Commonly referred to as the “Yorkie”, the Yorkshire Terrier is a small dog with plenty of spark and personality. One of the most popular dog breeds in the United States, the Yorkie has a long silky coat that is steel-blue and tan in color. Used primarily as a companion dog, the Yorkshire Terrier is self-assured and fearless, while being very affectionate toward its owner. It needs lots of attention, and if left alone for long periods of time, it may develop separation anxiety. Due to its small size and occasional skittishness, the Yorkie functions better with older children that have learned how to treat animals.
