I know this is a terrible time for fleas, but please Google flea dipping hazards before choosing to pick them off one by one! My sister just flea dipped her Cocker yesterday...he seemed a little sore but then was fine (eating, drinking, barking, walking stairs). She is rushing him to the vet RIGHT NOW as she thinks he is blind! Please pray for Max, my sister is quite hysterical

. Has anyone had reactions to flea dipping their pets before?
My sister used Hartz. Googled it afterward and found how poisonous it is.
