Pet policy criteria for tenants

[Pradeep C.]

We have a prospective tenant who's Girlfriend will visit him every other week and maybe stays a day or two. She has a pet(dog) who will be with her during the time she visits/stays at the rental property.

The GF is not a co-applicant but just visits him and stays a day or two.

How do I address this situation since we have a "No Pets" policy in all our rentals.

Should I charge a pet fee every month along with a pet deposit or should I say "No Pets."

Please advise.

Thanks!
