How does your dog feel like when you fasten a lead? This question may 
sound odd for a good many of people. However the dog`s feeling during a 
lead fastening will weigh in how easily you will fasten a lead next 
time. So that the dog leash fastening did not become an unpleasant 
procedure and the dog wouldn`t avoid it, it is important to consider the
 signals of dog reconciliation. Stand alongside of your dog, be quiet 
and relaxed. Fasten a dog lead with a subtle motion of the hand without 
touching a dog. If to press on its back, pull to yourself and make 
noise, the dog will start avoiding the lead fastening. And if your dog 
lies down and shows a signal of reconciliation when you try to fasten a 
dog leash, it means, that it`s afraid and you do someting wrong.
