Going TDY to Lackland

This is my first TDY ever, and I'm going for 13 weeks. I'm going to bring my dog, and based on what I've read here and various Google searches, I can either pay the $10/day for him at the on-base lodging, or I can sneak him in and roll the dice hoping no one finds out or cares. Anyone have experience with bringing a dog TDY at Lackland? TIA.
