The Yorkshire Terrier, often called a Yorkie, is a small dog breed known for its long, silky coat and lively personality. Weighing around 4 to 7 pounds, they are one of the smallest dog breeds. Originally bred in England for catching rats in clothing mills, they are now popular companion animals. Yorkies are intelligent and energetic, requiring regular exercise and mental stimulation. They are known for their loyalty and can be quite protective of their families. Their grooming needs are significant due to their long hair, making regular brushing essential to prevent tangles and mats.
