The Yorkshire Terrier is a small dog breed of terrier type, developed in the 19th century in the county of Yorkshire, England to catch rats in clothing mills, also used for rat-baiting. In the mid-19th century, workers from Scotland came to Yorkshire in search of work and brought with them several different varieties of small terriers. The Yorkshire Terrier was introduced in North America in 1872.
Though small, the Yorkshire Terrier is active, very overprotective, curious, and loves attention. Mentally sound and emotionally secure ones should normally not show the soft submissive temperament seen in lap dogs. Because of this, it is advised that a Yorkie would not be suitable for a home with typical young children—they are Terriers after all. Instead, they make ideal companions for older families. Yorkshire Terriers are an easy dog breed to train. Due to their small size, they require daily interaction with people. Yorkshire Terriers do tend to bark a lot. This makes them excellent watch dogs as they will sound the alarm when anyone gets close.
Average. Because they were developed as a working breed many need a lot of both physical and mental stimulation—with both relatively long walks/runs but also indoor games and training to keep their mind busy.
Between 18 to 21 cm / 3 kg.
