I run into a lot of clients that can't say the word "walk" in front of their dog because of the reaction they get. However this is something you can easily fix.

Start by just saying the word "walk" in a normal voice and don't do anything or even acknowledge your dog. Wait for him/her to calm down from it and say it again. Wait for him/her to calm down from it and say it again. Repeat these steps until your dog has no reaction, problem solved.
