gee do not think I would bother,,, imagine you would have to toss more than you sell…also they would have to be cooked in a seperate conatiner as those folks will not want anything that might be tainted by a real dog

 
I agree, in the 5 months or so I have been selling I have been asked once maybe twice about a veggie dog. Asked about a turkey dog a couple times also.
 
It is about demographics, so if you have the demopgrahic and demand then go for it, if not I would not try it just to please a few people…..
