Red bumps on dog's spay incision 11 months later: Should I worry?

This appears to be healing just fine. I suspect this is a mild reaction to the stitches under the skin. This is very common. I would only be worried if it opens up and starts draining fluid, gets much larger or becomes very red. Just make sure she cannot lick it until it is completely healed.

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 Petco Pet Education Center, formerly Petcoach!

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.

Overall, Darla's incision certainly looks as though it has healed well. The suture material used under the skin can take several months to fully dissolve. In that time, some dogs may develop mild inflammatory responses. There is also a chance that Darla has developed a skin infection from other causes (most commonly underlying allergies). At this point, you can continue to monitor these bumps at home for changes. However, if they worsen or seem to cause irritation with licking or itching, Darla should go to her vet for further evaluation. If she is licking, keep an e-collar (cone) on Darla until you can take her to the vet to prevent further skin irritation. I hope this helps and that all goes well!

The sutures take months to fully dissolve and it may be a reaction associated with the remaining suture. It could also be unrelated and be a bite wound. It seems very inflamed and possibly infected. I would have your vet check it to see if antibiotics are needed and what the cause is

This is a pustule probably from a buried suture knot. The suture is absorbable but it takes several months to dissolve and sometimes the knot can cause irritation and a small infected pustule. I recommend taking Patti to your veterinarian and they can feel if there is suture left in the incision. It can be removed now that the incision is healed. Generally when the pustule is opened the knot is exposed and can be cut off and removed with suture scissors. Then the skin will be cleaned and it should heal up quickly once the knot is gone.

This doesn't look perfect but definitely does not look too bad either, there is some bulging as you mentioned, probably because the stitches have been put on a little too tight, as long as the stitches hold though i would not be too worried, you need to make sure she does not lick the area (i assume she has an E-collar on) and make sure the incision does not open up, the swelling should start resolving within a couple days from now. as long as it does not look worse than this i would be ok keeping her at home, you can still take her for short walks without any issues and your vet needs to see her at some point but it is not urgent (usually post opps are done 3 days and 10 days after the surgery).
