Is your rental " pet friendly" ? if no why not?

@Redgy Saint-Germain Yes. 

I own about ~50 student rentals and it seems like every single one has a black lab puppy. Every. Single. One.

My choices are:

1) Allow dogs and get a $350 non-refundable pet fee.

2) Get $0 and have the students lie the entire year with some variation of "My friend is out of town visiting for the weekend and it's their dog".

I chose #2 for the first 5-6 years and then finally decided to quit swimming upstream. 

They're going to sneak the dog in anyway. I'll take the money.
