It is very hard to get any animal urine smell out of surfaces. It depends on the type of wood floor you have- I found something that I ordered off a infomercial called urine be gone, I have tried it and it works great, it is for all surfaces and carpet and for all urine ( animal, human ect...) it will totally get rid of the smell and any stains. You can order it online.

I agree 100% this stuff is amazing, I even used it on our garage floor it gets rid of the urine and smells great works instantly,

-Hey I found this at a local Pharmacy (Walgreen's. It was 19.99 and it came with a black light! It is good stuff!

@daren 1 is right, vinegar is super for taking the urine smell out. Or white wine. I say, drink the wine and use the vinegar........

Usually easier removing floor versus smell of urine.

Have it replace with laminated flooring. and train your dog were to do his thing.
