Lump After Spay or Neuter Incision: What to Do?

Lump After Spay or Neuter Incision

Usually, after a dog gets spayed or neutered, they come back for a checkup about three days later and then again after 14 days. We do this to make sure everything is okay with their surgery, like looking for any issues with the incisions, such as lumps or discharge.

Most pets that get neutered don’t have any problems, but if there are issues, it’s not unusual for lumps to form. These lumps can be caused by different things, and it’s important for us to investigate them further. Let’s dive into the lumps we come across and the recommended treatments.


Is it normal for a dog to have a lump after a spay or neuter surgery?

Certainly! It’s not uncommon for dogs to develop a lump after undergoing spay or neuter surgery. In many cases, these lumps are part of the normal healing process and don’t pose any significant issues. However, it’s important to keep an eye on the lump, and if you notice anything unusual or if it seems to be causing discomfort to your dog, it’s advisable to consult with your veterinarian.

They can thoroughly examine the lump, assess whether it’s a typical part of the healing process, or if further investigation or treatment is necessary. Regular post-surgery check-ups are designed to catch any potential complications early on, ensuring the well-being of your pet.


What are the common causes of lumps after neutering?

The lumps after a neutering incision can happen for a few common reasons. Sometimes it’s just part of the normal healing process. Other times, it could be a reaction to stitches or the body’s response to the surgery. Most common reasons are:


Normal Healing Process:

After a neutering surgery, the body initiates a healing response, and part of this process can involve the formation of a lump near the incision site. It’s akin to the body’s way of repairing and rebuilding tissues. This type of lump is generally a temporary and expected aspect of the healing journey.


Reaction to Stitches:

Stitches are often used to close the incision after surgery. In some cases, the body may react to these stitches, leading to the formation of a lump. This response is essentially the body acknowledging and responding to a foreign material. While it may cause a temporary lump, it usually resolves as the stitches do their job.


Body’s Response to Surgery:

The overall trauma caused by the surgery, even when it’s routine, can prompt the body to respond with swelling and the development of lumps. This is a common reaction as the body adapts to the changes brought about by the surgical procedure. Over time, as healing progresses, these lumps typically subside.



In some cases, a lump may be indicative of an infection in the incision area. Infections can cause localized swelling, redness, and sometimes discharge. It’s crucial to address infections promptly, as they can impede the healing process and potentially lead to more serious complications.


Fluid Buildup (Seroma or Hematoma):

Another possible cause of post-surgery lumps is the accumulation of fluid. This can manifest as a seroma, which is a clear fluid buildup, or a hematoma, involving blood accumulation. These fluid-related lumps can occur as part of the normal healing process or as a response to a minor complication. Monitoring these lumps and seeking veterinary advice ensures appropriate management and intervention if needed.


When to worry about a lump?

If you’ve noticed a lump near your dog’s incision site post-surgery, it’s crucial to be vigilant for potential issues. Keep an eye out for any increased redness around the lump, which might indicate irritation. Swelling in the area is another visible sign to be mindful of.

Watch for signs of discomfort, such as frequent licking, biting at the lump, or any indications of pain like whimpering or aversion to touch. Additionally, observe for changes in overall behavior, including increased lethargy or a reduction in regular activity levels. Should the lump persist without improvement or if it grows larger, it’s a clear indication to consult your veterinarian. Here’s a summarized list of signs to watch for:

  1. Increased Redness
  2. Swelling
  3. Discomfort or Pain
  4. Changes in Behavior
  5. Lump Persistence or Growth


When to call the vet?

Call the vet if you notice any red flags like increased redness, swelling, or if your dog seems uncomfortable or in pain. Changes in behavior, such as lethargy or a decline in activity, are also reasons to reach out. If the lump doesn’t go away or if it’s getting bigger, it’s time to pick up the phone and consult with your vet. They can give you guidance on what to do next and ensure your dog gets the care they need. It’s always better to be safe and get professional advice when you’re unsure.
