I am new to the forum and have a 7 month male yorkie. He is wild!!! I can barely control him. I got him to finally learn how to sit and lay down now we r working on stay. He bites me all the time especially when trying to brush him or put his leash on. He also likes to dart out my front door which scares me because he could run right in front of a car. He jumps on me and tears my any clothing i have on. I am considering an obedience class but i have heard that they dont do well because they r so stubborn. Please i need advice or i am gonna go crazy .
