I think,though a toy breed, the Yorkie still retains much of its terrier ancestry in terms of personality.
Individual dogs sometimes differ, but they are
generally intelligent, independent and gutsy.
Yorkshire Terriers are quick to determine where
they fit in a household's "pack."Their behavior towards
outsiders will vary - they often will be inclined to bark
at strangers, but some Yorkies are outgoing and friendly
towards new people while others are withdrawn and aloof.
The differences in behavior in this regard are largely
based on how the owner trains or conditions (and socializes)
the Yorkie.A few individual Yorkshire Terriers
may be timid or nervous, rather than bold, but the
vast majority do seem to meet the breed standard for
a confident, vigorous and self-important personality.
