Eliminating dog pee smell

[Carol Venolia]

I'm guessing this topic has been discussed many times, but this is my first time with this problem, so I appreciate your forbearance.

I have a rental with wall-to-wall carpeting. I had a tenant with a dog. Apparently this dog really liked to pee on carpet. A reputable carpet cleaner told me today that there's nothing he can do to reduce the odor. He said my best bet is to remove all carpet and padding, then seal the subfloor with oil-based Kilz primer before installing any new floorcovering.

Does this sound like good advice? Have any other approaches that have worked for you?

Thank you for any insights you can offer!
