Shel-Aussie
The Shel-Aussie is a cross between the Australian Shepherd and the Shetland Sheepdog. Because each hybrid inherits a unique combination of traits from both parents, we recommend thoroughly researching both breeds before choosing a Shel-Aussie. Pay special attention to temperament, health issues, and care requirements, as your dog may express characteristics from either parent breed.
Australian Shepherd
The Australian Shepherd is a medium-sized, athletic herding dog that presents a picture of agility, strength, and endurance perfectly suited to demanding ranch work. Males typically stand between 20 and 23 inches at the shoulder and weigh 50 to 65 pounds, while females measure 18 to 21 inches and weigh 40 to 55 pounds. The breed exhibits a slightly longer than tall body proportion, with a deep chest and well-sprung ribs that provide ample lung capacity for sustained physical activity. Their movement is smooth, free, and effortless, demonstrating the balanced structure essential for a working herding dog that must remain tireless throughout long days of demanding labor in varied terrain and weather conditions. The Australian Shepherd possesses a medium-length double coat that is weather-resistant and adapted for various climatic conditions encountered on working ranches. The outer coat is straight to wavy with moderate texture, while the undercoat varies in density according to climate, becoming thicker in colder regions. One of the breed's most striking features is its remarkable color variety, including blue merle, red merle, solid black, and solid red, with or without white markings and copper points. The merle patterns create a marbled effect that is particularly eye-catching and distinctive to the breed. Feathering appears on the backs of the legs, and males display a more pronounced mane and frill around the neck. The head is clean-cut with a slightly rounded skull and a moderate stop between the forehead and muzzle. Eyes may be brown, blue, amber, or any combination thereof, including flecks and marbling, which contributes to the breed's remarkably expressive and intelligent appearance. Ears are triangular and set high, breaking forward or to the side when the dog is alert and attentive. A distinguishing characteristic is the naturally bobbed tail or docked tail that is typically four inches or shorter. The overall expression conveys intelligence, eagerness, and alertness, reflecting the breed's keen working ability and responsive nature that has made them invaluable partners to ranchers.
Key Characteristics
Temperament Temperament Temperament Temperament Temperament Temperament The breed's herding heritage manifests in their attention to moving objects and their desire to keep their family group together. Without proper outlets, these instincts may lead to nipping at heels or chasing vehicles. Australian Shepherds excel in various dog sports including agility, herding trials, and obedience competitions where their intelligence and athletic ability can shine. They are happiest when given a job to do and thrive in active households where they can participate in regular activities with their owners. Their high energy levels and need for engagement make them best suited for experienced dog owners who understand working breeds.
Health Considerations Health Considerations Health Considerations Health Considerations Health Considerations Health Considerations One of the most significant health concerns for Australian Shepherds is the MDR1 gene mutation, which affects approximately 50 percent of the breed population as carriers. This genetic variation causes sensitivity to certain medications including some common heartworm preventatives, anti-diarrheal drugs, and anesthetics. Dogs with this mutation can experience severe adverse reactions to these drugs, making genetic testing essential before administering any medications. Epilepsy and thyroid disease are also seen in the breed with some regularity. Additionally, Australian Shepherds may be predisposed to certain cancers including lymphoma and hemangiosarcoma, particularly as they age, making regular wellness examinations important for early detection.
Shetland Sheepdog
The Shetland Sheepdog is a small to medium-sized herding dog that stands between 13 and 16 inches at the shoulder and typically weighs 14 to 27 pounds. Despite their smaller stature, they present a picture of strength and agility with a well-balanced, symmetrical outline that suggests both refinement and working capability. The body is moderately long in proportion to height, with a deep chest that reaches to the elbow and well-sprung ribs that provide adequate lung capacity. Their movement is smooth, effortless, and ground-covering, with the hallmark grace and economy of motion that reflects their herding heritage. Often mistaken for a miniature Rough Collie, the Sheltie is actually a distinct breed that was developed independently on the remote Shetland Islands off the coast of Scotland. The Shetland Sheepdog possesses a magnificent double coat that is one of its most striking and recognizable features. The outer coat consists of long, straight, harsh-textured hair, while the undercoat is short, dense, and furry, providing excellent insulation against the harsh maritime weather of their island homeland. The mane and frill around the neck are particularly abundant in males, giving the dog an impressive and dignified appearance. Recognized colors include sable ranging from golden to deep mahogany, tricolor with black, white, and tan markings, blue merle with a marbled gray and blue pattern, black and white, and black and tan. White markings typically appear on the chest, legs, and collar, adding to the breed's elegant presentation. The head is refined and elegant with a long, wedge-shaped appearance when viewed from above or the side. The skull is flat with a slight but definite stop, and the muzzle is equal in length to the skull, creating a balanced profile. Almond-shaped eyes are set obliquely and are dark in color, except in blue merles where blue or merle eyes are permitted and add to their striking appearance. The ears are small, flexible, and set high, carried three-quarters erect with the tips folding forward, giving an alert and intelligent expression. The overall appearance conveys sensitivity, intelligence, and willingness that characterizes this devoted and versatile breed.
Key Characteristics
Temperament Temperament Temperament Temperament Temperament Temperament The breed's herding instincts remain strong, and Shelties may attempt to herd children, other pets, or moving objects by circling and occasionally nipping at heels. These behaviors can be redirected through training and by providing appropriate outlets such as agility courses, herding trials, or other dog sports where their natural abilities can shine. Their sweet, gentle temperament combined with their intelligence and trainability makes them adaptable to many living situations, though they require regular mental stimulation and physical exercise to remain content. Shelties are peaceful with other animals and polite with everyone they meet once they become familiar with them.
Health Considerations Health Considerations Health Considerations Health Considerations Health Considerations Health Considerations Von Willebrand disease, a blood clotting disorder, affects an estimated 23 percent of Shetland Sheepdogs to varying degrees. Dogs with this condition may experience excessive bleeding from minor injuries or during surgical procedures. The MDR1 gene mutation, which causes drug sensitivity, is also present in the Sheltie population and requires genetic testing before administering certain medications. Dermatomyositis, sometimes called Sheltie Skin Syndrome, is an inherited inflammatory condition affecting the skin, muscles, and blood vessels that occurs primarily in Shelties and Collies. Thyroid disease, epilepsy, patellar luxation, and gallbladder mucoceles are additional conditions seen in the breed. Responsible breeders conduct health testing to minimize the risk of passing these conditions to offspring.
Important to Remember
Each hybrid dog is unique and may inherit any combination of traits from either parent breed. The information above represents the characteristics of the purebred parent breeds. Your Shel-Aussie may favor one parent over the other or display a blend of both. We strongly encourage you to read the complete breed profiles for both the Australian Shepherd and Shetland Sheepdog to fully understand the range of possible temperaments, health concerns, and care requirements.
