Yorkshire Terriers are very playful and energetic dogs. Many people who have a Yorkie as a pet have two, because they often have separation anxiety when left alone and 'they don’t enjoy being alone.' . Owners may trim the hair short for easier care. The oil has to be washed out once a month and the wraps must be fixed periodically during the week to prevent them from sliding down and breaking the hair. Elaborate coat care dates from the earliest days of the breed. In 1878, John Walsh described similar preparations: the coat is 'well greased' with coconut oil, the dog is bathed weekly, and the dog's feet are 'carefully kept in stockings'.
