Thanks for the info. I don't have a container for either Frontline nor for Advantage so I don't know what is in them. If any one has the ingredients list and feels like typing it, that would be helpful, thanks.
Since I only have one dog and she is inside most of the time, she does not have a flea problem. I would rather keep using the raw minced garlic in her food since it does seem to work. I can see where if the flea problem was really bad and there were multiple pets, that it might not work so well.
Oh, and Tea Tree Oil is eucalyptus oil, is it not? I do use that diluted with water and wiped on her. Poor dog, she hates it and hides... I usually only wipe her when she has been out rolling in the grass and it helps her to not to get a rash.
I just really hate putting any chemicals directly on my dog, especially when it lasts for a month and when I feel there is no need to do so. And the link to cancer is worrisome and I'd like to know more about that. I am surprised there is not more info on it as this is the first I have heard about Frontline and cancer.
