Trust me guys, 50-50 water vinegar will do the trick in short order.
My ex-wife is a professional dog trainer. In addition to our six pets, the house always had four legged guests, many of whom weren't house broken. Nothing worked until we found vinegar.
For those living where it gets hot, if you notice an odor when you walk in the door during hot season, the suspect may well stank coming up through the drain. The P Trap is supposed to stop that, but doesn't always. Baking soda is the answer to that - just put some down the drain.
