Met tenant smoking & pet in the house

[Tracey Williams]

I stop by one of out rentals yesterday to see the plumber's work. i met the tenant smoking in the living room and heard a dog barking upstairs.

We have a no smoking & pet policy in our lease.

I told her both her not allowed in the units and she lied that the dog belongs to her mum and she took the dog out with her while I was there. I can tell that she was lying and my plumber confirm that he saw the dog there the previous day.

What should I do next? Send her a warning letter of violation of the terms in her lease?
How do I ensure she is still not smoking in the house?
Thanks for sharing for view
Tracey.
