Even though he needs a home fast, please ask her to charge a fee, even $10 would deter "bunchers". (people that take free to good home dogs and sell them for research). It does happen, and these people pose as wonderful families, even sometimes bringing children. Tell her her she should also screen the adopter, to at least make sure he is going to a good home, and not just pawn him on the first person that comes along.

Good luck.
