These tricks will display as being learned in your Logbook under Dog. They don't appear on the Expression Wheel, if that's what you're talking about. A learned trick will have a green circle next to it, while an unlearned trick will have a red circle next to it. You have to perform one of the correlating hero expressions to get your dog to do the trick. For example, if you come on to somebody with an expression, your dog will perform Beg, that is if I remember correctly.
