First of all, the excessive bathing and the flea collar could start to create additional problems with dry skin and itchiness.
Keep vaccuming and combing, and I personally reccomend Frontline Plus, as Advantix and Advantage make my dog sick, but some people have said the same to me about Frontline.
Also, not to doubt you, but since there is not evidence of fleas, are you sure it isn't just dirt?
