Public Land hog hunting?

according to several game wardens, bowie county and bell county wardens. dogs are considered legal means. the reason i was given from both wardens as to why dogs are not listed as leagl means is because hogs are considered an exotic. if anyone else has anymore info on why dogs are not listed as legal means, please chime in and let us know. on public land caution should be takin if hunting during the day, but as it is stated PUBLIC land is there for all to use including hogdoggers. i hunted during the daylight hrs just b/c i have all legal rights to the area too and where i hunt, it is a 1 way in and 1 way out. wont be hard to find out who did it and also block the road till the warden gets there.
