Before commenting, I solemnly swear that I will not judge..
Overall it is not OK to give your dog Taco Bell because it contains a lot of seasoning and sauce that is too high in calories for dogs.
Fresh vegs and protein sauce are generally fine for dogs, with minimal carbohydrate, for example soft taco skin is having less calories than taco chips, so if you want to offer Taco Bells to your dog, choose the soft taco skin. No sauce or seasoning should be added, and try to minimize spices as it might cause dietary indiscretion and soft stool.
Chocodilla from the dessert section should never be given to dogs as it contains chocolate, and try not to give anything with high calories such as fries and mayo sauce. Please don't ask me about soft drinks.
