Hybrid Description

The Tibetan Golden Mastiff is not a purebred dog. It is a cross between the Golden Retriever and the Tibetan Mastiff. 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.

Golden Retriever Breed Description - Cross #1

The Golden Retriever is a large, strongly-built breed with a dense water-repellant wavy coat. As a dog with origins in pedigree breeding, and due to its widespread historical popularity, some regional variations have emerged in the breed; therefore, there are three sub-types of the Golden Retriever that reflect the typical variations in dimensions and coat. However, all Golden Retrievers are blonde, yellow, or gold in color and all sub-types are susceptible to the same health problems.

British type Golden Retrievers are prevalent throughout Europe and Australia, and are distinguished from the North American lines by the official breed standards. The muzzle of the British dog is wider and shorter, and its forehead is blockier. Its legs are shorter, its chest is deeper, and its tail is slightly shorter. Due to these features, a British type usually weighs more than an American or Canadian. Males will be between 56 and 61 cm (22 and 24 in) at the withers; females will be slightly shorter, at between 51 and 56 cm (20 and 22 in). Acceptable or expected weights are not specified in the UK standard, but the KC standard calls for a level topline and straight hindquarters without the slight rear angulation found in American lines. The eyes of the European type are noted for their roundness and darkness, which is in contrast to the triangular or slanted composition of their American counterparts. A Golden Retriever of British breeding can have a coat color of any shade of gold or cream; red or mahogany are not permitted colors of coat. Originally, cream was an unacceptable color in the UK standard, but the standard was revised in 1936 to include cream. At the time of this revision, it was agreed the exclusion of cream as a color was a mistake, as the original "yellow" retrievers of the 19th century were actually lighter in color than was permitted by the standards that were used before 1936. As with American lines, white is an unacceptable color in the show ring. The British KC standard is used in all countries except the USA and Canada. Golden Retrievers have muscular bodies with great endurance, owing to their origins as hunting and gundogs.

American Golden Retrievers are taller than the British type, but retain its thick coat. The American Goldens are lankier and less stocky than British types. Males will stand between 23 and 24 in (58 and 61 cm) in height at the withers; females will be 21.5–22.5 in (55–57 cm). Their coat is dense and water-repellent, and comes in various shades of lustrous gold with moderate feathering. When trotting, they have a free, smooth, powerful, and well-coordinated gait; as the dog runs, its feet converge towards the centre of the line of balance. The American standard also makes requirements about the proportion, substance, head and skull, neck, body, topline, forequarters, and hindquarters; in these respects, the American type Retriever is the same as Golden Retrievers that conform to other national standards. American breeders of Golden Retrievers sometimes import their dogs from Britain, in order to take advantage of the temperament and appearance of the British types.

The Canadian Golden Retriever has a thinner coat and stands taller than other varieties of Golden Retriever. As with American Golden Retrievers, Canadians are often taller and leaner than their British counterparts. However, Canadian retrievers differ in the density and color of their coats, which are commonly thinner and darker than those of Americans.

Behavior

The Golden Retriever is considered an intelligent, gentle natured and very affectionate breed of dog. As is typical with retriever breeds, the breed is generally calm and biddable, being very easy to train and extremely keen to please their master. The breed is known to make excellent pets and family dogs, being generally extremely tolerant of children and keen to accompany any member of the family in a range of activities. Due to their affable natures, the breed is often completely devoid of guarding instincts.

The breed usually retains many of their gundog traits and instincts including an excellent sense of smell and a strong instinct to retrieve; even among those not trained as gundogs it is typical for Golden Retrievers to present their owners with toys or other objects. Compared to other retriever breeds the Golden Retriever is typically quite slow to mature.

He is not suited to apartment life unless he gets lots of exercise. He hates being left alone. He requires brushing once or twice weekly, as well as combing during the shedding season.

Health

Golden Retrievers are a generally healthy breed; they have an average lifespan of 12 to 13 years. Irresponsible breeding to meet high demand has led to the prevalence of inherited health problems in some breed lines, including allergic skin conditions, eye problems and sometimes snappiness. These problems are rarely encountered in dogs bred from responsible breeders.



Tibetan Mastiff Breed Description - Cross #2

The Tibetan Mastiff is considered a primitive breed. It typically retains the hardiness which would be required for it to survive in Tibet and the high-altitude Himalayan range, including the northern part of Nepal, India and Bhutan. Instinctive behaviors including canine pack behavior contributed to the survival of the breed in harsh environments. It is one of the few primitive dog breeds that retains a single estrus per year instead of two, even at much lower altitudes and in much more temperate climates than its native climate. This characteristic is also found in wild canids such as the wolf. Since its estrus usually takes place during late fall, most Tibetan Mastiff puppies are born between December and January.

Its double coat is long, subject to climate, and found in a wide variety of colors, including solid black, black and tan, various shades of "red" (from pale gold to deep red) and bluish-gray (dilute black), often with white markings.

The coat of a Tibetan Mastiff lacks the unpleasant "big-dog" smell that affects many large breeds. The coat, whatever its length or color(s), should shed dirt and odors. Although the dogs shed somewhat throughout the year, there is generally one great "molt" in late winter or early spring and sometimes another, lesser molt in the late summer or early fall. (Sterilization of the dog may dramatically affect the coat as to texture, density, and shedding pattern.)

Behavior

As a flock guardian dog in Tibet, and in the West, it uses all the usual livestock guardian tactics (e.g., barking, scent-marking perimeters) to warn away predators and avoid direct confrontations.

As a socialized, more domestic dog, it can thrive in a spacious, fenced yard with a canine companion, but it is not an appropriate dog for apartment living. The western-bred dogs are generally more easy-going, although still somewhat aloof with strangers. Through hundreds of years of selective breeding for a protective flock and family guardian, the breed has been prized for being a nocturnal sentry, keeping would-be predators and intruders at bay, and barking at unidentified sounds throughout the night. Leaving a Tibetan mastiff outside all night with neighbors nearby is not recommended. They often sleep during the day, making them more active, alert and aware at night.

Like all flock guardian breeds, they are intelligent and stubborn to a fault, so obedience training is recommended (although it is only mildly successful with some individuals) since this is a strong-willed, powerful-bodied breed. Unless they are to be used exclusively as livestock guardians, socialization training is also critical with this breed, because of their reserved nature with strangers and guardian instincts. They can be excellent family dogs – depending on the family. Owners must understand canine psychology and be able and willing to assume the primary leadership position. Lack of consistent, rational discipline can result in the creation of dangerous, unpredictable dogs. The protectiveness of Tibetan mastiffs requires alertness and planning by the owner, in order to avoid mishaps when the dog is merely reacting as a guardian. The breed is not recommended for novice dog owners.

Health

he breed has fewer genetic health problems than many breeds, but cases can be found of hypothyroidism, entropion, ectropion, skin problems including allergies, autoimmune problems including demodex, missing teeth, malocclusion (overbite, underbite, wry mouth), cardiac problems, seizures, epilepsy, progressive retinal atrophy (PRA), cataract, and small ear canals with a tendency for infection. As with most large breeds, some will suffer with elbow or hip dysplasia.

Canine inherited demyelinative neuropathy (CIDN), an inherited condition, appeared in one of the prominent lines of Tibetan Mastiffs in the early 1980s. Unfortunately, known carriers were bred extensively and are behind many lines still being actively bred. Because the mode of inheritance appears to be as a simple recessive, continued inbreeding can still produce affected puppies.

Hypothyroidism is fairly common in Tibetan Mastiffs, as it is in many large "northern" breeds. They should be tested periodically throughout their lives using a complete thyroid "panel". (Simple T2/T4 testing is virtually useless.) However, because the standard thyroid levels were established using domestic dog breeds, test results must be considered in the context of what is "normal" for the breed, not what is normal across all breeds. Many dogs of this breed will have "low" thyroid values but no clinical symptoms. Vets and owners differ on the relative merits of medicating dogs which test "low", but are completely asymptomatic. Some researchers think that asymptomatic hypothyroidism may have been adaptive in the regions of origin for many breeds, since less nutrition is required for the dog to stay in good condition. Therefore, attempts to eliminate "low thyroid" dogs from the Tibetan Mastiff gene pool may have unintended consequences for the breed.

The Tibetan mastiff was able to adapt to the extreme highland conditions of the Tibetan Plateau very quickly compared to other mammals such as the yak, Tibetan antelope, snow leopard, and the wild boar. The Tibetan mastiff's ability to avoid hypoxia in high altitudes, due to its higher hemoglobin levels compared to low-altitude dogs, was due to prehistoric interbreeding. In 2020, a genomic analysis indicates that a ghost population of an unknown wolf-like canid which is deeply-diverged from modern Holarctic wolves and dogs has contributed the EPAS1 allele found in both Himalayan wolves and dogs, and this allows them to live in high altitudes.
