I was curious about the Frontline myself and thinking about eventually switching to Advantix, although I have been using Frontline for years and never had a flea problem with any of my past dogs, but there's always a first.
As I stated below, I plan on having Tess checked from head to toe by her vet, we have conversed over the telephone and I have an appointment for Tess next week. Trust me, we will get to the bottom of it, whether it be fleas, dry skin or allergies, I will not leave the office without an answer. Although, on a good note, she hasn't been scratching much at all these past two days, I wonder why.
Freestep, no, there are no red marks whatsoever where Tess has been scratching, I've checked repeatedly, all I see is flaky skin. I have no idea what fleas look like so I could be missing them, although if the white sheet and flea comb really works, there were no black flecks at all, so who knows.
As soon as I get an answer, I will let everyone know. Thanks for all your advice and help.
