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 Color.
The Jack Russell is frequently confused with the Parson Russell Terrier (see the American Kennel Club) and the Russell Terrier, which is a shorter-legged, stockier variety (within the Fédération Cynologique Internationale, the "Russell terrier" is also known as the "Jack Russell terrier"). The term "Jack Russell" is also commonly misapplied to other small tan and white terriers. The Jack Russell is a broad type, with a size range of 25–38 cm (10–15 in). The Parson Russell is limited only to a middle range with a standard size of 30–36 cm (12–14 in), while the Russell terrier is smaller at 20–30 cm (8–12 in). Each breed has different physical proportions according to the standards of their national breed clubs.
Jack Russells are an energetic breed that relies 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. It has gone through several changes over the years, corresponding to different use and breed standards set by kennel clubs. Recognition by kennel clubs for the Jack Russell breed has been opposed by the breed's parent societies – which resulted in the breeding and recognition of the Parson Russell terrier. Jack Russells have appeared many times in film, television, and print – with several historical dogs of note.
The Jack Russell terrier is a happy, energetic dog with a strong desire to work. This breed is most happy when given companionship and a job to do. Digging is normal for a Jack Russell, especially if he decides it is his job to free your yard from rodents! Hunting ability is bred into them; it is their nature. The desire to hunt combined with a high energy level makes training a must for Jack Russell. You will never win a battle of wills with a Jack Russell.
Because he is a baying terrier, Jack Russell can be vocal. However, these dogs are alert and make good watchdogs. The breed is naturally assertive and may not tolerate young children or other animals in the home. They especially can be aggressive toward other dogs.
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 socialized members of the breed are friendly towards children, they will not tolerate abuse even if it is unintentional.
