I have been following a Canadian show on TV called At The End Of My Leash, in which Brad Pattison becomes the Bratty-Dog Whisperer. He uses the ubilical leash technique anyone tired it here? Although you can make your own umbilical leash, I will buy a ready one since I saw at the pet shop near me they sell it, and I can have 2 dogs on it at the same time. Although I will be using normal obedience techniques for most of the stuff, and I will start going through the sessions here on this forum, I was thinking of the umbilical mainly because my girl has a bad habit, that the minute I open the door, she runs out so fast that it is hard to catch her. I am lucky so far that she is not running towards the street, but towards the neighbour to visit her new found Golden regriever. If you have had sucess with this technique, how many hours a day did you do it? Brad normally recommends between 2-3 hours a day, but that might be a little too long ?
