terrier type, and of any dog breed. Yorkie's, like many other Toy breeds, make good pets for people;
they're especially good for senior citizens, people with medical
issues, and those who may worry about the size and strength of a larger
dog. ... They're loving, devoted, and very affectionate: This makes them
great personal companions and good family pets.Canine Intelligence – Where Does the Yorkshire Terrier Stand?
