Why is my dog's neuter incision hard with stitches still visible?
Hello, thank you for using Petco Pet Education Center, formerly Petcoach.
Neuter incisions are closed with two layers of stitches. Your vet only removed the outer layer of stitches. The inside layer is never removed and will eventually dissolve. There is still a chance he is having a suture reaction to the inside layer. Typically this will resolve on its own over time with no treatment. Occasionally, if the issue doesn't resolve, a second surgery must be done to remove the old "inside" stitches and replace them with a different type of suture material.
I suggest you keep a cone collar on Cosmo until the issue is completely resolved. If he licks this area too much this will cause a severe problem, a possible infection and he may even open the incision. I don't recommend you put anything on the incision. It's best to leave it be.
If the swelling gets worse, or there is discharge from the incision then he definitely needs to go back to the vet. If Cosmo is very uncomfortable then you may also want to take him back to the vet so they can prescribe an anti-inflammatory for him.
Hope this helps. Best wishes.
