The Jack Russell Terrier
The Jack Russell Terrier is a small terrier that has its origins in fox hunting in England. It is principally white-bodied and smooth, rough or broken-coated and can be any colour.
Jack Russells are an energetic breed that rely on a high level of exercise and stimulation. They are relatively free from any serious health complaints. Originating from dogs bred and used by the Reverend John Russell in the early 19th century, from whom the breed takes its name, the Jack Russell has similar origins to the modern Fox Terrier.
Jack Russells are first and foremost a working terrier, originally bred to bolt foxes from their dens during hunts. Jack Russells tend to be extremely intelligent, athletic, fearless, and vocal dogs. It is not uncommon for these dogs to become moody or destructive if not properly stimulated and exercised, as they have a tendency to bore easily and will often create their own fun when left alone to entertain themselves.
Their high energy and drive make these dogs ideally suited to a number of different dog sports such as flyball or agility. Obedience classes are also recommended to potential owners, as Jack Russells can be stubborn at times and aggressive towards other animals and humans if not properly socialized. Despite their small size, these dogs are not recommended for the condominium or apartment dweller unless the owner is ready to take on the daunting task of providing the dog with the necessary amount of exercise and stimulation. They have a tremendous amount of energy for their size, a fact which can sometimes lead to trouble involving larger animals. They may seem never to tire and will still be energetic after their owner has called it a day. While socialised members of the breed are friendly towards children, they will not tolerate abuse even if it is unintentional.
The breed has a reputation for being healthy with a long lifespan
