Hybrid Description

The Jack Tzu is not a purebred dog. It is a cross between the Jack Russell Terrier and the Shih Tzu. 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.




Shih Tzu Breed Description - Cross #2

The Shih Tzu is a sturdy little dog with a small muzzle and normally has large dark brown eyes. The Chinese have described their head shapes as "owl head" and "lion head", and their mouth as "frog mouth". They have a soft and long double coat that will tangle and mat easily if not brushed at least every 2 or 3 days. Floppy ears are covered with long fur, and the heavily furred tail is carried curled over the back. The coat may be of any color, though white and with blazes of grey are frequently seen.

The traditional long silky coat, which tends to reach the floor, requires daily brushing to avoid tangles. Because of their long coat and fast-growing hair, regular grooming is necessary and important, which may be expensive and should be taken into account when considering adopting one of this breed. Often, the coat is clipped short to simplify care, but the coat still requires daily brushing. For conformation showing, the coat must be left in its natural state, though trimming for neatness around the feet and anus is allowed. The shorter cut is typically called a "puppy cut" or a "teddy bear cut" when the puppy cut is accompanied by a fuller, rounder face, resembling a cute and cuddly stuffed animal.

Behavior

Lively, very active, and independent, this calm, gentle, merry dog needs lots of love and attention. He is the most outgoing of the Asian breeds. He is indifferent toward strangers and barks to announce their presence. He needs firm and gentle training.

Although small in size, they are well-known for their largely fun and playful personality, and calm and friendly temperament. They are able to adapt well in different situations. Due to their highly independent nature, they are not considered the most obedient breed.

He was meant for the city but needs exercise, including daily walks. He does not like being left alone. He requires daily brushing and combing. It is strongly recommended that the hair on his head be tied back out of his eyes. He needs a monthly bath and regular checking of the eyes. He cannot bear intense heat.

Health

Heart Disease
Shih Tzu's are prone to multiple types of heart disease. The condition may have a poor prognosis depending on when it is diagnosed and the stage of the disease when it is discovered.

Brachycephaly
Due to the ideal of beauty regarding the shape of the face the skull malformation brachycephaly was increased by breeding selection. This short nose causes problems like skin sensitivities such as dermatitis, bumps, and rashes.

Eye issues
It is very common for Shih Tzu's to develop eye problems at any age, and even more so once they are older. Most veterinarians will recommend eye drops to assist with any eye irritations. Some dogs have allergies which causes excess discharge around the eye. Older Shih Tzu are known to develop cataracts which can be corrected with surgery. If not treated, the dog may become blind in the eye that has the cataract. The distinctive large eyes can easily be scratched which may cause an ulcer. The dog will normally have the injured eye closed or half closed and may have excessive tears. The most common problem of Shih Tzus concerning eye conditions is the formation of epiphora caused by the fur on the eyelids scratching the conjunctiva and the cornea. However this can be mediated by the application of prescribed eye drops from a veterinarian.

Hair issues
Untrimmed hair can be an issue. This is remedied with a top knot or a short puppy cut. Shih Tzus have hair which can grow lengthy. Long hair is required as a show coat and is required generally to be brushed or groomed once a day. Hair longer than a puppy cut often causes issues, including hair covering the eyes of the dog, preventing good visual acuity.

Ear issues
A very common issue for Shih Tzu's is the development of ear infections, as they have a long coat and hair grows in their ears. If ears are not plucked and cleaned often, ear infections will reoccur and need to be treated with ear cleaner and possibly medication, prescribed by the veterinarian. Ear infections may be spotted by an odor coming from the ears, as well as frequent shaking of the head and scratching of the ears.

Skin sensitivities
The Shih Tzu's skin is particularly sensitive and prone to allergies. Ideally, they should be bathed every two to six months to maintain hygiene and prevent skin irritations. They are also prone to stomach issues, and most have delicate appetites.
