A lump at the spay incision site can be alarming, but understanding what it is and what it might mean can help you feel more in control.
In most cases, a lump at the spay incision site is a normal part of the healing process.
The lump is often a result of the body's natural response to the surgery, with the skin and tissues reacting to the incision.
It's usually a sign that the body is working to close the wound and promote healing.
In some cases, the lump can be a sign of a more serious issue, such as an infection or an allergic reaction to the sutures.
It's essential to keep an eye on the lump and monitor its size, shape, and color to catch any potential problems early.
If you notice any redness, swelling, or discharge around the lump, it's a good idea to contact your veterinarian for advice.
What Is a Seroma?
A seroma is a collection of serous fluid beneath the skin, which is the clear, watery part of blood that helps transport nutrients and waste products.
Serous fluid can leak from blood vessels and collect beneath the skin, forming a seroma. This can be evident as a soft, sometimes squishy lump beneath a surgical incision or wound.
A seroma in dogs is typically clear to yellow-tinged and is sticky when touched. It's usually not painful, and they can vary greatly in size.

Symptoms and Diagnosis
Symptoms of a dog spay incision lump can be concerning for pet owners.
A biopsy is the only definitive way to diagnose mammary cancer in canines, which is a possible cause of a lump at a spay incision site.
Your veterinarian may recommend having blood work to check on your dog's general health before any surgery to remove the lump.
Other tests can be performed to see if the cancer has spread, such as an x-ray or ultrasound.

Mammary Gland Tumor Symptoms
Mammary gland tumors in dogs can be a serious issue, and it's essential to be aware of the symptoms. A solid mass or multiple swellings in the mammary glands are the most common signs of a tumor.
These tumors are relatively easy to detect by feeling the mammary glands, and an early tumor may feel like small pieces of pea gravel. If you number your dog's teats from 1-5, with 1 being closest to the head and 5 being closest to the tail, mammary tumors often occur near teats 4 and 5.
The masses can be red, purple, or fleshy in color and may be soft or hard. If you notice bleeding or ulceration near the teats, it's a sign of advanced cancer and you should seek veterinary attention immediately.
Some other signs of advanced cancer include loss of weight, appetite, and lethargy. These symptoms can be a sign that the tumor has progressed and requires urgent attention.
Here are the types of benign tumors, as classified by Rave Foster DVM:
- Complex adenomas
- Fibroadenomas
- Duct papillomas
- Simple adenomas
Malignant tumors, on the other hand, tend to have an irregular shape, are firm and attach to the skin, and grow rapidly.
Mammary Gland Tumor Diagnosis
Diagnosing mammary gland tumors in dogs requires a biopsy, which is the only definitive way to determine if the growth is benign or malignant. This involves taking a sample from the tumor and sending it to a lab for analysis.
Other tests can be performed to check if the cancer has spread, such as an x-ray or ultrasound. These tests can help identify if the cancer has metastasized to other parts of the body.
Most veterinarians also recommend having blood work done to check the dog's overall health before any surgery.
Treatment and Prevention
Draining a seroma with a needle and syringe is not recommended, as it increases the risk of infection.
Restricting activity and applying warm compresses to the affected area can help the seroma resolve on its own over a couple of weeks. This involves applying warm compresses for a few minutes a few times a day.
If your dog's seroma is leaking fluid, painful to the touch, or causing discomfort, it's essential to have your veterinarian assess it and possibly prescribe antibiotics to prevent or treat infection.
To prevent a seroma from forming in the first place, make sure your dog rests and stays calm after surgery, avoiding strenuous activities like running or jumping until the incision has fully healed.
Preventing Dog Seroma
To prevent a seroma from forming in your dog, it's essential to keep them calm and rested after surgery. This will help minimize the disruption to the body's natural repair process.
Avoid letting your dog run, jump, or play until the surgical incision has healed. This will reduce the risk of disturbing the healing process and causing serous fluid to leak out.
Keep a close eye on the surgical incision and look for any signs of serous fluid leaking. If you notice a fluid discharge, call your vet right away.
By following these simple steps, you can significantly reduce the likelihood of a seroma occurring in your dog.

Mammary Gland Tumor Treatment
Mammary gland tumors are a serious issue for dogs, but there are treatment options available. Surgery is the best and most used treatment for cancer, where veterinarians remove the tumor along with a large area of surrounding tissue.
In some cases, surgery may not be enough, and chemotherapy may be recommended. However, it's worth noting that chemotherapy has no proven efficacy for canine mammary tumors according to the Ohio State University Veterinarian Medical Center.
If your dog has a high-grade, aggressive, and invasive tumor, chemotherapy may be an option. But it's essential to discuss this with your veterinarian to determine the best course of action.
Radiation therapy is uncommon for mammary gland tumors, but it may be recommended for certain types of cancers.

Post-Surgery and Complications
After your dog's spay procedure, it's normal for them to feel a little queasy or tired due to anesthesia.
You'll need to keep an eye on their appetite, as it will be reduced during the first 24 hours.
Your dog will also need to wear a cone to avoid licking the incision site, and you should not bathe or allow them to swim for at least 10-14 days.
It's essential to keep the wound dry until it heals, so make sure to keep an eye on the incision site and keep your dog away from any excitement.
Dogs don't understand the importance of rest, so you'll need to limit their movements and keep them in their crate or a small room.
Restricting their activities and ensuring they get enough rest will help them recover faster.
Even if your dog tries to run or jump, this won't speed up the healing process, so be patient and keep them calm.
Broaden your view: Dog Lump above Eye
The recovery time for a spayed female dog is approximately 10-14 days, which is about the same as for neutering male dogs.
If you notice serious fluid leaking from the surgical incision, call your vet right away, as this could be a sign of a seroma or infection.
A seroma is usually nothing to worry about and will resolve on its own with time, but it's always best to err on the side of caution and consult your vet.
Seromas are more common after spay surgery, especially in puppies who are very active and hard to keep quiet.
If you have a very excitable pup, you may want to ask your veterinarian for some sedation to keep her quiet for 7-10 days after the procedure.
