Hi Emm, I am sure there are other ways of teaching it, but this is how I do it.
The idea with secent discrimination is that your dog will find an article that has your scent on it from among other, unscented, articles. You need to make a scent board. Get a piece of peg-board and four lenths of dowel (about 4" long). Get someone to wire three of the pieces of dowel on to the board. (If you have to wire them on yourself then leave the board outside for at least 24 hours so that your scent disappears from the wired articles).
When you are ready to start scent the other piece of dowel by having it in your hand or next to your skin somewhere (use your imagination
) for 10 minutes. Show the articles to your dog. Let him sniff it and hold it in his mouth. Place the scented article on the board. Tell your dog to 'find'. He won't be able to pick up the wrong article as the others are wired down. As soon as he picks up, or noses, 'your' article praise him and encourage him to bring it back to you.
Practise with the wired articles for several days. When he is consistently getting it correct then remove the wires and see if he will still select the correct article. If he doesn't, don't reprimand him for getting it wrong, go back to wiring so that he cannot make a mistake.
Once he is solid with the board then move the articles on to a different surface, e.g. a towel, the grass, carpet, etc. Remember, NEVER touch the articles that you do not want him to retrieve. Use tongs to set them out. When he is getting the dowels correct then you can move to different types of articles, gloves, pieces of leather, metal articles, etc. It doesn't matter if someone else touches the articles so, for a 'party trick', you can ask people to place bank notes on the floor along with one that you have scented and send your dog to find yours, or he can pick out your hat/shoe/glove/hankie from among a pile of others.
Dogs usually enjoy this game as they get lots of praise and rewards for doing what comes naturally - using their noses. If he picks up the wrong thing at any time do not tell him off - the lack of praise & reward is sufficient to let him know he has made an error.
Let me know if anything is unclear - and let me know how you get on.
Have fun
