If your dog exhibits any of these symptoms, it could be a sign that the incision is not healing properly. Keep an eye out for the following signs of abnormal recovery after surgery on your dog: • Excessive swelling or redness following neutering • Healing of a neuter incision • Dissolvable stitches for neutering • Inability to urinate or pain while urinating • Odor or foul odor emanating from the incision site • Excessive squeezing (or any draining if the incision site was completely closed)
