The personalities of the wire-haired fox terrier are lively, outgoing and sociable. This breed is not the type of dog that will blend quietly into the background, and is filled with vigor and the sheer joy of living. They make their presence very well known and are delightful companions. This breed has endless amounts of energy, therefore is best appreciated by the active person. Long and frequent walks are generally well appreciated by the fox terrier. Just when you think that they have had enough exercise, after a very quick nap they are ready for more activity.
This breed is a good child's dog, that never refuses an invitation to play. In fact, it is often the fox terrier that will initiate the suggestion to play. It is a common occurrence in our house, where Casey will bring us a favorite toy eagerly expecting someone to play with him. He will sit right in front of us patiently staring until the request is honored.
They are highly intelligent dogs. Very quick to learn and highly adaptive to new situations. We found Casey to be very eager to please us. When we would show our approval with a "good boy" and praise, he would be very pleased with himself. They are proud little dogs and it shows in that distinctive strutting gait. Anyone who lives with a terrier of any breeding they will probably tell you same thing. If you let them, they will run your life. The wire-haired fox terrier needs structure and rules. In a word "obedience" training.
The wire-haired fox terrier is a keen and vocal watchdog. They take this responsibility very seriously and will defend their home and family to all end. Though his appearance is not intimidating, I can tell you our letter carrier thinks his bark is that of a man-eater.
