I too have had and still do have (although its getting better) the same problem. Jett gets so excited that she jumps up on me, hubby and son
he's 4 tomorrow! I was told my my trainer at the rotty club to drop her every time she jumps. Now whenever she tries to jump i command her to drop both vocally and with hand signals, you've never heard such a thud before when she drops....but the drop only lasts about 2 seconds and she's up again, so i just keep repeating it until she's calm and rational.
Yesterday i can honestly say she jumped up at me about 4 times during the whole day, which is a significant decrease. She is learning now that its an unacceptable behaviour - i never went through this with my other rotty's, but each dog is different. If you are consistent with your dog he will stop. Jett is 6 months old in 4 days and this has been going on for 3 months....but as i said it IS getting better and their IS a light at the end of the tunnel!
Good luck!
