What oral pill do you have him on? There can be a lot of problems with Advantix. We're you told to use both? Any sign of a hot spot above the tail?
Just to check, get a flea comb and see if you pick up ant fleas or flea dirt. This time of year, it could be a sensitivity to something outside.
First, it is not recommended that you use two flea treatments at once on the same dog. This can cause toxicity in the system and make him sick. As far as the itching out of nowhere, I recommend seeing your vet, as he could have skin issues that cause itching. Blessings - Blu
Thank you Karla. I have to tell you that when I saw the picture of your dog and the name Karla, my jaw dropped. My best friend Karla has the same exact looking dog!!! But it wasn't. As far as Billy is going.....he doesn't violently start itching his booty like he was. I made a mistake saying he was on Advantix II. He was on Advantage and started the Advantix two days ago. I stopped the oral one. I took the advice from a worker on the floor not a vet. Pretty stupid, hugh. I got him a prescribed conditioner too. And I actually burst his anal glands. They showed it from detail to detail. An boy were they full! YUCK Thanks again for the advice. -Amber
