Great Wolfhound

The Great Wolfhound is a cross between the Great Pyrenees and the Irish Wolfhound. Because each hybrid inherits a unique combination of traits from both parents, we recommend thoroughly researching both breeds before choosing a Great Wolfhound. Pay special attention to temperament, health issues, and care requirements, as your dog may express characteristics from either parent breed.

Great Pyrenees

Great Pyrenees

The Great Pyrenees is a large and powerful breed that presents an elegant yet substantial appearance, embodying strength and majesty in equal measure. Male Great Pyrenees typically stand between 27 and 32 inches at the shoulder and weigh 100 pounds or more, while females range from 25 to 29 inches in height with weights starting at 85 pounds. The breed possesses a well-proportioned body that is slightly longer than tall, with a level backline and a broad chest that provides impressive substance without appearing heavy or cumbersome. Their sturdy bone structure and well-developed musculature reflect their heritage as working guardians capable of defending livestock against formidable predators. The most striking feature of the Great Pyrenees is their magnificent double coat, which consists of a long, thick, coarse outer layer that can be either straight or slightly wavy, and a dense, woolly undercoat that provides excellent insulation against harsh weather conditions. The coat is predominantly white, though markings of gray, badger, reddish-brown, or tan may appear on the ears, head, tail, and occasionally on the body, typically covering no more than one-third of the dog. A distinctive mane of longer fur develops around the neck and shoulders, appearing more pronounced in males, while feathering adorns the backs of the legs and the tail. The Great Pyrenees possesses a wedge-shaped head that appears slightly rounded at the crown, with a muzzle roughly equal in length to the skull. Their eyes are medium-sized, almond-shaped, and dark brown in color, expressing an intelligent and contemplative demeanor. The ears are V-shaped with rounded tips, set at eye level and carried close to the head. A unique breed characteristic is the presence of double dewclaws on the rear legs, which served historically to provide additional traction in mountainous terrain. The tail is long enough to reach the hocks and is carried low in repose but may rise in a wheel or slight curve when the dog is alert or excited.

Key Characteristics

Temperament
Temperament Temperament Temperament Temperament Temperament Temperament The breed's strong guarding instincts manifest in their natural tendency to bark, particularly at night when they would traditionally patrol against predators. They are typically reserved with strangers, observing newcomers carefully before warming up, though they should never display unprovoked aggression. Great Pyrenees generally coexist peacefully with other pets, especially when raised together, viewing them as part of their flock to protect. Their exercise needs are moderate compared to many large breeds, as they are not highly energetic dogs, preferring calm supervision of their domain to vigorous activity. They thrive in environments where they have space to roam and a purpose to fulfill.
Health Considerations
Health Considerations Health Considerations Health Considerations Health Considerations Health Considerations Health Considerations Additional health concerns include Addison's disease, an endocrine disorder where the adrenal glands produce insufficient hormones, leading to symptoms such as lethargy, vomiting, and weakness that can be life-threatening if undiagnosed. Eye conditions including entropion, where the eyelid rolls inward causing irritation, and cataracts have been documented in the breed. Osteosarcoma, an aggressive bone cancer that disproportionately affects large and giant breeds, occurs with some frequency. Some bloodlines may be predisposed to certain bleeding disorders or immune-mediated conditions. Regular veterinary examinations, appropriate health screenings, and awareness of early warning signs help ensure the best possible health outcomes for these magnificent guardians.

Irish Wolfhound

Irish Wolfhound

The Irish Wolfhound holds the distinction of being the tallest of all dog breeds, presenting a commanding and awe-inspiring presence that combines great size with remarkable grace. Male Irish Wolfhounds must stand at least 32 inches at the shoulder and weigh a minimum of 120 pounds, though many individuals exceed these minimums considerably, with some reaching 34 inches or taller and weighing up to 180 pounds. Females are somewhat smaller but still impressive, standing at least 30 inches tall and weighing a minimum of 105 pounds. The breed standard emphasizes that great size is the desideratum to be aimed at, with the goal of establishing a breed that averages 32 to 34 inches in males while showing requisite power, activity, courage, and symmetry. The Irish Wolfhound is described as a rough-coated, Greyhound-like breed, possessing the general type of a galloping hound but with far more substance and power. Their body is long with a well-sprung rib cage and great breadth across the hips, supported by heavily boned forelegs that are quite straight with elbows well set under the body. The muscular development is strong yet elegant, allowing for the speed and power required of a breed that historically hunted wolves and Irish elk. Despite their massive size, Irish Wolfhounds should move with an easy and active gait, never appearing cumbersome or heavy. The coat is rough and hard, particularly wiry and long over the eyes and under the jaw, creating a distinctive bearded appearance. Recognized colors include gray, brindle, red, black, pure white, and fawn, with gray and brindle being most commonly seen. The head is long and carried high on a well-arched neck of considerable length and strength. The ears are small and have a Greyhound-like carriage, folded back against the head in repose but sometimes pricking slightly when alert. The eyes are dark and express a gentle, dignified demeanor. The tail is long, moderately thick, and carried with an upward sweep with a slight curve toward the extremity, contributing to the breed's noble silhouette.

Key Characteristics

Temperament
Temperament Temperament Temperament Temperament Temperament Temperament Energy levels in the Irish Wolfhound are moderate to low compared to many breeds, as they mature into calm companions content with regular exercise but not requiring intense activity. However, they need space to stretch their long legs and benefit from opportunities to run in safely enclosed areas. Their prey drive remains intact, and they should be supervised around smaller animals. Irish Wolfhounds are typically friendly toward strangers and do not make effective guard dogs despite their intimidating appearance. They generally coexist peacefully with other dogs, though their sheer size requires supervision during play with smaller breeds.
Health Considerations
Health Considerations Health Considerations Health Considerations Health Considerations Health Considerations Health Considerations Orthopedic conditions are common due to their rapid growth rate and heavy frame. Hip and elbow dysplasia affect the breed, causing progressive joint degeneration and mobility issues. Osteochondritis dissecans, a developmental condition affecting joint cartilage, can cause lameness in young dogs. Liver shunts, abnormal blood vessels that bypass the liver, have been documented and can cause neurological symptoms. Rear-end weakness affects a significant percentage of older dogs, causing progressive coordination problems in the hindquarters. Given these substantial health concerns, prospective owners should seek puppies from breeders who conduct thorough health testing and prioritize longevity in their breeding programs.
