Hybrid Description

The China Jack is not a purebred dog. It is a cross between the Chinese Crested Dog and the Jack Russell Terrier. 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.

Chinese Crested Dog Breed Description - Cross #1

The Hairless and Powderpuff varieties of Chinese Crested Dogs appear to be two different breeds, but hairlessness is an incomplete dominant trait within a single breed. The Hairless has soft, humanlike skin, as well as tufts of hair on its paws ("socks") and tail ("plume") and long, flowing hair on its head ("crest"). In addition to being an incomplete dominant gene, the "hairless" gene has a prenatal lethal effect when homozygous. Zygotes affected with double hairless genes never develop into puppies, and are reabsorbed in the womb. All Hairless Chinese Crested Dogs are therefore heterozygous.

The Hairless variety can vary in amount of body hair. Hair on the muzzle, known as a beard, is not uncommon. A true Hairless often does not have as much furnishings (hair on the head, tail, and paws). The difference between a very hairy Hairless and a Powderpuff is that the Hairless has a single coat with hairless parts on the body, while the Powderpuff has a thick double coat. The skin of the Hairless comes in a variety of colors, ranging from a pale flesh to black. Hairless Chinese Crested Dogs often lack a full set of premolar teeth.

A Powderpuff has a long, soft coat. Both Hairless and Powderpuff varieties can appear in the same litter. The look of the Powderpuff varies according to how it is groomed. When its hair is completely grown out on its face, it strongly resembles a terrier; however, the Powderpuff is usually shaved around the snout as a standard cut. The Powderpuff Chinese Crested Dog is an elegant and graceful dog who makes a loving companion, playful and entertaining. The Powderpuff's coat is long and silky soft. Ears are large and erect.

The amount of body hair on the Hairless variety varies quite extensively, from the true hairless which has very little or no body hair and furnishings, to what is called a "hairy Hairless" dog, which, if left ungroomed, often grows a near-full coat of hair. These hairy Hairless dogs are not a mix between Powderpuffs and Hairless Chinese Crested Dogs, but are merely a result of a weaker expression of the variable Hairless gene. The mutation responsible for the hairless trait was identified in 2008.

Behavior

The Chinese Crested Dog Chinese Crested is an elegant and graceful dog who makes a loving companion, playful and entertaining. The Puff's coat is long and silky soft. Ears are large and erect. It is a family friendly breed, not aggressive toward children or other animals. They do not make good kennel dogs, since they love the companionship of their family. This breed tends to be on the timid side with strangers if not properly socialized at an early age. Odorless, non-shedding, and hypo-allergenic, these are great dogs for allergy sufferers. They have been described as having "a supermodel look, with a saint personality." Chinese Crested Dogs are very affectionate, lively, playful, and love to be cuddled. This breed is exceptionally loving and likes to hug & smile. Many are known to be wonderful "singers." They are great with children, very forgiving, therefore should not be taken advantage of with rough handling. They are an entertaining companion, intelligent, and very willing to learn. He needs firm but gentle training beginning when he is still very young.

Both varieties require certain amounts of grooming. The Powderpuff is entirely covered with a double, very soft, straight coat. Although a Powderpuff's coat does not continuously grow, it can grow to be quite long at full length. A weekly bath and frequent brushing will help prevent matting. For an optimal coat, never brush when dry or dirty. A light spray of water or grooming spray to their coat is recommended before brushing. Many choose to shave their Powderpuff in a "Pony Cut" leaving long hair on the bottom of legs, tail, head and crest for an easy care coat. Powderpuffs are very clean and have no odor. This breed has "little to no shedding".

Maintenance of the Hairless variety's skin is similar to maintaining human skin and as such it can be susceptible to acne, dryness, and sunburn. Hypoallergenic or oil-free moisturizing cream can keep the skin from becoming too dry when applied every other day or after bathing. Burning can occur in regions that are subject to strong UV radiation, especially in lighter-skinned dogs. Many owners apply baby sunscreen to their pets before spending time in strong sun. Some Chinese Crested Dogs have skin allergies to lanolin, so be cautious when using any products that contain it.

Unless the dog is a "true" Hairless (one with virtually no hair growth on non-extremities), trimming and/or shaving is often performed to remove excess hair growth.

The Chinese Crested Dog is further distinguished by its hare foot (having more elongated toes), as opposed to the cat foot common to most other dogs. Because of this the quicks of Cresteds run deeper into their nails, so care must be taken not to trim the nails too short to avoid pain and bleeding.

Powderpuffs enjoy getting outdoors for daily exercise, although they are not a high energy breed. They are great for apartment or city living, but being very versatile, also love country living and long hikes.

Being a very intelligent breed, this dog does well in obedience type sports. Consistency is a must, however this breed can be relatively sensitive and should have a gentle trainer. The Powderpuff is great at learning and performing tricks.

Health

The Powderpuff is not affected by many of the congenital diseases found in other toy breeds. They are, however, prone to some of these conditions listed. Eye problems such as lens luxation, glaucoma, and PRA (Progressive Retinal Atrophy), luxating patellas, and Legg-Perthes disease. The Powderpuff should have full dentition, not missing or crooked teeth, as is accepted in their sibling the Hairless variety.

Chinese Crested Dogs have what is called a "primitive mouth". This means that most of their teeth are pointy, like their canines. Hairless varieties of the Cresteds can be prone to poor dentition. Poor dentition may include missing or crowded teeth and teeth prone to decay when not properly cared for. Most dogs of the Powderpuff variety have few, if any, dental defects.

Eyes are a concern within the breed, with many suffering from a painful and blinding inherited eye disease called Primary Lens Luxation (PLL). The Chinese Crested Dog can also have at least two forms of progressive retinal atrophy (PRA) which can eventually lead to blindness as well. For PLL and also one of the forms of PRA, there exists a genetic test, to determine if a dog is a "carrier, clear, or affected." prcd-PRA. Since the test for prcd-PRA can only reveal the existence of affected or carrier status of this one form of PRA, breeders and owners of the breed should still have regular eye exams by veterinary ophthalmologists. The breed also suffers from another eye disease called Keratoconjunctivitis sicca or dry eye syndrome (DES).

Along with Kerry Blue Terriers, Chinese Crested Dogs can develop canine multiple system degeneration (CMSD) also called progressive neuronal abiotrophy (PNA) in Kerry Blue Terriers. This is a progressive movement disorder that begins with cerebellar ataxia between 10 and 14 weeks of age. After 6 months of age, affected dogs develop difficulty initiating movements and fall frequently. The gene responsible has been mapped to canine chromosome 1.

As with all other toy breeds, the Chinese Crested Dog can be prone to patellar luxation. This inheritable condition is caused by shallow knee joints (stifles) and results in kneecaps that pop out of place. Its onset is often at a young age, and can cause temporary to permanent lameness based on the severity. Breeders should have their stock certified free of patellar luxation. Many countries' kennel clubs maintain a centralised registry for health results.

Allergy and autoimmune diseases have been observed in the breed. Some food allergies can also cause skin breakouts, like excess blackheads, pimples and dryness. It has been observed that this breed has an allergy to chicken and many owners opt for a chicken free diet or a homemade one. The severity of these ailments, which can lead to the premature death of the dog, means this is something breeders need to take seriously in order to avoid it becoming a problem for the breed.



Jack Russell Terrier Breed Description - Cross #2

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.
