works out to roughly four trips during the day. In the first few days home, I erred on the shorter side — every 4 hours — because Heidi was on steroids, which increases water intake and urine output.

A rough schedule that worked for us:

Yes, the 3 AM alarm is brutal. But a dog left with an overfull bladder for 8+ hours overnight risks serious complications, and bladder overdistension can actually slow the return of normal bladder function. Set the alarm.

How Do I Encourage My Dog to Urinate?

Some dogs, even those with some bladder function remaining, become reluctant or confused about the urination process after surgery. A few things that helped with Heidi:

Same spot, same cue: Use a consistent verbal cue — “go potty,” “hurry up,” whatever you normally use. Pair it with the same patch of ground every time.

Running water trick: For dogs who are struggling to start, running a trickle of cool water over the vulva or prepuce can sometimes stimulate urination. I used a small squeeze bottle.

Warm cloth on the lower belly: Gentle warmth applied to the lower abdomen for 30–60 seconds before attempting expression can help relax the bladder muscles.

Patience: Give them the full 3–5 minutes. Stand quietly. Don’t hover anxiously or rush. Dogs pick up on our stress.

What About Bowel Movements?

Most IVDD post-op dogs go 24–48 hours after surgery before their first bowel movement, partly from anesthesia and partly from reduced food intake. When it does happen, it usually happens during a sling walk — and it may surprise both of you.

The mechanics are the same as the bathroom trip: hold the sling steady, let the dog squat as naturally as possible. Some dogs need gentle abdominal support to position correctly. If your dog hasn’t had a bowel movement by 48–72 hours post-discharge, mention it to your vet — they may recommend a stool softener.

The Overnight Strategy

The overnight stretch is the hardest part of the first week. Here is what worked for us:

Set your alarm for the middle of the night — typically 4–5 hours after the pre-bed trip. Keep a headlamp, your sling, and disposable wipes right next to the crate so you’re not fumbling in the dark. Move quietly and calmly. The goal is in and out in under 10 minutes so your dog can go back to sleep.

If your dog is in diapers overnight (which is completely reasonable for early recovery), you still need to check and change them during the night trip to prevent urine scald. A quick wipe-down and fresh diaper takes two minutes.

The bathroom routine gets easier. By week two, Heidi and I had it down to muscle memory — sling on, same spot, a few minutes, done. The first few days feel impossible, but you will find your rhythm. You’re not doing this wrong; you’re just doing it for the first time.

Frequently Asked Questions

How often should I take my IVDD dog out to the bathroom after surgery?

Most post-op IVDD dogs need bathroom trips every 4–6 hours during the day. If your dog cannot urinate on their own, your vet will show you how to express the bladder, typically every 6–8 hours — though the exact schedule depends on your dog’s neurological status and your vet’s instructions.

How do I know if my IVDD dog’s bladder needs expressing?

Gently palpate (feel) your dog’s lower abdomen — a full bladder feels like a firm, round balloon. If your dog hasn’t urinated in 6–8 hours or seems restless and uncomfortable, it’s time to express. When in doubt, call your vet.

What if my dog won’t urinate on the sling walk?

Give them a few minutes in the same spot — scent from previous visits helps trigger the urge. Try gently running cool water over the vulva or prepuce, or using a warm, wet cloth on the lower belly. If your dog goes more than 8 hours without urinating, call your vet right away.

When can I stop manually expressing my IVDD dog’s bladder?

Once your dog is consistently voiding on their own during sling walks — meaning the bladder empties fully without your help — you can stop manual expression. Your vet will confirm at your follow-up recheck. Most dogs who regain bladder function do so within the first 2–4 weeks post-surgery, though this varies by grade.
