I recently adopted a 3 year old rescued male chihuahua. He bonded to me almost immediately and follows me everywhere. He is the sweetest little guy but because of his history (he was abused and then lived as a stray) he was terrified of people other than me and would bark and growl when anyone came near him. The only people he didn't have a problem with were kids. Recently thous he appears to have come out of his shell and get all excited, tail wagging when my boyfriend comes over. I'm especially thrilled because he seemed extra scared of men. He let the bf take him for a walk and even jumped up on h and gave him kisses! Does this mean he will become comfortable with others?
