DOGS BY BREED :: JACK RUSSELL TERRIER
Jack Russell Terrier
The Jack Russell Terrier originates from England and was bred originally for fox bolting and hunting - it was small enough to enter a fox-earth or drain, yet large enough to run with the hounds. Its origins can be dated back to the 1800's. The Jack Russell Terrier is also known by the other names of Jack Russell Terrier or the Parson Jack Russell Terrier. The name derives from the original owner and breeder the "Hunting Parson'" the Rev. John Russell ( The name John is often changed to Jack ). The English term Rev., or Reverend, was changed to its American counterpart of Parson by the AKC. This dog is classified as one of the Terrier Dog Group which we go on to describe in detail in the section at the bottom of this page. The Jack Russell Terrier was first Registered by the AKC (American Kennel Club) in 1998. Name Facts and Dog Names: This dog's name is sometimes misspelled as terrior and terriors.

The Jack Russell Terrier's coat is normally a shade of lemon, solid white or white with black and tan. The coat can be smooth or rough.
Character & Temperament
The Terrier dogs are small to medium size and are often described as fiery or feisty. The smallest terriers are ready to take on any opponents - a necessary attribute when hunting and killing vermin but not so good for a family pet! Some terriers are yappy and are known to nip boisterous children. They can also be quite independent and difficult to train. On the positive side Terriers can be friendly, stable and loyal pets.
Potential Health Problems
All owners of dogs and puppies are concerned about the health care of their pets and just as with humans dog health issues arise from time to time. Resolving dog health problems, including those of the Jack Russell Terrier, can prove to be costly and it would be wise to consider the benefits of obtaining dog health insurance. Diseases in dogs may occur because of trauma, infection, immune system abnormalities, genetic factors, or degenerative conditions. Common health problems and questions occur in relation to the Bones, Joints, Muscles, Nerves, Ears, Eyes, Teeth and the Mouth. Other, more serious, issues can relate to the Digestive System, Heart & Respiratory Systems, Immune & Blood Systems, Reproduction and Urinary Systems.

Age comparison between the Jack Russell Terrier Dog Breed and a Human
Age comparisons between dogs and humans are always a matter of debate - we hope that the following information clarifies the situation. After the first year of life, a dog is equivalent to sixteen human years. After two years, they are equivalent to a 24 year old, at three years a 30 year old, and each year after, add 5 human years to determine a dog's age.
Terrier Dog Breed Information
Dogs in the Terrier group, which include the Jack Russell Terrier, were developed to hunt and kill vermin. The vermin included control rats, mice and other predatory animals such as foxes that might raided a farmer's produce and livestock. The very nature of these tasks require an energetic, tenacious, brave and determined dog such as the Jack Russell Terrier . Terrier dogs have always been viewed as real assets by their owners and have worked with man for centuries.
Terrier Dog Breed Duties and Tasks
Characteristics and features of Terrier Dogs have been introduced and strengthened by breeding with animals who already demonstrated the desired traits. Breeding for appearance was only introduced in the 19th Century. Before this time dogs and puppies were bred to increase useful abilities and traits helpful for the duties they were intended for. The trait encouraged was the ability to dig up underground dens and burrows and "go to ground" whilst barking noisily to frighten out any inhabitants. Thus, the various Terrier breeds, including the Jack Russell Terrier, were introduced to help man according to his specific requirements such as:
- Hunting vermin
- Hunting larger animals such as foxes
- Some terriers were also able to kill their quarry
