Do you have an itchy dog?

First, you are most certainly NOT alone.

Next, here is some really interesting research out of the University of Pennsylvania on the topic of atopic dermatitis: "Penn Study Points to Path for Antibiotic-free Treatment of Atopic Dermatitis."  They did some studies on how the skin's bacterial population affects dogs' health, which is interesting because there is quite a bit of work being done on how humans are affected in the same way (see this New York Times Magazine article, "My No-Soap, No-Shampoo, Bacteria-Rich Hygiene Experiment").
