Aggressiveness toward my cat.

[saschia]

Hi, I think maybe the problem is more deep. You say that Zaz is "not very good about listening to commands when he doesn't want to". That is the main problem. One year old vlcak should be able to comprehend that obeying is a must and should obey the "normal" commands in all but really complicated situations. At home, getting treats should now be only a really well-deserved reward. If he does not obey even if he is not distracted much, then the problem is in your authority. Even if the dog does not belong to you, if you live in the same household, it should consider you as an authority.
