Motivated by Nothing.
I have a dog/handler pair in one of my classes that is looking for some fresh ideas with her dog... She's raised and handled many Chinese Cresteds, but none quite like this little guy. He's a little.. "off". He has issues with shyness, despite socialization. He's never, ever relaxed, not even at home-- he's always tense, and "folded" looking. He went through a period when he was younger where not even his owner could touch him... And even now, at a year and a half, he hates it.
As far as training goes... He is motivated by NOTHING. He won't take food from his owners hands, even if it's grilled chicken. Won't even eat it off the floor. He won't play with toys, and he doesn't like to do... Anything. The only thing that I can see to possibly motivate him, is lack of touch. He probably would work to lose physical contact....
She's taught him sit, watch me, and even heel through very gentle manipulation... But down has been nothing but a brick wall. I told her since he doesn't like physical contact, teaching him down through manipulation is not a really good idea... But I'm at a loss. I have recommended tellington touch to try and help his tension, and that's going well, but she's very interested in trying to teach him "down".
