Just as a matter of interest how many the dogs here come to a whistle ? I have always taught my dogs this from the moment they have come home . I never use the baby talk "come here come on " but rather a 4 fingered whistle in conjunction with a firm "come" and moving away from the dog . We were away over the weekend and my friends were amazed at karmas recall on a whistle from hundreds of metres away . As soon as she hears it she is inbound like an exocet missile !! I don't really think about it as I think all dogs should do it but do they ?
