Join Dr. Jen for the first of a two-part series about excessive barking! Does your dog spend his afternoons looking out the window for things to bark at, or go crazy when he hears a noise outside? Today's episode breaks down the issue of "alert barking" in the house - why dogs do this, and what we can do to calm the chaos when the barking is too much to handle.

Also, a bonus listener question about dogs who hump other dogs during play. Why does this happen, and what should we do about it?
