I haven't started that way before, though I have thought about it. a friend of mine that is a cop in IL did his dog this way, after doing it mostly like I do for a long time. He said it was good for teaching a nose down behavior if you're having trouble with that, but said it didn't do much for him in the long run. So i guess I lost my motivation then. But since i haven't done it this way myself, I'm just throwing things out there and might be completely full of ****. Just FYI a few things that I do for all dogs that I think would transfer well with this too, is food comes on the track. That's it. Do it 4-5 days a week minimum and they eat on the track. Even for dogs that tons of drive for tracking I do this with> I don't think 6 days is that long really or 6 tracks. I do larger scent boxes for 2-3 weeks daily then I do larger scent squares or circles daily for another 2-3 weeks before I move onto tracks, so I have 4-6 weeks of imprinting in before "tracking". One thing I learned is not to quit on that part too soon I didn't read your link, but recognized it from a while ago. Does this do any imprinting like that? or is it small stream of water and food in a straight line to start? It's been a while since i've thought of doing that, so I forget the details. Anyway, I wouldn't get too discouraged, 6 times isn't a lot. There's a lot to work thru. Pairing the water with food, and scent discrimination etc. if you say he's casting back and forth, are you sure to walk that straight line you're spraying with water? both times you walk it? Once to spray the line and the next to place the food? I know with the way I do, i am very careful they don't get rewarded for just casting back and forth down a "trail". At first when there's food in ever footstep it's more difficult, but when the food starts to come off the track it's important they are on the track and tracking in order to move forward to get rewarded. Not sure how that relates to what you're doing, but something to keep in mind as you move forward. also wind. I never, never, never track into the wind when starting tracks. wind is always at my back or up to 90 degrees across a track. Never into it.
