Getting urine smell out of hardwoods?

[Cristin Andrews]

Tenant has allowed 4 (non approved) dogs to pee all over hardwoods in house. Tenant is leaving soon and so I am looking for advice on how best to get the smell out of the hardwoods. It is overwhelming smell from the door. I haven’t been able to inspect it enough yet to tell if there is water damage also. Am I going to have to rip the floors out?
