Welcome to YT! You will find that YorkieTalk has the answers to almost any question you can ask regarding your little Blake. And yes, many yorkie youngsters are quite a handful, but they DO grow up. They are extremely smart and most are very independent so that makes for training challenges.
Don't let their small size and beautiful coat fool you. They were originally bred for hunting small rodents - mice, rats, etc. It took courage, intelligence and independence to be successful at this task. The true terrier personality is one of the traits that endear us and frustrate us the most with our little Yorkshire Terrors (uuuhhh I mean terriers).
