Things you need to get started:
Find a big open grassy area with not a lot of people to start with. Your yard doesn't work well since it's already covered in your tracks. To begin with, either have your dog in a sit stay, in a kennel or tied up somewhere that they can watch what you are doing. Pick a landmark like a tree to make a straight line from where you start. Put a flag in the ground at the start line. Place a piece of string cheese at the start. Taking normal steps walk in a straight line toward your landmark placing a piece of cheese in every footstep. Don't make it too long at first, maybe 20 or 30 feet. Put the leather glove at the end of your track and put some pieces of cheese in the glove. Place another flag at the end. Then walk straight another 10 feet or so and make a wide turn to come back to where you left your dog, making sure you are well away from your track.
You are supposed to be well behind your dog, and in a test I believe my teacher said you use a 30 foot lead, but I just used my 6 foot leash to start with. Amber immediately followed the track, vacuuming up cheese.
When they get to the glove at the end, throw a party! Give them treats out of the glove, make the glove very exciting. In a test they have to indicate to you in some way that they have found the glove, by looking at it or they can even pick it up and give it to you.
Apparently some dogs like the tracking so much that they don't stop at the end of the cheese trail, they keep on sniffing past the glove, so don't encourage that since you want finding the glove to be the rewarding part.
Don't put any turns in your track for a little while and start with cheese in every footstep, slowly working your way up to every other footstep, every third step and so on.
I got very excited about this! Can you tell? It sounds so simple but it was a lot of fun watching her sniffing the ground and wondering what she was smelling. I know in the beginning she is just sniffing for the cheese but just imagine your dog tracking a 400 yard track that has been aged for an hour in the rain and wind with who knows what else having crossed that track and you are just holding the leash, trusting your dog...
