English Bulldog tried to attack pizza man

Okay, this does not need to become a tragedy. She's not a bad dog and you aren't a bad person. You are just in the beginning of your relationship. I would, right away, sign up for an obedience training class with her. You and she need to establish that you are the boss, and she is the dog, and she does not need to be protective of you to such an extreme.

Obedience training is as much for you as the dog, and just because she is older doesn't mean she cannot learn! Bless you for taking on an adult rescue, and let us know how things work out. In the meantime, you can gate off her access to the front door if someone is coming by, just to prevent tragedy. Keep her on a leash even inside if you are having visitors or delivery people, and keep her focussed on you if she starts getting tense.

With ANY animal, and especially a rescue, and a new rescue at that, you simply have no idea what her past was. I wouldn't consider rehoming her because of 1 incident with a pizza man. What is interesting to me is the aggressive behavior after the food delivery. This sounds like a training issue all the way. I hope you will reconsider.
