Appenzells are loyal, affectionate, brave, intelligent and energetic. These dogs will usually form a strong bond with one owner but will be loyal and respectful to all family members as long as proper training has taken place and the dog understands that it is lower in the pack hierarchy than humans. The Appenzell is used to working around animals and gets along well with other dogs, livestock, and household animals if it has been socialized while still young. These dogs have been watchdogs for centuries and may be apprehensive towards strangers, though they should not be aggressive. Barking should be expected, and socialization should be done to minimize this behavior.
Dogs of this breed respond well to firm, calm training. They learn quickly, partly because they are quite smart, but also because they greatly desire to have a job or activity to perform. They enjoy the outdoors and thrive in a location that gives them a lot of open space to run around and play. It is imperative that this dog's owners be higher up on the pack hierarchy. Otherwise the dog may be hard to control and somewhat unruly. It is also very important to exercise this dog and stimulate it mentally and physically, especially if it is not employed as a work dog. Therefore it should be apparent that these dogs are not good for lazy or very busy owners, especially in an urban location.
