I'm having difficulties teaching Miles to cop-cop/put his feet on mine. He's a Corgi, so he's short, and his feet are even shorter. Another disadvantage is that he's really long. His legs are just to stubby to reach both of my feet! Also, he seems to still be uncomfortable between my legs. Only if I have a decent-sized treat will he finally decide to come, and he scampers back as soon as he can. I have had four training sessions teaching him the cop-cop, and he's not making progress. And I have to lean down all the way every time since he's so short. I get lightheaded a lot. Will he ever be able to learn it, or is his body structure preventing him?
