How do you get dog urine smell away?

Ok- if the urine smell is coming from the floor inside the house... you must pull up the carpet /wood or laminate floor - get it down to the slab or the subfloor- use a bleach/water solution on the slab or the wood subfloor- let dry- then apply Kilz Oil based primer several coats- you can also replace the area of subfloor that is urine soaked- with new plywood subfloor- if you are on a slab- seal the affected area-with kilz= once the kilz dries- you can re-install any flooring over the area- if the pet stain/smell is on any thing else- bleach/and water and Mohawk flooring essentials odor control spray will neutralize the odor!
