He may be able to recomend behavior therapy that can correct it, or atleaset control it.
Good Luck!

We got Carl when he was a little over a year old. Anything could have happened in that amount of time

Like you said, the reason he probably doesn't like these people is that he has had a bad experience with someone like that before. The thing is, I don't know what it is about these certain people!

I'll check into the fear thing, Sue. That could be it.
