Tenant gave notice & now got a dog - how would you play it?

[Lewis Christman]

A tenant gave me notice and I confirmed it and posted a letter on the door as well as sent certified letter.  She has broken the front door and basically messed up the unit.  She is to be out at the end of April.  Now she has gotten a dog (or one of the people she has staying there has a dog) and they let it run loose apparently (I just found this out last night).  She does not have a pet addendum.  Do I file eviction paperwork for this or let it ride with the end of the lease (hoping she is out).  If anyone wants to share a letter they would post / send please send it to me.
