I do think he'll be OK once the stitches are out, the cone is off, and he can really feel at home again. He's still spending most of his time crated to keep him from trying to jump onto the desk (which he wants to do every time he's out of the crate). I don't think he can make that jump successfully with the cone on, and I can't risk him falling and tearing those stitches.

I've been picking him up and putting him in his box on the desk from time to time (with one arm around him to keep him from jumping off), but he can't get comfortable there with that cone on. So he's frustrated, and he still hurts.
