Tenants left house with bad dog urine smell. Fix?

[Kashif Ali Khan]

My previous tenants who left in March, 2023 violated lease on multiple occasions. Biggest issue is that they kept 2 dogs without notifying me who seem to be peeing in the house for a long time. Loft and stairs have the worst smell while bedrooms are manageable. New tenant is extremely upset since previous tenant temporarily masked the odor; and now them and their familu have to deal with it. 

What is a reasonsably priced action I could take to fix this dog smell problem? Please provide some recommendations.  Thank you.

@Kashif Ali Khan Welcome to BP! Pet odors can be nasty! In my case there was dog urine all over and the PM was not inspecting. We had to remove carpeting and paint the subfloor with Kilz. We ran an ozone machine for a few days as well (people can't be present). With tenants you can't do that so hopefully vinegar and some cleaners made specifically for pet odors-Angry Orange etc will help. There are videos on youtube. All the best!
