First you decide what 'code' you're going to use - it's entirely up to you. For a recall I use four short 'pips', and I train this by blowing the 4 pips every time I give the dog his dinner. Once he's associated it with food, I start giving the signal when I'm in the garden with him, when I want to give a treat - blow the 4 pips, and call him over, then reward with the treat and give loads of praise. I find it best if the whistle
always means a terrific reward, and
never anything unpleasant.
