If the inner layers are allowed to heal quickly, hopefully the skin will take care of itself over time.
It was a different vet who did the second suturing and she something about how abnormal cells deteriorate the inner lining of the skin and that is why the sutures did not hold. Honestly, once I heard "abnormal cells" I didn't quite focus on what else she said. I don't have the biopsy report back yet but this doesn't sound promising.
Baron was not doing well when I got him home yesterday. He was obviously in far more pain this time than the first suturing. He stayed in the puppy pen, never making a fuss, but whenever he tried to stand his legs trembled and once in a while he would yelp. It was heartbreaking seeing him like this. I carried him out to the fenced yard several times to go potty but he refused. I think he was just in too much pain. He was quiet in the pen throughout the night and suprisingly he didn't soil it. I took him for a walk but when he started getting frustrated that he couldn't sniff around I removed the cone collar. This seemed to relax him and he was able to relieve himself completely. He's in the puppy pen now, cone collar on, being quiet. The sedatives are obviously working, thank goodness.
