How do I get the smell of dog pee out of my house?

Tonia, it is probably coming from the subfloor. Can you pull up that area of flooring? If so, you need to seal the area that has urine with Kilz. That will stop it from migrating into the new flooring

You must use an enzyme cleaner that targets urine. I use Nature's Miracle for Cat Urine - I presume it will also work on dog urine. Buy a gallon of it from any large big box pet supply place or Amazon and use a black light in a very dark room to detect where the source of the smell is coming from (corners, behind the couch, etc.). Once you fine the source, POUR on the Nature's Miracle. Don't squirt, don't dribble, POUR it on - really saturate that area(s). Best wishes. Urine smell is the worst.

Natures miracle! Otherwise Kilz on the subfloor.

I use full strength vinegar to saturate the area and then some. When it dries, give it the sniff test and repeat (it is dry when you don't smell the vinegar). The vinegar can really soak into fabric, wood, anything porous, as does the urine and it can spread and seep all over the place.

you also need a transition strip between the door and the floor to block odors coming from the subfloor. light scented candles when you have guests.

Clorox urine gone works great. The active ingredient is Hydrogen peroxide. I have used peroxide to clean my bathroom after "boy's". Cleans, sanitizer and gets smell out. Also used after the dogs piddles too.

Hi Tonia, hope this helps you out,
