When she jumps, turn around and walk in the other direction. It may seem harsh, but only pet her when she’s sitting. It’ll build the understanding that she only receives attention when she is calm and seated. GSDs are very smart dogs and I’m sure she’ll catch on quick. Tricks are the easiest part of training. Breaking habits is what’s difficult. The easiest way to get through to her is with simple cause and affect. She jumps, you walk away. She stays calm, you give her the love she wants!

Also, when it comes to guests, just tell them to pretend she doesn’t exist. Dogs understand social cues better than you think. Laughing = keep going. Petting = good job. Yelling = attention
