I have a 12 month old GSD that I can’t get to jump (into the back of the truck, etc). He is very smart and does everything that I ask of BUT just won’t jump. Any advice?

A question which probably does not interest many but here goes.... I have a great GS who was trained to be a guard dog (not by me). I am disabled and my service dog died so this dog needs to change hats. He is doing well with people interactions but he has on occasion barked at a patient, my medical pt. So: how do I correct this behavior without destroying his protective nature? And an additional question, he is very smart and is bored with reg. obedience - my impression - he is near perfect. So some to work on but since I do not have the time to engage in schutzhund, agility or such are there some neat training I can do with him. I have almost found him a new home because I felt like I was not providing enough stimulation like ...."Teach Your Dog 20 Tricks" Joking but serious. I thank you for your consideration. And I am a regular reader of your newsletter.

Thanks,
