Napoleon is quite the character, as his name suggests. He came to us as a pretty fearful, aggressive pup, but with lots of work from his foster he is learning to trust humans and is getting a little overly confident now. He is learning that he is not in charge and he needs a human who will not bow down to his every whim and mood swing. His foster says, "Show no fear and he will love you!" As long as you aren't hesitant with him he does great and will let you do pretty much anything to him. But if someone is shy and hesitant around him he goes on a little tirade and can get growly and nippy . If you are an experienced, confident human who would love a little buddy, then Napoleon is for you!
