Vet just called back. Not very much help.
He says he doesn't see that many dogs have this reaction, but sometimes he does get a call that this has happened. Says he really can't explain "why". Sometimes, it's the fleas that run to their head area after administering that is making her feel uneasy. Honestly, I think I've seen 1 flea on Bella when gave her a bath in Dawn last week?? I know she can have a reaction from just 1 flea bite though. He wanted to know if she was vomiting, diarrhea? But so far, No, thank goodness. Hope she doesn't get worse
