Lease renewal w/ a dog who will be left alone while the tenant is

[Joe C.]

Last year I rented to an unmarried couple. The lease was in both names and I allowed a dog because one tenant did nor work and was staying home with the dog. The rental is high end and sort after.  I live in a different  state. Their lease ends on 12/31/22. They asked for a 6 month extension. 1 month ago i sent them a new lease for 6 months. They have not signed it. Today i was informed to remove one of their names from the new lease because she moved out of state. I asked the tenant who is staying about the status of the dog and was told the dog is staying with her. She works full time meaning the dog will be left alone for a good portion of the day. i am not comfortable with that.  I know if I give her notice that i am not renewing I know she will stay regardless.  My state allows for 7 day notice if one does not renew. Any advice is welcomed.
