Yea apparently it was not possible. I took him after 15 minutes he started to growl and he almost bite me and my sister. We instantly locked ourselvs in a room and called the owner. After they came in 2 minutes he slept near me. After that they took him. It was impossible i could not do anything. He literally start showing his teeth to me and after the onwer came he was so calm and all that stuff. Im so sorry for him and in my country is 9 PM we cant call any dog trainer nothing. He was so scared and we did not do anything to him..he searched the house did not find them and after that he start growl.
