Washington Post today carried this tidbit about a scientist who tried to determine if we really do resemble our pets, and if so why:

The researchers photographed 45 dogs and their owners at three dog parks and gathered information about the breeds and how long owners and pets had been together. They then asked 28 students to try to match the people to the pooches.

The results suggest not that we grow to look like each other, but rather humans on some subconscious level choose animals that resemble themselves.

Bah. I have cats. As long as it doesn't puke, pee, or crap on something I own, I'm happy with it.
