Qualifying a tenant with a dog

[Randy Lehey]

I'm currently in the process of releasing my duplex and I've never been a big fan of having animal in my unit. I recently had an application that looks good on paper, but he has a dog. I am considering allowing this guy with the dog under the condition that the dog is actually well behaved.

I was wondering if this is ok to do / legal? Can I make offering the unit to this person contingent on if the dog checks out or is that a no no?
