I would get an estimate for steam cleaning the entire space and offset the security deposit in that amount - sending her the required documentation. 

I spent countless hours steam cleaning to get rid of dog smell before; I haven't switched carpet over to LVP yet which may be most of the problem.

This is a A- unit renting for $1700+ with a max of 2 dogs.For units with carpets, I ask tenants to have it professionally steam-cleaned and provide the receipt.

vaccumed a dozen times and hired steam cleaner.this is how much dog hair came up from putting a piece of tape on the carpet.dog hair floating around, especially under aplliances and utility room.stove was filthy, and oily film above on microwave and cabinets.permanent oil stains in cabinetvinyl floors were filthydamage to appliance. 

After listening to the new boilermaker (the new boilermaker, hired incidentally  by the principal because his wages were low and fit into his budget better) and asking a few additional questions, he went to the boiler room looked at the maze of twisting pipes, listened to the thump of the boiler and the hiss of the escaping steam for a few minutes, and felt some pipes with his hands. 

Check that the water heater isn't leaking If you have a steam boiler, I've seen the return lines run under slab of basement and rust out draining boiler and making it constantly refill. 

Two new gas fired steam boilers (one for each unit)2. 

Full steam ahead though and learning as much as possible along the way.

The landlord sent pictures of mold that was in the bathroom and claimed it was from the steam of the bathroom with the door shut after use however in march 2020 they discovered mold in the living room form the HOA showing negligence with the roof.

I will certainly reach out, if a project gains some steam.
