i no longer use it as it didnt work for me. i hate putting the toxic stuff on them but it;s that or fleas. maybe he just doenst like the feeling. if it was bothering him internally i would think you'd see a symptom....vomiting, malase...........not eating...etc. has it been months since you applied a topical?
