Scenario 1: The wood floors need to be refinished because dog urine has ruined them and the pet deposit doesn't completely cover the damage.

One of my favorites is cat urine.

What I see that is to the side of your photo is staining from wetness; if the staining is urine, then you will find that upon refinishing the floors that there will be a darker stained area where the urine was.

The biggest hurtle You had better have a recent track record of doing some profitable deals.

Ordinary cleaning wasn't going to get the stains and the urine out of the carpet.I assume that the dog did that, and not the tenant :D You can ask for an additional pet deposit, but it's unlikely to cover the added cost if there's major replacements to be made.

it's about a monthmy concern is not the physical damage to things, I'm afraid a dog this young is likely to urinate all over the place.

The smell of amonia from the urine is almost impossible to get out of sub flooring especially OSB and partical board.

At first I thought the floors were warped from the tenants dog ,that they were not suppose to have, since there was urine stains every where and I thought the sound of the water running was from  a shower valve.

Pictures HereIt reeks of pet urine, which I don't mind cleaning up, but curious of how much additional costs that would factor in.

I do not because I don't want to deal with the inevitable damage that comes with animal urine, scratching/biting and liability from renting to a pet owner.
