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.
