Boy I have seen some atrocious behavior over the years regarding dogs and some tenants and owners for that matter... be it staking them in the yard in 100 degree heat to. hoarding them and such. 

Be prepared for some unwarranted behavior, such as districting of amenities.

There is a rough backstory  -- tenant has been a PITA since day ONE and her attitude and behavior are continuing to escalate.  

Set a good example for your children because when they get older, they will model your behavior back to you.

What I usually explain to tenants is I am not responsible to control pests that are potentially caused by tenant behavior and I don't control the outdoors.  

Do not reward bad behavior.

If she acknowledged, in writing, or by her behavior, that she got "notice," then she got notice.  

Reporting suspicious behavior is not only ok, it's your responsibility.

So in other words you are rewarding bad behavior, and then when they come to us, we have to deal with it.  

I know that I am loosing money on the occasional bad guys but this is way better than loosing money on 50% of my rentals and the bad tenants get reported to the courts and hopefully when the next landlord checks their background he/she will not rent to them so they'll pay for their bad behavior.
