Dog ACL surgery recovery: inflamed sores on scar line, what's next?

Depending on the type of procedure he has done it might be a reaction to one of the implants. I would consult with your vet about your options to have it flushed and debrided and cultured or having the implants removed if able

One of the main problems here is that your dog is licking the incision. The licking causes microscopically small injuries into which your dog licks bacteria. These bacteria cause infection and pus to form. so it is important to keep the dog from licking by preferably putting an e-collar on Kat until the incision is completely healed. If your dog keeps licking even after it is healed then you need to take Kat to your vet for a recheck as there may be pain or irritation that entices Kat to lick.

The site is inflamed and this may be a tissue reaction, at the site of the previous injury. I would suggest to have it checked as there may be even a piece of suture material still inside. It is difficult to give you more specific advices from the picture as a physical examination would be essential in this case to be able to determine what is going on.

I'm sorry Brutus had to have surgery for his CCL recently! From the pictures, it looks like it's healing well at the moment, and I'm not seeing any sign of infection. It's normal to have a slight bloody discharge, and I would be concerned if there was pus, or if the incision was red, swollen, or warm to the touch. Should you see those signs that I've mentioned, that indicates infection, and I would take him into the vet. Hopefully he continues to heal well. Good luck, I hope this helps!

Unfortunately I'd guess that this is an implant failure, and the symptoms may not resolve until the screw is removed. I'd recommend rechecking with your vet to see what they would recommend next. It's possible that a different surgical procedure will need to be performed, or your vet might want to try getting a culture of the wound and a longer course of antibiotics.

Place the e-collar back on him. Have him rechecked by your veterinarian. He may need a few more staples to keep the site fully closed. Consider Bitter Apple Spray, Fooey or other deterrent ( https://www.petco.com/shop/en/petcostore/category/dog/dog-training/dog-training-repellents-and-attractants ) around the site to further prevent licking. A cold compress applied for 10 minutes 2-3 times a day may ease any discomfort. Continue to restrict activity to just leash walks for eiimination.

It is hard to tell from the picture - heat, redness, discharge , smell and pus would be the red flags most concerning. A small bit of swelling and blood spots is not uncommon but a post surgery recheck to monitor her temperature and signs of infection would be recommended for safety as infection could cause problems in the longterm
