The dog will either be afraid of you, or decide that obeying is optional.
If you know who owned the dog for you, try to talk with the former owner. Find out more about your new pet: what treats he prefers, how he spent time on walks. Conditions at the new place of residence of the dog should slightly resemble her former home – of course, if you have not taken an animal from the street, from a shelter or from people who treated him badly.

If the former owners raised her bad, spoiled, hard discipline she will likely not like it. Will require more time and effort to force the animal to obey and make it manageable. Try not to use force unless absolutely necessary.
The dog may have strong attachment to the former owner, even if he treated her badly. Therefore, until the animal gets used, do not leave him alone in the yard or on the street – the dog can escape. If the dog is sad, look depressed, do not take the time to communicate with her; if possible, print a play or for a walk.
