Most of the non canned exotic hunting is in the Hill Country. In July I would be looking for good swimming holes but some ranches have hotter than hell discounts that time of year.

Check the roster of the Exotic Wildlife association to see if any are in the DFW area. https://www.myewa.org/

Lots of options around Kerrville and West Tex. is the place for a truly free range Audad hunt. Magnum Outfitters in Eldorado can fix you up there. I have not hunted with them but he is the brother of a long time friend and has a good reputation.
