Most times when people visit the dog greets them. Usually with her hackles up and barking. We call out warnings "don't touch the dog" because she is truly not a friendly thing. She does not like strangers to touch her, she really hates when faces get near hers..all in all, she is a working farm dog and not an I love everything kind of dog.
Everyday she patrols the property. She searches constantly for creatures that do not belong, and when she locates them she quickly takes them out. She is constant, never tires of the search and is eager every day. The Jack Russel breed was bred to go, go, go..which can be why they can be difficult dogs to own. I have a book about Jacks..and the sub-title is "or demon dog". She is a working girl.
