By using this analogy, we are able to help owners realise why their dog is behaving as it is, for example pulling on the lead, despite the halti, harness, check chain put on it, they will literally work through the pain because the job of leader is more important than the pain. It's so important, therefore, to relieve the dog of it's leadership position, then it can relax and look to you for help.
Take a look at this enchanting story of a mother doing just that.
Clinging for dear life to the side of a vertical cliff, the tiny lion cub cries out pitifully for help.
His mother arrives at the edge of the precipice with three other lionesses and a male. The females start to clamber down together but turn back daunted by the shear drop. Eventually one single factor determine which of them will risk her life to save the youngster - Motherly Love.
The drama begins: The mother arrives at the edge of the cliff as her son cries out for rescue after being trapped when he slipped.
On the brink: Four lionesses look over the edge before aborting their rescue mission because of the sheer drop.
Slowly, agonisingly, the big cat edges her way down towards her terrified son, using her powerful claws to grip the crumbling cliff side.
One slip from her and both animals could end up dead at the bottom of the ravine.
Just as the exhausted cub seems about to fall, his mother circles beneath him and he is snatched up in her jaws.
She then begins the equally perilous journey back to the top.
Minutes later, they arrive and she gives the frightened creature a consoling lick on the head.
The dramatic rescue, captured by wildlife photographer Jean-Francois Largot, was played out in Kenya's Massai Mara game reserve.
