If I do have a door to door salesman stop by my house I always have my dog at my side most of the time the dog scares them off. Not because she is barking but mainly due to her staring at you intensely and following your movement with her head.

THey have absolutely no right to do that. It's a severe breach of privacy. They have no legal right to do that.
I'd tell them to fuck off, like all other scammers.

They absolutely do have the right to do that, its not illegal.
I could walk right up to you and ask for your credit card number and social and its not illegal.
No one is making you give them the info they asked for.
