I am glad to hear Maximus is home, and on his way to recovery. Well, sleeping is probably the best thing for him right now. I know it is very hard to see your normally happy dog acting like he hasn't got a clue what is going on, but it will/would be hard trying to keep him calm while he is healing if he weren't so out of it. I didn't know that poor Maximus didn't take well to be sedated. Poor baby. Big Hugs to him and you.
