I have tried everything with Duece trying to train him not to jump on people. He does it with my husband, son and any new person he meets. I have tried holding him in sit position when people first come through door or want to come up and pet him and he does good until they get right to him and then he jumps and usually scratches and draws blood. I have tried having people ignore, have tried lemon juice sprayed in mouth (thinks it's lemonaide), and have tried pennies in a bottle (thinks it's great new toy). He is getting bigger and bigger and it's getting harder and harder to keep him from jumping. He does not do it to me and does not do it as much with husband and son as he does with new people. Any idea's? Also, how can I teach him to be more aloof with strangers instead of acting like they are his best friend? He is 4 months on Friday.
