Dardel, that's encouraging news! Maybe it's early and they can simply treat it! I hope so. Found this with some good info.

We were always overly protective with Buster after he recovered, but noticed nothing unusual. I haven't read all this information yet but so far haven't learned of any long-term effects.
Let us know how it's going!
