Hybrid Description

The Jug is not a purebred dog. It is a cross between the Jack Russell Terrier and the Pug. The best way to determine the temperment of a mixed breed is to look up all breeds in the cross. It is possible you can get any combination of any of the characteristics found in either breed. Not all of these designer hybrid dogs being bred are 50% purebred to 50% purebred. It is very common for breeders to breed multi-generational crosses. Please review individual breeds for potential health issues.


Jack Russell Terrier Breed Description - Cross #1

The JRTCA was founded in 1976 by Mrs. Ailsa Crawford, one of the first Jack Russell Terrier breeders in the United States. Ms. Crawford and the early founders of the Jack Russell Terrier Club put a lot of thought into structuring the JRTCA so that work remained front and center.

Towards that end, the club decided that its highest award — the “Bronze Medallion” — would not go to show dogs, but to working dogs that had demonstrated their ability in the field by working at least three of six types of American quarry — red fox, Gray fox, raccoon, groundhog, opossum, or badger in front of a JRTCA-certified field judge. In the show ring the Jack Russell Terrier Club of America decided to ban professional handlers as it was thought this would make the shows less serious (and more fun) while keeping the focus on the essential element of work.

Instead of mandating the kind of narrow conformation ranges demanded by the American Kennel Club for their terrier breeds, the JRTCA decided to divide the diverse world of the Jack Russell Terrier into three coat types (smooth, broken and rough), and two sizes (10 inches tall to 12.5 inches tall, and 12.5 inches tall to 15 inches tall).“Different horses for different courses” became the watchword, with overt recognition that different quarry, different earths, and different climates required different dogs.

Unlike the Kennel Club, the Jack Russell Terrier Club of America also decided to maintain an “open” registry so that new blood might be infused at times. At the same time, the JRTCA discouraged inbreeding and eventually restricted line breeding to a set percentage. To balance off an open-registry with the desire to keep Jack Russell-type dogs looking like Jack Russells, the JRTCA decided not to allow dogs to be registered at birth or to register entire litters. Instead, each adult dog would be photographed from both sides and the front, with each dog admitted to the registry on its own merit. In addition, each dog had to be measured for height and chest span. This last element turned out to be quite important, as it meant that the height and chest measurements of adult dogs were recorded as they were registered. Over time, both height and chest size of adult dogs could be tracked through pedigrees — an essential element of breeding correctly sized working terriers. The JRTCA was not shy about their rationale for these rules: they openly and emphatically opposed Kennel Club registration, maintaining that time had shown that dogs brought into the Kennel Club quickly grew too big and often lost other essential working attributes such as nose, voice, and prey drive.

The Jack Russell Terrier is bred to conform to a conformation show standard. Unlike its close relative, the Parson Russell Terrier, Jack Russell Terriers have noticeably longer legs that are about as tall as the length of the Terrier's body. It is a predominantly white breed with black, tan or tricolor markings and an easy to groom coat which is either smooth or broken (similar to a smooth coat, but with some longer hair on the head, face, legs or body). The breed standard does not recognise a Parson Russell with a curly or rough coat. There is a clear outline with only a hint of eyebrows and beard should the dog be broken coated. They possess moderately thick small "V" shaped drop ears with the tip pointed towards the eyes. The nose of the dog should be black. The normal range of sizes is between 13–14 inches (33–36 cm) tall at the withers, with a weight around 13–17 pounds (5.9–7.7 kg).

The Parson Russell has a relatively square outline, with a body about as long as the dog is tall. Compared to the Jack Russell Terrier the Parson Russell has a longer head and a larger chest along with overall a slightly larger body size. The Parson retains the flat skull but not the elongated shape of the Fox Terrier, and with lower set ears. In addition, the Jack Russell Terrier has a greater variation in size, ranging between 10–15 inches (25–38 cm) in height at the withers. Two hands should be able to span the chest of the dog behind its elbows, with the thumbs at the withers. This is required in show judging, with the judge lifting the dog's front legs gently off the ground in this motion in order to measure the size of the chest. The judges fingers should meet under the chest and the thumbs on top of the spine. The American Kennel Club describes this as a "significant factor and a critical part of the judging process." It is not done to measure the size of the chest, but rather to feel for the correct shape.

Under the show standard, there are several physical points which would be treated as faults in the show ring. These are for the height of the dog at the withers to be outside of the standard range, or for the dog to possess either pricked up ears, a liver or brown colored nose, an overshot or undershot jawline or to have brindle markings.

The AKC used to recognize the Jack Russell Terrier however as of April 1, 2003 they changed the name to Parson Russell Terrier. The breed split into two breeds and now the Jack Russell Terrier and Parson Russell Terrier are considered two different breeds. The Parson's name change is in great part to a lawsuit from the JRTCA to the AKC, when the breed was first allowed registration.

Behavior

The Terrier is a cheerful, merry, devoted and loving dog. It is spirited and obedient, yet absolutely fearless. Careful and amusing, he enjoys games and playing with toys. Stable dogs are friendly and generally kind to children. Children should be taught not to tease or hit the dog. They are intelligent, independent, somewhat stubborn, and they have a strong personality. He makes a devoted, affectionate pet and is easy to train.

He can adjust to life as a house dog provided he gets a lot of much needed exercise. The coat requires little care.

Health

The breed is sporadically prone to dislocation of the kneecaps, inherited eye diseases, deafness and Legg Perthes, a disease of the hip joints of small dog breeds. It is also prone to mast cell tumors.




Pug Breed Description - Cross #2

The pug is a toy dog with a wrinkly, short-muzzled face and curled tail. The breed has a fine, glossy coat that comes in a variety of colors, although often black or fawn, and a compact square body with well-developed muscles. Known in ancient China as lo-sze, pugs as breeding animals may have contributed to the English Bulldog, the modern Pekingese and the King Charles Spaniel. Pugs were brought from China to Europe in the seventeenth century and were popularized in Western Europe. Pugs remain popular into the twenty-first century, with some famous celebrity owners. A pug was judged Best in Show at the World Dog Show in 2004.

Pugs have two distinct shapes for their ears, "rose" and "button". "Rose" ears are smaller than the standard style of "button" ears, and are folded with the front edge against the side of the head. Breeding preference goes to "button" style ears.

Pugs' legs are strong, straight, of moderate length and are set well under. Their shoulders are moderately laid back. Their ankles are strong, their feet are small, their toes are well split-up, and their nails are black. The lower teeth normally protrude further than their upper, resulting in an under-bite.

Behavior

Affectionate, intelligent, and gentle, this little lap dog is a good-natured pet but can be exclusive and touchy. The rambunctious Pug puppy becomes a calm, poised adult. He seldom barks and is not a watchdog, despite being reserved toward strangers. He needs firm, very early training.

This breed is often described by the Latin phrase multum in parvo, or "much in little" or "a lot of dog in a small space", alluding to the pug's remarkable and charming personality, despite its small size. Pugs are strong willed but rarely aggressive, and are suitable for families with children. The majority of the breed is very fond of children and sturdy enough to properly play with them. Depending on their owner's mood, they can be quiet and docile but also vivacious and teasing. Pugs tend to be intuitive and sensitive to the moods of their owners and are usually eager to please them. Pugs are playful and thrive on human companionship. They also tend to have a snoozy nature and spend a lot of time napping. Pugs are often called "shadows" because they follow their owners around and like to stay close to the action, craving attention and affection from their owners.

He is perfectly suited to apartment life. Not being very athletic, short walks suffice. He hates being left alone or separated from his owner. He should be kept out of intense heat since, like all brachycephalic dogs, he is susceptible to respiratory blockage. His eyes are sensitive to dust and need regular checking, as do the wrinkles on his face. He must be brushed twice or three times a week.

Health

Pugs are prone to brachycephalic airway obstructive syndrome (BAOS) which causes respiratory distress in short-snouted breeds. Pugs have elongated palates. When excited, they are prone to "reverse sneezing" which causes them to quickly (and seemingly laboriously) gasp and snort. The veterinary name for this is pharyngeal gag reflex and it is caused by fluid or debris getting caught under the palate and irritating the throat or limiting breathing. Reverse sneezing episodes are usually not harmful, and massaging the dog's throat or covering its nose in order to make it breathe through its mouth can often shorten a sneezing fit.

Some pugs are also born with stenotic nares (pinched nostrils) which can inhibit their breathing. In serious cases, it makes breathing even more difficult and puts added pressure on the larynx. In some cases, the dog could pass out from blocked airways. If this happens, one should inquire with their veterinarian whether or not surgery is needed to open the nostrils.

Protruding eyes and eye prolapse is a common problem among pugs and other brachycephalic breeds and can be caused by a trauma to the head or neck. While the eye can usually be pushed back into its socket by the owner or by a vet, veterinary attention is usually advisable. If the prolapse happens on a regular basis, the pug might require surgery.

Pugs have many wrinkles in their faces, so owners will often clean inside the creases to avoid irritation and infection. If this is not done, the dog may develop a condition known as skin fold dermatitis.

An abnormal formation of the hip socket, known as hip dysplasia, affected nearly 64% of pugs in a 2010 survey performed by the Orthopedic Foundation for Animals; the breed was ranked the second worst-affected by this condition out of 157 breeds tested.

Pugs are one of several breeds that are more susceptible than other dogs to demodectic mange, also known as "demodex". This condition is caused when parasitic mites, that are often present in a dog's skin without causing symptoms, are allowed to do damage because their host has a weakened immune system. It is a problem for many young pugs, although not usually a major one, and is easily treatable, but some are especially susceptible and present with a systemic form of the condition. This vulnerability is thought to be genetic and breeders will avoid producing puppies from adults who have this condition.

In 2008, an investigative documentary carried out by the BBC found significant inbreeding between pedigree dogs, with a study by Imperial College, London, showing that the 10,000 pugs in the UK were so inbred that their gene pool was the equivalent of only 50 individuals.

Pugs can suffer from necrotizing meningoencephalitis (NME), also known as pug dog encephalitis (PDE), an inflammation of the brain and meninges. NME also occurs in other small dogs, such as the Yorkshire Terrier, Maltese, and Chihuahua. There is no known cure for NME, which is believed to be an inherited disease. Dogs usually die or have to be put to sleep within a few months of onset, which, in those susceptible to this condition, is mostly between six months and three years of age.

This breed, along with other brachycephalic dogs (e.g., boxers, bulldogs), are also prone to hemivertebrae. The curled tail of a British bulldog is an example of a hemivertebrae, but when it occurs not in the coccygeal vertebrae but in other areas of the spine, it can cause paralysis. The condition occurs when two parts of a spinal vertebra do not fuse properly while a young pug is still growing, resulting in an irregularly shaped spinal cavity which can put pressure on the spinal cord.
