Due to their working nature, Jack Russell terriers remain much as they were some 200 years ago. They are sturdy, tough, and tenacious, measuring between 10–15 inches (25–38 cm) at the withers, and weigh 14–18 pounds (6.4–8.2 kg). The body length must be in proportion to the height, and the dog should present a compact, balanced image. Predominantly white in coloration (more than 51%) with black and/or tan markings, they exhibit either a smooth, rough or a combination of both which is known as a broken coat.
The small white-fox working terriers we know today were first bred by the Reverend John Russell, a parson and hunting enthusiast born in 1795, and they can trace their origin to the now extinct English White terrier. By the 1850s, these dogs were recognised as a distinct breed.
The Jack Russell Terrier is a cheerful, merry, devoted and loving dog. 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
Having a Jack Russell dog can be a wonderfully rewarding experience. They are incredibly loyal, energetic and affectionate, and they make great companions. However, they require plenty of attention and exercise, and they can be quite stubborn at times. The best advice for having a Jack Russell is to be consistent with training and discipline. These dogs are smart and energetic, so they need plenty of mental and physical stimulation. Regular walks and playtime are essential, and they should be taught basic commands and house rules from an early age. It's also important to stay on top of their health. Jack Russells can be prone to certain health problems, so regular vet visits are a must. Additionally, they need to be groomed regularly to keep their coat in good condition. In short, Jack Russells are wonderful pets if you're willing to put in the effort. With consistent training and plenty of attention, you can have a loyal and loving companion for many years to come.
