The typical Keeshond has an outgoing personality. It is outwardly
affecti onate with its family and will accept strangers readily once
the owner has showed no concern for the strangers presence. The
Keeshond makes an excellent watch dog, that is, will bark a stern
warning any time a stranger approaches the household or one of its
members. The Keeshond rarely bites, however, and therefore does not
make a good guard dog. The Keeshond is a very trainable breed, but has
a mischievous streak that often results in embarrassment for the
owner. Some Kees have done very well in obedience competitions, but
most trainers will tell you about the "jokes" their dogs have pulled
on them in the ring.
Keeshonden are friendly by nature to both people and other dogs. Their
demand for affection is moderate to high. The pack-oriented nature of
the Keeshond means that they do better when included in the family
(pack, from their point of view) than when left outside by themselves.
As befits their Northern ancestry, they may enjoy spending periods
outside - particularly during cold weather - but their "place" should
be inside with the rest of the pack.
The Keeshond is known as the "Smiling Dutchman", which is often
displayed as a curled lip or submissive grin. Certain breeds have a
propensity for this behavior, the Keeshond is one of them. The grin is
a sign of submission and often used as a greeting for people the dog
is particularly fond of.
