Anyone bought used rig with musty smells or dog odors?

I would never buy anything with cigarette odor. This happened due to someone smoking and getting into the car immediately over a period of time. It got to a point where it was making me ill so I tried the ZorbX.

I have no.experience with pet odors so I am not sure what causes the odor....whether it is urination or just a dog living in it. If it is urine then I guess tje carpet.and.subfloor.would have to be replaced. I don't see how a spray would take care of deep issues like that.
