i dont have one either, but i am getting one when im older...i would also love to see pics
lots of breeds of dogs chase cars...but i think that catahoulas have more instinct to stalk and chase things than other breeds....i know cocker spaniels and a boxer that chase cars, and they do it for fun lol...too bad they dont know how dangerous it is...one time, my friends cocker got hit by a car cuz she was chasing it...i hope ur dog grows out of it
