The tenant had been complaining about a fear a branch from the tree might fall on her 5 pound dog.

My primary care physician wrote a letter explaining why my dog would help me live in my unit more comfortably, in spite of my disability.The place I live in, however, does accept dogs, and my dog is only 22 pounds.  

They must have renter's insurance, no pit bulls , etc. max of two pets, less than 25 pounds.
