Your dog just had IVDD surgery, and now you’re crouched over the incision at 11pm on a Tuesday, second-guessing everything you think you see.

I have been exactly there. The good news is that most of what you’re looking at is normal — but there are specific signs that genuinely do need a vet call, and knowing the difference will save you a lot of panic (and protect your dog). This guide walks you through what to expect at each stage of healing, what’s reassuring, and what’s a hard “call now.”

Quick answer: A healing IVDD incision should be closed, with mild pinkness and minimal clear or pale discharge in the first few days. By day 7, redness should be fading and the wound should look knitting together. Infection warning signs — yellow or green discharge, a foul odor, significant swelling, or a wound that opens — mean a vet call the same day. A complete wound opening, bright-red bleeding, or sudden worsening of your dog's hind-leg function is an emergency. When in doubt, photograph the incision and text it to your vet clinic before driving in.

What Does a Healthy Incision Look Like at Each Stage?

A healthy IVDD incision changes noticeably over two weeks, and knowing what to expect at each checkpoint is the best way to catch a real problem early.

Day 1–2: Fresh from Surgery

The incision will look red and raw — that is completely expected. The area directly around the sutures or staples may be shaved and slightly irritated from surgical prep. You might see a tiny amount of clear or very pale pink fluid seeping from the wound edges. The incision itself should be closed; no gaps.

What should already be absent: bright-red active bleeding, any yellow or green discharge, and any gaping.

Day 3–5: Early Healing

Mild pinkness and some puffiness along the suture line are still normal at this stage. The edges will start to look like they’re knitting together. A small amount of dried crusting (serosanguineous crust — a mix of dried serum and a trace of blood) around the staples or sutures is normal and expected. Do not pick it off.

This is also when seromas can appear. More on those below.

Day 7: The Halfway Point

By day 7, the redness should be visibly fading compared to day 3. The incision line should look drier, flatter, and more defined. Most dogs are having their first post-op recheck around this time. If your vet scheduled that visit, it’s a good moment to have a set of professional eyes confirm everything looks right.

Day 10–14: Suture or Staple Removal

Most IVDD surgeries use sutures or staples that are removed around the 10–14 day mark at a scheduled follow-up. By this point, the incision should look almost fully healed on the surface: pale pink to skin-colored, flat, and dry. Some surgeons use internal dissolvable sutures with skin glue on the surface, which skip the removal visit entirely.

After removal, the line may look slightly raised or have a thin scar ridge — that’s normal scar tissue forming.

Normal Incision Checklist by Stage
  • Day 1–2: Closed wound, mild redness, trace of clear/pale-pink fluid
  • Day 3–5: Slight puffiness, dried crusting around sutures, still closed
  • Day 7: Redness fading, wound knitting together, drier appearance
  • Day 10–14: Pale and flat, ready for suture/staple removal

What Discharge Is Normal — and What Isn’t?

This is the question I get asked the most, and it genuinely matters.

Normal discharge:

  • Clear or pale straw-colored fluid: This is serum, a natural part of wound healing. A small amount in the first few days is fine.
  • Pale pink-tinged fluid: A tiny trace of blood mixed into serum, usually in the first 24–48 hours.
  • Dried rust-colored crust: Old serum that has dried around the staples. Looks alarming, is normal.

Call your vet the same day if you see:

  • Yellow or green discharge: This color signals bacterial activity. It is not normal at any stage.
  • Thick, opaque fluid: Pus. This needs to be evaluated.
  • Any discharge with a foul or unusual smell: Infected wounds have a distinct odor. Trust your nose.
  • New discharge after things had seemed dry: A wound that starts weeping again after day 5 or 6 warrants a call.

A quick photo sent to your vet clinic is often enough to get a same-day answer without a trip in — more on that below.

What About Swelling and Seromas?

Seromas are a common post-IVDD surgery finding that can send owners into a panic — understandably, because a squishy lump under an incision looks alarming.

A seroma is a pocket of clear to pale-yellow fluid that collects under the skin, typically appearing between days 3 and 10. It feels soft and moveable, like a water balloon just under the surface. Seromas form because the body’s lymphatic drainage gets disrupted during surgery, and fluid takes the path of least resistance.

The important things to know:

  • Most seromas resolve on their own without any treatment over a few weeks.
  • Do not drain it at home. Introducing bacteria through even a tiny puncture can cause the infection you’re trying to avoid.
  • Get it confirmed by your vet. What feels like a seroma could occasionally be something that needs attention. A quick visit or even a photo with a description usually clarifies it.
  • A seroma that grows rapidly, becomes firm, or gets warm to the touch should be evaluated sooner rather than later.
Signs That Need a Same-Day Vet Call
  • Yellow, green, or thick discharge from the incision
  • Foul smell from the wound at any stage
  • Wound edges separating or partially opening
  • Swelling that grows quickly or feels warm and firm
  • New redness spreading outward from the incision line after day 5

How Do You Prevent Your Dog From Licking the Incision?

Licking is the single most common reason IVDD incisions get infected or re-open. Dogs are persistent, creative, and will absolutely reach a back incision if you give them five unsupervised minutes.

The standard tool is an e-collar — the cone that most dogs find deeply undignified. We kept a dog cone on Heidi throughout her recovery, taking it off only for supervised meals and bathroom trips. It felt cruel at first. An infected incision felt worse.

A few practical notes:

  • Inflatable collars are more comfortable but don’t always block access to a back or lumbar incision. Test yours.
  • Recovery suits (soft onesies that cover the torso) can work as a backup but should not fully replace the collar in the early healing phase.
  • Never rely on “she won’t bother it.” She will. They all do, eventually.

For paralyzed or partially paralyzed dogs especially, this matters even more. Dogs with impaired sensation may nibble at their incision without any behavioral signal that they’re doing it — they literally can’t feel what they’re doing to themselves.

When to Photo-Text vs. Drive In

Not every concern needs a midnight emergency visit. Here’s a practical framework:

Photo-text to your vet clinic (next business hours is fine):

  • Small amount of clear or pale discharge
  • Mild crusting around sutures
  • A soft, non-growing lump that appeared around days 3–7 (likely seroma)
  • General “does this look right?” uncertainty

Call the clinic first thing in the morning (same-day appointment):

  • Yellow or green discharge
  • Wound that smells off
  • Edges that look like they’re separating but the wound is not fully open
  • Seroma that has grown noticeably overnight

Emergency vet, now:

  • Wound has opened — you can see tissue underneath
  • Bright-red bleeding that doesn’t stop with gentle pressure
  • Sudden loss of bladder or bowel control that wasn’t present before
  • Sudden worsening of hind-leg function

That last two items are not incision problems — they’re signs of possible spinal cord changes that need immediate evaluation. The IVDD emergency signs page covers those triggers in more detail.

Go to the Emergency Vet Now
  • The incision has opened and you can see deeper tissue
  • Bright-red active bleeding that doesn’t slow with gentle pressure
  • Sudden new paralysis, loss of bladder control, or inability to feel the hind paws
  • Your dog is in severe pain and cannot be calmed
Things You Can Do Right Now
  • Take a clear photo of the incision in good lighting — keep a dated folder for comparison
  • Make sure the e-collar is properly fitted and being worn
  • Check that your dog cannot reach the incision even when lying in odd positions
  • Confirm your follow-up recheck appointment is scheduled for day 10–14

The day-by-day picture of what to watch for beyond the incision is covered in detail in the IVDD recovery days 1–7 guide and the post-op IVDD care: first 30 days article — both of which walk through the broader recovery picture alongside incision healing.

The first week after IVDD surgery is a lot. You’re managing medications, crate rest, bladder care, and now incision monitoring on top of running on very little sleep. Most incisions do heal cleanly — the odds are in your favor. But when something looks genuinely wrong, the two-minute decision to call your vet is always the right one.

Frequently Asked Questions

What does a normal IVDD incision look like on day 3?

On day 3, mild pinkness along the incision edges and a small amount of clear or pale-pink seeping is normal. There may be slight puffiness around the suture line. What’s not normal is yellow or green discharge, a foul smell, or a wound that has opened.

When should I call the vet about my dog’s incision?

Call your vet the same day if you see yellow or green discharge, a bad smell, a wound that has partially opened, or a growing lump that feels warm. Go to an emergency vet immediately if the incision opens fully, you see bright-red bleeding that doesn’t stop, or your dog’s back legs suddenly worsen.

What is a seroma and is it dangerous?

A seroma is a pocket of clear or pale-yellow fluid that can form under the skin near the incision, usually appearing around days 3–10. It looks like a soft, squishy lump. Seromas are generally not dangerous, but always have your vet confirm the diagnosis — they should not be drained at home.

When are IVDD surgery stitches or staples removed?

Most IVDD surgery incisions are closed with sutures or staples that are removed at a scheduled follow-up appointment, typically around 10–14 days post-surgery. Some surgeons use dissolvable sutures internally with skin glue on the surface, which require no removal visit.

This guide is based on real experience and should be used alongside professional veterinary care. Always consult your veterinarian before starting any new treatment or making changes to your dog’s care plan.
