Yorkshire Terriers are incredibly smart, alert, and easy to train dogs. According to some recent research, out of 90 breeds, Yorkshire Terriers stood at the 27th position, securing a position above average intelligence. This implies that Yorkies can learn a new command only after 15 to 25 repetitions, and once a Yorkie understands and memorizes the command, it will obey it almost 70% of the time. Besides, they have a smart personality, are quite instinctive, and can adapt to different situations.
