I just smile and say " You know, you might just be right" and finish the rest of the sentence "but not a chance this time, you bumbling idiot" under my breath. When you allow them to form the opinion that you "agree" they will shut up and toddle along and go bother someone else who they can harass. Once they are gone, give your dog a big ole hug and explain to him or her that is why dogs eat their young so they can avoid having stupid members of the pack out loose in the world. Dogs are much smarter than we usually give them credit for, who else reads posture, body language, tone, temper and attitude with not one word spoken. And live to love their person and do what ever they can every day of their life to make that person happy they are in their pack. I cant think of a better friend in the whole word to have around. Too bad people aren't loyal and driven to do the same things as our animal friends. Think how nice the world could be. So don't let the idiots ruffle your feathers, they are just stupid and have no clue what they are talking about. I wouldn't take job advice from an idiot and I certainly wont take training advice from them either...
