Aww Roger I'm so sorry you're going through this with Bentley, and that he has to go through another surgery.
Did the stitches or the first surgery cause the hernia, or did he already have one? It's too bad they didn't detect this during the first surgery, so they could have repaired it at the same time. When are they going to do the hernia repair? Please keep us posted on how he's doing, and when he has his surgery.
