My dog has a hard lump on her spay scar. Could it be stitches?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Female | spayed | 6 months and 15 days old | 28.4 lbs

I have a dog which I got from a rescue centre. They spade her and from what my vet has said the stitches they put in weren’t dissolvable ones now recent I have found a hard lump down her scar which is worrying me. Could this be due to the stitches.

Congrats on your new dog! This could be due to a local tissue reaction from the internal sutures, which should be dissolvable. It's normal to use non-dissolvable sutures on the external incision as they can be removed, while the internal incisions do require dissolvable ones since those could only be removed by opening up the external incision. You can still get a local tissue reaction from the internal sutures, but it's always best to have Nina checked out to be sure. It could also be scar tissue depending on how long ago she was spayed. Take her into the vet tomorrow to have her incision examined. Good luck, I hope this helps!

I noticed a small lump along her incision line from her spay surgery. Any idea what this could be?
Thank you for providing a picture of Mabel's incision! This small lump could be a local tissue reaction from an internal suture, scar tissue, a seroma (fluid in the dead space from a surgery), or a cyst. I'm not sure if the lump is hard or soft. The incision itself looks like it healed beautifully, but i would have this lump checked out by the vet to be safe. The vet can diagnose what is causing it and if it needs any treatment. Good luck, I hope this helps!

My dog got spayed (early caught Pyometra) in November 2018 and I noticed that the incision healed but one of the ends looks like the attached picture and it doesn’t seem normal, what could this mean? Thank you!
Hi, it does look like a reaction to subcutaneous sutures. It could just be inflammation or an infection. I would recommend to have it checked over at your vets, to see wether does need an antibiotic /antinflammatory ointment or injection or better some oral medications. The decision will depend on how the lump feels and on its content ! Hope this helps.

My 8 month Boston Terrier got spayed 3 weeks ago her incision was healing perfectly till I noticed a lump on top of her incision. It is very firm but doesn’t seem to hurt her
This could just be a local tissue reaction to an internal suture. Lola's incision looks great, so I'd just keep an eye on the lump for now. If it gets bigger, doesn't go away, or starts bothering her, have her see a vet. Best of luck.

I got my dog spayed almost 2 months ago. This lumb came up 3 days ago. Its hard and you can move it around. I attached some photos. Thank you!
From the picture, that looks like a suture reaction, which is common a month or two out from surgery as the internal suture material is dissolving. If there is no discharge and it's not warm to the touch, and she's otherwise normal, it shouldn't need medical attention. However if it starts to bleed or have discharge, take her in for a check up

I adopted my dog from the shelter where she was spayed. When I got her I noticed around her tattoo is a long lump. Its still there but she's grown so it's less noticeable. It doesn't seem to affect her in any way but I'm still worried as to what it i
I recommend contacting the shelter vet to have this assessed - it may be simply a sensitivity reaction to the stitches/tattoo ink or could possibly be related to poor healing, a mild hernia or abscess in the wound.It is a good sign that she is otherwise well and although not an emergency situation the earlier this is assessed and corrected if necessary the better chance of a full resolution

Our yorkie was spayed Oct 7, so almost 3 weeks ago. Both of these lumps at the top and bottom of her incision have just come up. It doesn't hurt her for me to mess with them and they feel maybe a little hard. She is a rescue and the vet is 2 hours aw
Hi there and thank you for using Boop by Petco to address your concern. The picture is a bit grainy and discolored so it is difficult to say for sure what the problem is. However, with your description, what you are feeling are likely the knots of the suture at the top and bottom portion of the incision line. These knots can sometimes cause inflammation due to a slight suture reaction. If the incision is not open, then I would just monitor for now. If the incision is red, inflamed or there is pus present, then I would have Huggle rechecked by the veterinarian that did the procedure. I hope this helps guide you in the right direction! If the bumps are indeed due to the suture and they do not worsen, you should see those disappear over the next few months hopefully. Complete absorption of the suture I use in my spay procedures takes about 3-4 months to occur. However, absorption time depends on the type of suture used.

I have an 8 month old lab mix who I just adopted 2 months ago. She was spayed at time of adoption and is due for her Lepto booster in a week. At the base of her scar there has grown rather quickly a 1x1cm round, reddened, shiny, raised, hard but mobi
Hi there! It sounds like you're a very good friend to Athena and care very much. This looks very much like a suture reaction, or a reaction to the material of her internal stitches. The stitches we use inside the body are absorbable, and eventually break down in the tissues. Sometimes, they can cause an inflammatory reaction when this happens that looks a lot like this. If the reaction or breakdown is too soon, we risk the possibility of a hernia, etc. there is a possibility (smaller but still there) that the suture broke down a bit before it was noticed and with her exertion it just pushed its way a bit more open. If she is unbothered and has not changed in size it could probably wait until your appointment. I would recommend keeping her exercise very restricted in the meantime though-no stairs, no running outside just leash walks, etc. if you are still concerned, you can always call her doctor and see if they can get you in a bit sooner. Hope this helps!

Long story short we had our high strung shepherd spayed in early May. We had issues with the vet and with our dog being so active it was hard to keep her calm. The incision swelled a little we saw a new vet who got us on antibiotics and she's been fi
It looks like there could be some inflammation at the site of the incision. That could be due to her body breaking down the sutures, or she caused some sort of trauma to the area. If she is acting normal and you don't feel any swelling around that area I would wait and see if it improves. But if there is swelling, drainage, or pain I would worry about a dehiscence (opening of the incision) which would be an emergency and she should see a vet immediately.

My adopted cat was spayed on 4/3. It’s now 4/22. I’m a little nervous as her incision site has a little lump by it. I adopted her and didn’t know she had gotten spayed so recently so I didn’t ask why type of after care she was getting. She’s acting f
The incision looks like it healed beautifully. That lump could be a localized tissue reaction to an internal suture. If the lump isn't bothering Stella, it isn't getting bigger or red, and she is otherwise behaving normally, you can wait until her appointment to have her seen. Best of luck.

Help!! Some pink “pimple” looking liquid filled (I think) lumps appeared on my pups suture line just today, it isn’t painful and she doesn’t lick it. She was spayed almost 3 weeks ago with absorbable stitches. Help! Do I need to take her to the vet a
It is not uncommon for dogs to have a mild reaction to under the skin sutures. As long as there is no pain, discharge, odor, or opening of the areas with suture sticking out, it will likely resolve with time. It takes a long time for sutures to dissolve. See your vet if she is bothering the area or you notice any of the signs above. I hope this helps and thank you for using Boop by Petco!
