Hello FML, Have any of you had trouble w fleas resisting medication this year? A friend in Calif on the OR border, and I here in Ethiopia, have situations in which fleas do not die on standard treatments. I use Revolution here, and she uses totally different things (not on ferrets) including powders and flea bombs. I have two small dogs on which the Revolution does not work. Especially one of them, a fully-haired Chinese Crested. The other animals (my other dog, my cats, and my ferrets) are fine. (The donkeys too, though I have never seen fleas on them and don't treat them -- maybe herbivores don't get fleas?) Since these two locations are so far from each other, and our treatments are so very different, I am wondering what might be going on. [Posted in FML 7363]
