I've had my dog for several weeks now and I've been fine. And then yesterday my hands and my neck started itching like crazy. Yesterday I gave him a haircut so last night I thought it was because his hair was flying around. But today...after I washed his feet after taking him for a walk...I started itching again in the same spots.

And yesterday I had also started taking these diet pills. But if I was allergic to it...wouldn't i be itching all over and not just those two areas?

What could this be?
