Search & Rescue Dogs

I have a 20 month doberman who has been tracking for about 6 months now, doing great. About three weeks ago he was kinda accidently introduced to cadaver. Now he has almost completely reverted back to the very beginning of our tracking training. My group thinks that since he has a new found fascination with cadavr I should just switch from tracking to cadaver. I really love tracking and he was doing so well before the cadaver Incident. Help.

How sure are you that it was the cadaver incident that stopped his tracking? just because he had a cadaver "incident" it doesn't mean he will be better suited to that line of work. Unless you have a very experienced cadaver trainer that has seen a natural dog then stick with tracking.
As with all dog training when you get a blip, take him back a couple of stages and get him enjoying the tracking again, I don't know how you end your track but why not end with a bit of meat, 49p hot dog sausages are a dream to teach a dog how to track, but no ketchup
