I have a now 13 week old Australian Shepard. He is such a good boy, he is house trained already, crate trained, knows sit, down, shake and come...he is really a great dog! Now....the problem is that he is VERY afraid of people..but not everyone. I am totally stumped with what to do and everyone that I talk to and everything I read tells me something different. I am very confused and so afraid that he will turn mean We love him dearly and hope that we can do something to help him before it's too late. Please help!!!
