Why is my dog's spay incision still scabbing after 6 months?

It is only possible to attach picture via private consults, which you can have with any of our online vets. from your description it's probably the knot underneath the skin (where the scab is) that is bothering her. these knots take a little longer to dissolve- it might take up to 4-5 weeks to dissolve completely, nut as long as the incision is closed i wouldn't worry too much.

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

Based on the photos you provided, I would highly suspect that this is from a burn (temperature or chemical). If your veterinarian used heating discs, a heating blanket or a heating table during surgery, the temperature may have been too high and could have lead to these burns developing. I've seen this happen at my clinic where a technician used a blow drier to heat up a patient because the temperature was too low on the dog and the dog developed severe burns. I would treat them as burns (antibiotic therapy, pain medications and keeping the area clean) and wait for the scabs to fall off and the tissue to heal. I would seek a second opinion from a dermatologist as well in regards to this and whether or not Laly should be on immunosuppressant drugs for this as it may be a condition in which these are not needed. Again, the location, pattern and appearance have me suspicious of a burn. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

This is probably happening due to an allergic reaction to the suture material, it is quite common. these sutures usually dissolve completely within 4-6 weeks, which might be the time it will take to resolve.

Poor girl. She does apear to be taking a while to heal. If pus is present, then that is the reason for the delay in healing. The infection is not being controlled well with the antibiotics chosen. Another stronger antibiotic is needed here, so discuss this with your veterinarian. I do also see some granulation tissue there which is when the skin is trying to heal and close the incision. The wound still looks pretty fresh though, even though its been 3 weeks now. Based on what I see in the photo and your description, hydrotherapy of the area may be needed at this point, possible reclosure of the area with additional staples once these are removed, and a different antibiotic. I hope that this helps and best wishes getting this area to finally heal. Take care! : )

Actually, it could be stitches, depending on what kind of material they used for that layer (we close abdominal incisions in 3 individual layers). Or it could be scar tissue. Either way, if it isn’t causing any issues, just let it be! :) If it seems to be causing discomfort or swelling, then it needs to be examined by a vet.

Thank you for providing a picture of Honey's incision, it's very helpful. Yes, I agree it does appear to have opened up, and I'm worried it could get infected since it has opened. She needs to see a vet asap to get this closed, and the vet may likely close it with surgical glue after examining it and cleaning it. The vet may also prescribe antibiotics. Please take her into a vet immediately. I hope this helps!
