Used in the early 19th century by herds of dogs and the Reverend John Russell, the Jack Russell Terrier has its origins in modern Fox terriers and is generally parson Russell Terrier The American Kennel Club (AKC) and affiliate variant) and Russell Terrier. Although considered by many to be similar to or different from the Paras Russell Terrier, Jack Russell fans consider it a unique work terrier breed, while the Parson Russell is a breeding breed. Jack Russell is a widespread type and the name is often mistaken for any small white-haired terrier breed. The typical “Jack Russell Terrier” should be within the size range of 10–15 , the Parson Russell is typically the bottom size with a standard size of 12–14 , while the Russell Terrier is the smallest at 8–12 . However, each breed has different physical proportions according to the standards of its breed clubs.

Jack Russell Terrier Dog Breed


The Jack Russell Terrier and the Parson Russell Terrier are considered to be one in many of the same breed, saving different breed standards. From 1997–2003, those members of the breed between 13–14 were recognized as Jack Russell Terriers by the American Kennel Club (AKC). The 14- standard was used by the AKC by the Russell Russell Terrier Association of America (JRTAA). Founded in 1985, JRTAA was also the official breed parent club within the AKC at the time. However, the Jack Russell Terrier Club of America (JRTCA), established in 1976, felt that the standard two were restrictive and required a height of 10–15 instead. By 2003, the fighting and estrangement between the radicals on both sides led the AKC to change the name of the Paras Russell Terrier. The dogs were first registered as Jack Russell Terriers and then became known as Parson Russell Terriers. The JRTAA also changed its name to the Paras Russell Terrier Association of America (PRTAA) and remained the official official Diamond Club.

It did not accept the name Ter Jack Russell Terrier within AKC but went away. JRTCA remained active and firm in its opinion that the “”Real Jack Russell Terrier”” could be any height between 10 “”and 15″” and that there was no “”ideal”” shape; As the owner is the ideal size to do the work that is needed today, JRTCA calls itself “”the National Breed Club and Registry for Jack Russell Terrier in the United States and the largest Jack Russell Terrier Club and Registry in the world”” Tells. “”

There remains considerable disagreement among breeders, fanatics, kennel clubs, and experts on how to treat the difference between the Jack Russell Terrier and the Parson Russell Terrier. The most common treatment is the Paras Russell Terrier considered as the distortion show variety of the Jack Russell Terrier breed. It is a treatment shared by almost every major national and international kennel club, including AKC. The UKC further confuses the issue by calling its dogs the Parson Russell Terrier, but use the broader Jack Russell Terrier standard. In short, the UKC is saying that the two breeds are the same, and the official breed name is the Parson Russell Terrier.

However, many organizations take different stances. Many members of the PRTAA believe that the Jack Russell Terrier is not a breed, but rather a common type of dog that is similar to a retriever or spaniel. Similarly, while most JRTCA members consider the Parson Russell Terrier to be a variant of the Jack Russell Terrier, others argue that since the breed does not require the ability to register, these dogs are not Jack Russell Terriers. The Australian National Kennel Council (ANKC) and the New Zealand Kennel Club (NZK) are the only two major canine bodies that consider the Jack Russell Terrier and the Parson Russell Terrier as two unique breeds and register them as such.

General Appearance

Thanks to the breeds numerous appearances on film and television, the Jack Russell Terrier is one of the most recognizable dog breeds in the world. The Jack Russell Terrier closely resembles the original working style of the Fox Terrier, which is actually the Jack Russell Terrier.

It is a small terrier breed, and the length of the breed members should be between 10 and 15.

The specific weight range for the Jack Russell Terrier is 14 to 18 pounds, although Working Dogs may weigh slightly less. As with all dog breeds, male Jack Russell terriers are slightly larger than females, although this breed exhibits the lowest sexual dimorphism.

Jack Russell has a head and a muzzle that are well proportioned with the dog’s body shape. The muzzle should be slightly less than the length of the head.

Both Wishbone and Jim Carrey’s dog in The Mask were played by the smooth-coated Jack Russell Terriers. The Rough Coated Jack Russell Terrier has a traditional breed terrier coat, which is found on breeds such as the Cairn Terrier or The Wire Fox Terrier. Eddie from Frazier was played by a thick-coat Jack Russell terrier. Broken-coated Jack Russell Terriers have a coat that is smooth and rough. These dogs often have long hair on their faces, giving them the impression of having a beard or goatee. Neither the rough nor the torn coat Russell Russells should have a woolen coat.
