Why don't you board your dog?? It would probably be less expensive than paying the airline the pet fee--I think its $50 each way depending on the airline.
The more the merrier at Convention!!! You should come!! You probably need to make your plans now though. Airfare is not cheap into San Antonio so the more time you have to plan, the better. Additionally, I think we're coming up on deadlines to the hotel for rooms and food, etc.
I'd offer to let you keep your pooch at my house but I have three dogs who would probably count him among their chew toys.
