"""The Wirehaired Fox Terrier is a bold and energetic Terrier. They are enthusiastically playful especially with children, but have been known to bite. They are affectionate with the family and do not hide their jealously. Cheerful and brave. They are ready to charge at all times. Scrappy and impulsive. This lovable dynamo is great at learning tricks. Amazing stories are told of the animal's loyalty and devotion. This dog enjoys being part of the family and will become destructive without enough exercise and attention. One of the most aggressive breeds, the Fox Terrier has a pronounced tendency to pick fights with other dogs, even large ones, and are not generally trustworthy with other pets. The Fox Terrier will also hunt and possibly kill other none K-9 animals, such as birds, if given the chance. Be careful, as the Fox Terrier has often bitten, and although they love to play, they should be watched with children. If the Fox Terrier is properly socialized and introduced they can get along just fine with other dogs in the family. Keep this breed properly leashed or in a completely enclosed area, because the Fox Terrier likes to go off and explore. Fox Terriers like to bark and make good watchdogs, although the high-pitched barking can be annoying and may cause problems with neighbors. They may be too boisterous for elderly owners. They are willful and need to be firmly obedience trained from an early age. Behavior problems may include dominance challenges, especially with meek owners; guarding objects, places and their own food from the owner, and excessive barking."""
