As the Jack Russell Terrier evolved beyond its strictly working roots, two distinct types began to emerge. This eventually led to a split and the official recognition of the Parson Russell Terrier as a separate breed by kennel clubs like the American Kennel Club (AKC). So, what exactly are the key differences between these two terriers, and why did this division occur?
Size and Proportions: This is the most noticeable difference.
Parson Russell Terrier: Generally taller and more square in proportion. The ideal height is 13-15 inches at the withers (the highest point of the shoulders). Their body length is roughly equal to their height.
Jack Russell Terrier: Generally shorter and more rectangular in proportion. They tend to be between 10-12 inches tall, and their body is noticeably longer than their height.
Leg Length: Directly related to the overall size difference.
Parson Russell Terrier: Longer legs, giving them a more athletic and "leggy" appearance.
Jack Russell Terrier: Shorter legs, giving them a lower-to-the-ground appearance.
Body Shape:
Parson Russell Terrier: More square, as mentioned above. Their chest is moderately deep.
Jack Russell Terrier: More rectangular, with a longer back in relation to their leg length.
Breed Standards:
Parson Russell Terrier: Has a clearly defined and strictly enforced breed standard by organizations like the AKC. This standard dictates everything from size and proportions to coat type and temperament.
Jack Russell Terrier: While some Jack Russell Terrier clubs exist, they often prioritize working ability over strict adherence to a physical standard. There's more variation within the Jack Russell Terrier type.
Temperament (Subtle Differences):
Parson Russell Terrier: While still energetic and intelligent, some breeders and owners suggest that the Parson Russell Terrier, due to selective breeding for show, might be slightly more amenable to training and slightly less independent than some Jack Russells. However, both breeds are still very much terriers!
Jack Russell Terrier: Known for their intense prey drive, boundless energy, and independent spirit. They require experienced owners who can provide consistent training and plenty of exercise.
Why the Split? A Matter of Ideals
The decision to recognize the Parson Russell Terrier as a separate breed was driven by a desire to standardize the breed and make it more suitable for conformation shows (dog shows where dogs are judged on how well they conform to the breed standard).
However, many Jack Russell Terrier enthusiasts strongly opposed this move. They argued that:
Standardization Would Ruin the Breed: They feared that focusing on appearance would compromise the working ability and genetic diversity that made the Jack Russell Terrier so special.
Working Ability Should Be Paramount: They believed that the Jack Russell Terrier should be judged on its ability to perform its original function (fox hunting) rather than its looks.
"Type" is More Important Than "Breed": They felt that maintaining the type of dog that Parson Russell originally bred was more important than adhering to a rigid breed standard.
This disagreement led to a division within the Jack Russell Terrier community, with some breeders choosing to focus on the Parson Russell Terrier and others continuing to breed Jack Russells according to their own ideals.
Which One is Right for You?
Ultimately, the choice between a Jack Russell Terrier and a Parson Russell Terrier depends on your individual preferences and lifestyle.
If you're looking for a dog that conforms to a specific breed standard and you're interested in showing your dog, the Parson Russell Terrier might be a good choice.
If you're looking for a working terrier with a strong prey drive and you're willing to embrace the challenges that come with owning a highly energetic and independent breed, the Jack Russell Terrier might be a better fit.
No matter which type you choose, be prepared to provide your terrier with plenty of exercise, mental stimulation, and consistent training. These dogs are not for the faint of heart, but they can be incredibly rewarding companions for the right owners.
Delving Deeper: The Ancestry of the Jack Russell Terrier.
While Trump is considered the foundational bitch of the Jack Russell Terrier, she wasn't created in a vacuum. Parson Russell likely used a variety of terrier types common in England during the early 19th century to develop his ideal hunting companion. Pinpointing the exact breeds used is difficult, as records from that time are often scarce and imprecise, but we can make some educated guesses based on the characteristics of early Jack Russells and the types of terriers that were prevalent in the region.
Likely Ancestors and Influences:
The Fox Terrier (Smooth and Wirehaired): This is perhaps the most significant influence. Fox Terriers were already well-established as hunting dogs in England, known for their courage, tenacity, and ability to bolt foxes. Parson Russell likely used Fox Terriers to add these qualities to his own line of terriers. The predominantly white coat color, common in Jack Russells, is also a trait inherited from the Fox Terrier, helping hunters distinguish them from the fox.
The Old English White Terrier (Now Extinct): This breed, also known as the English Terrier, was a popular working terrier in the 18th and 19th centuries. They were known for their predominantly white coat, compact size, and courage. It's highly likely that Parson Russell used Old English White Terriers in his breeding program to refine the size and tenacity of his terriers.
The Beagle: While primarily used for hunting hare, Beagles were sometimes crossed with terriers to improve their hunting ability. It's possible that a small amount of Beagle blood was introduced into the early Jack Russell lines, contributing to their scenting ability and stamina.
Other Local Terrier Types: England in the 19th century was home to a variety of regional terrier types, each adapted to the specific hunting needs of their local area. These terriers would have varied in size, coat type, and temperament. It's likely that Parson Russell incorporated some of these local terriers into his breeding program to add specific traits or to improve the overall health and vigor of his line.
From Fox Hunts to Family Fun: A Look at the Jack Russell Terrier's History.
The Jack Russell Terrier: a small dog with a huge personality. These energetic, intelligent, and often mischievous pups are beloved by many, but how much do you really know about where they came from? Buckle up, because the history of the Jack Russell is a fascinating journey through the English countryside, filled with fox hunts, dedicated breeders, and a whole lot of terrier tenacity.
The Parson and His Passion:
Our story begins in 19th-century England with a parson named... you guessed it... John (nicknamed "Jack") Russell. Born in 1795, Parson Russell wasn't just devoted to his parish; he was also passionate about fox hunting. He believed that a good hunt required a specific type of dog: a small, brave terrier with the stamina to keep up with the hounds and the courage to bolt foxes from their dens.
In 1819, while studying at Oxford, Russell acquired a dog named Trump. Trump, a predominantly white terrier with dark tan markings, is considered the foundation bitch of the Jack Russell Terrier breed. (Think of her as the terrier equivalent of "Eve"!) Russell meticulously bred Trump and her offspring, focusing on working ability and temperament rather than appearance. He wanted a dog that could do the job, looks were secondary.
The Ideal Hunting Companion:
Parson Russell's terriers were bred for a specific purpose: to "go to ground" and flush out foxes so the hunt could continue. They needed to be small enough to enter fox dens, brave enough to face a potentially angry fox, and have a distinctive bark (so the hunters knew where they were underground). Importantly, they also needed to be friendly to the larger hounds, to prevent fighting during the hunt.
These early Jack Russells weren't a standardized breed. Parson Russell focused on function over form, so there was considerable variation in size, coat type, and leg length. Some were smooth-coated, others rough-coated, and some had broken coats. What they all had in common was their hunting ability and their spirited personalities.
Breeding for a Purpose, Not a Pedigree
It's important to remember that Parson Russell's primary goal wasn't to create a new breed in the modern sense of the word. He was focused on creating a type of dog that excelled at a specific task: bolting foxes. He was less concerned with maintaining a consistent appearance and more concerned with selecting dogs that possessed the necessary traits for the job. This is why the early Jack Russells were so diverse in appearance.
Parson Russell was an avid hunter who needed a dog to fit a very specific need. He likely crossbred different types of terriers to achieve his goal.
