$250 Fine for Pets?

I picked up my rental today and was talking to the lady and offhand mentioned I’d be bringing my dog. She stopped and said I couldn’t do that unless it was a service dog, otherwise there would be a $250 fine. What? I got home and looked on their website and found where it literally says they’re pet friendly, dogs just must be crated and free of pet hair.

I’ve seen people complain now that they were charged over just a couple of pet hairs in the car, which seems ridiculous. I’ll have my dog crated and plenty of towels down, so as long as I vacuum it before return, how concerned should I be? I mean my clothes get dog hair on them at home, so it’s possible those could get on the rental even if I didn’t have my dog, so I don’t know how they’d enforce that.
