Jack Russell Terrier

History & Origin

The Jack Russell Terrier was developed in southern England in the early 19th century by Reverend John Russell. He wanted a terrier that could hunt foxes effectively-fast enough to keep up with hounds, small enough to follow quarry underground, and brave enough to face prey.

While similar breeds like the Parson Russell Terrier and Russell Terrier share ancestry, the Jack Russell Terrier became popular in its own right as a working terrier and companion. Though The Kennel Club does not formally recognise it as a pedigree breed, it is beloved worldwide.

What Were They Bred to Do?

Jack Russell Terriers were bred to hunt foxes and other small game. They excelled at flushing prey from burrows and working in the field with hunters. Today, their determination, agility, and keen instincts remain strong, making them excellent at canine sports such as agility, flyball, and earthdog trials.

Appearance & Breed Standard

Jack Russells are small, sturdy, and athletic. They have a compact body, strong legs, and an alert expression. Their tails are often carried upright, showing confidence.

Coats can be smooth, broken (a mix of smooth and rough), or rough, with all types being weather-resistant. White is the predominant colour, often with black or tan markings.

Temperament & Living with a Jack Russell Terrier

Jack Russells are bold, lively, and affectionate with their families. They are intelligent and full of energy, always ready for adventure. However, their strong prey drive and determination can make them challenging for first-time owners.

They are good with older children but may be too boisterous for toddlers. They thrive in active homes and can adapt to flat living if sufficiently exercised, but they are happiest with secure outdoor space.

Exercise & Mental Stimulation

Jack Russells need at least 1-1.5 hours of vigorous daily exercise. Long walks, off-lead running in secure areas, and interactive games are essential. They also benefit from activities like agility, obedience, and puzzle toys, which channel their intelligence and energy.

Without stimulation, they can become destructive or excessively vocal.

Training & Socialisation

Highly intelligent, Jack Russells learn quickly but can be stubborn and independent. Consistency, patience, and positive reinforcement are key. Early training is vital to prevent problem behaviours such as digging, barking, or chasing.

Socialisation from puppyhood helps them feel confident around people, dogs, and varied environments.

Grooming & Shedding

Jack Russells are low-maintenance dogs:

• Brush weekly (more often for rough or broken coats).

• Bathe occasionally.

• Check nails, ears, and teeth regularly.

They shed moderately year-round, more noticeably with smooth coats.

Health & Longevity 

Jack Russells typically live 12-15 years, with some reaching 16-17 years.

Health concerns may include:

• Patellar luxation

• Legg-Calvé-Perthes disease (hip condition)

• Deafness (especially in predominantly white dogs)

• Lens luxation and cataracts

• Skin allergies

They are generally a robust, hardy breed when responsibly bred.

Feeding & Care Basics

Jack Russells need a balanced, portion-controlled diet appropriate for small, active dogs. They can easily gain weight if overfed, so measured meals and healthy treats are recommended. Adults usually thrive on two meals per day.

Ethical Sourcing & Adoption 

Seek responsible breeders who health-test breeding dogs, particularly for eye and joint conditions. Many Jack Russells are available in rescues across the UK, as their lively nature sometimes proves too much for unprepared owners. Adoption is a great option for experienced homes.

Legal Note 

Jack Russell Terriers are not restricted under UK legislation.
