Eliminating pet odor from Hades

[Joe S.]

I have a rental that is out of the area. We had to evict some non-paying tenants sometime back and the property manager told me that they had more dogs and cats that I feel comfortable mentioning in an open forum. We hired someone to clean the house,  to clean the floors, painted the entire house and put down floating vinyl planks. The property manager told me that there was an older still in the house. I told her to buy some older absorbers. The older absorbers did not do the job. I ordered and had sent to the property manager a $300 ozone machine. Since the property was only a two bedroom I figured the ozone machine would knock out all odors no time flat. The property manager ran the ozone machine for close to three weeks straight. She has now informed me that the odor are you still there or has came back. 
Is there something that can be done without having to take up the floating vinyl planks and removing the subfloor? I’m open to suggestions.

@Joe S. Your PM was really neglectful if they did not examine the subfloor-it should have been given several coats of Kilz or replaced. Sometimes you have to replace the bottom foot of drywall and new baseboards too. You might try the ozone machine again. Now that the new floor is down I hope you don't have to tear it up. Pets need proper owners or they can be a disaster. I'll be your PM was not inspecting. Mine did not; that's why I know what I know, and she is no longer.
