I'm aganst the idea of animal infected. It just doesn't seem right.

This.
Another stupid idea I've seen is an infected that's basically a survivor but fights against them, it can pick up guns and shoot the survivors. After I saw that I thought "Seriously? Go play Halo, you newb."

I can hear dog sounds at the end of Death Toll - it was like the rifle fire sounds, background noise I think.
