Stacy, Orka learned his directional commands by simply walking around the neighborhood and hearing them whenever we came to an intersection or turn. He already knew "Back" from the car when it's time to close the doors / hatch, so it was easy to reinforce it by using long hallways. He knows Up and Load Up so I do not use Back Up but only Back. The hand signal I use for Back is both arms hands extended all the way down below his chest with palms facing me and a gentle shooing motion back. For some reason he barks as he backs. He does it but likes to protest.
Use Head when putting harness over head and Leg when lifting legs into harness. Now when I say Head or Leg Orka patiently makes the moves himself into his harness. He also ever so daintily steps over and between the shafts to position himself for hitching. I say Shaft and tap the Shafts. Soon I won't have to tap.
You'll want to teach Stand and Wait.
Orka's episodes of disobedience are almost always centered around his intense desire to play with other dogs. So I do a lot of distraction training around other dogs and use his desires to help him learn. For instance, he learned to swim across rivers because of his desire to go check out dogs on the far shore. He refused to swim until last summer when I forced him, but I heaped on praise and reassurance and actively used dog park friends to entice him day by day until the light bulb went off and he realized he could use swimming to get what he wants. He loves to swim now!
He watches other dogs and imitates them. So I look for opportunities to train him with other dogs who already know the command or action we're working on.
But I'm pretty much a fumbling newbie and Orka is far from bombproof. But he also does a lot of things most dogs are not called upon to do, and does them very well, and he certainly earns his keep.
I think what's helped most with Orka's training is taking him for walks off leash every day in different places, and taking him to every dog park within 200 miles. He has learned to keep checking in with me, have excellent trail manners, and satisfy his inner wild wolf enough to be trustworthy off leash in almost any situation. This is very helpful when teaching your dog commands from behind.
The service dog article is going to run in print first, black and white, and the photographer said the photos chosen by the editor aren't our 1st choices. Later it will go online in color. She will be giving me a DVD with 100s of photos on it. I am putting together my own service dog photo essay which I'll post here. Just really busy these days to meet the deadline so have not had time to post.
