visiting dog to my rental- vaccinations expired

[Constantia Petrou]

Hello,

Tenants who recently moved into my Class A property have asked if a friend who is visiting for the weekend can bring his dog in the house. Our tenants have one dog who seems well behaved and with an up to date vaccination record. Our lease doe not allow visiting animals on the property. We made an exception and said we will allow the visiting dog for the weekend if they can provide his vaccination report. I just received the report and the visiting dog's vaccines are past due. How would you handle this? I'm thinking to let it go since these tenants seem good and respectful. Any additional thoughts?

Thank you
