I’m staying at a house that has the smell of dog ingrained in the carpet.

I’m gonna be here for the next few months but the house isn’t mine. I can’t go somewhere else - that’s not an option right now. What can I do about this smell? I’ve tried febreeze and it doesn’t work. I don’t wanna hire a carpet cleaner cause it’s not my house. So far I just threw an additional carpet over it but it still sucks.
