What, for money? Sue him? I doubt it very much. My medical care is being paid for by Worker's Comp insurance, and I am apparently not disabled. The dog's owner has been a stand-up guy thus far, staying in contact with me and making sure that I am OK. I believe he is genuinely concerned and not just covering his butt legally.
If I had suffered monetary losses, or loss of income or earning potential, or been permanently disfigured, I might feel differently. But I have practically no pain and only minor hassles to deal with - such as an antibitoic that is giving me a gnarly case of the trots 
I know the dog owner is mostly worried about you coming back at him for claims against his dog.
It sucks that happened and it especially sucks that it was a rott and then everyone has to think.. what if... with their reputation...
