Aussie-Flat
The Aussie-Flat is a cross between the Australian Shepherd and the Flat-Coated Retriever. Because each hybrid inherits a unique combination of traits from both parents, we recommend thoroughly researching both breeds before choosing a Aussie-Flat. 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, well-balanced dog that combines athleticism with agility and endurance. Males typically stand 20 to 23 inches at the withers and weigh between 50 and 65 pounds, while females measure 18 to 21 inches and weigh 40 to 55 pounds. The breed presents a slightly rectangular silhouette, being marginally longer than tall with an ideal height-to-length ratio of approximately 5:6. Their body is strongly built with moderate bone and substance, never appearing cloddy or overly light, with males exhibiting a more substantial masculine appearance and females showing a slightly more refined feminine build. The Australian Shepherd possesses a distinctive double coat designed to protect against varying weather conditions. The outer coat is medium length with straight to slightly wavy hair of moderate texture, while the dense undercoat varies in thickness depending on climate. Significant feathering appears on the backs of the forelegs, and males typically display a more pronounced mane around the neck and chest area. The breed comes in four recognized colors: blue merle, red merle, solid black, and solid red, all of which may appear with or without white markings and copper points. White markings commonly appear on the chest, legs, muzzle, and as a blaze on the face. The head of the Australian Shepherd is clean-cut with a slightly rounded skull and a moderate stop between the forehead and muzzle. The muzzle tapers slightly toward the nose, which is black in blue merle and black dogs, and liver-colored in red merle and red dogs. Perhaps the most striking feature is their expressive eyes, which can be brown, blue, amber, or any combination thereof, including marbled or flecked patterns. The ears are triangular and set high, breaking forward or to the side when alert. Some Australian Shepherds are born with a naturally bobbed tail, while others have full-length tails that are traditionally docked.
Key Characteristics
Temperament Temperament Temperament Temperament Temperament Temperament Australian Shepherds form intensely loyal bonds with their families and are often described as velcro dogs because of their tendency to remain close to their owners at all times. While deeply devoted and affectionate with family members, they can be reserved or cautious around strangers, making early socialization essential for developing well-rounded temperaments. They are protective without being aggressive and make excellent watchdogs. These dogs do not tolerate being left alone for extended periods and may develop separation anxiety if isolated from their family, as they thrive on companionship and inclusion in household activities.
Health Considerations Health Considerations Health Considerations Health Considerations Health Considerations Health Considerations A critical health consideration unique to Australian Shepherds and related breeds is the MDR1 gene mutation, which affects approximately 50 percent of the breed population. This genetic variant causes sensitivity to certain medications, including ivermectin commonly found in heartworm preventatives, as well as some anesthetics and anti-diarrheal drugs. Dogs with this mutation can experience severe neurological reactions to these medications. Genetic testing is available and recommended for all Australian Shepherds to identify carriers. Additional health concerns include epilepsy, which typically manifests between six months and three years of age, autoimmune thyroiditis, various cancers including lymphosarcoma and hemangiosarcoma, von Willebrand disease affecting blood clotting, and degenerative myelopathy.
Flat-Coated Retriever
The Flat-Coated Retriever is an elegant, medium to large-sized sporting dog that combines strength with refined athleticism. Males stand 23 to 24.5 inches at the withers, while females measure 22 to 23.5 inches, with weights ranging from 60 to 80 pounds, females typically being at the lower end of that range. The breed presents a distinctive silhouette that is slightly longer than tall, with moderate bone that is flat or oval rather than round. The overall impression is one of a strong but elegant dog, never appearing cobby, short-legged, rangy, or coarse, built for both endurance and agility in the field. The coat is the breed's signature feature, lying flat and close to the body with a lustrous sheen that reflects good health and condition. The hair is straight or only slightly wavy, of medium length, and dense enough to provide protection from weather, water, and ground cover. Generous feathering adorns the ears, chest, backs of the forelegs, thighs, and underside of the tail, though never to excess. Males often display a more pronounced mane of thicker hair extending from the neck across the withers and shoulders. Only two colors are accepted in the breed standard: solid black, which is the most common, and liver. The coat's dense, water-resistant quality reflects the breed's heritage as a waterfowl retriever. The head of the Flat-Coated Retriever is long and cleanly molded, creating an impression of skull and muzzle being cast in one continuous piece. The skull is fairly flat with minimal stop, blending smoothly into the deep, strong muzzle that must be adequate to carry large game birds. The expression is intelligent and friendly, conveyed through dark brown or hazel almond-shaped eyes set well apart. The ears are pendant, relatively small, and set close to the head. The nose is large with well-opened nostrils, black in black dogs and brown in liver dogs. The neck is long and slightly arched, flowing smoothly into well-laid-back shoulders. The chest is deep and moderately broad, with a prominent forechest, while the back is strong and level. The tail is fairly straight, carried happily but not much above the level of the back.
Key Characteristics
Temperament Temperament Temperament Temperament Temperament Temperament Flat-Coated Retrievers are deeply social dogs that thrive on human companionship and form strong bonds with their families. They are wonderful with children, patient and gentle, and typically get along well with other dogs and pets when properly socialized. These dogs suffer when left alone for extended periods and may develop destructive behaviors or excessive vocalization from loneliness. They are happiest when included in family activities, whether hiking, swimming, or simply relaxing together. Their exuberant greeting style, which may include jumping and tail-wagging enthusiasm, can be overwhelming for some visitors, making early training in polite manners beneficial. The combination of intelligence, athleticism, and affectionate nature makes them versatile companions for active families who can match their energy and emotional needs.
Health Considerations Health Considerations Health Considerations Health Considerations Health Considerations Health Considerations Eye conditions affecting the breed include glaucoma, which typically develops around five to six years of age and can lead to painful pressure buildup and vision loss if untreated. Regular ophthalmologic examinations are recommended to detect early signs of this condition. Progressive retinal atrophy, causing gradual vision deterioration, also occurs in the breed. Dilated cardiomyopathy, a condition affecting heart muscle function, has been identified in Flat-Coated Retrievers and warrants cardiac screening. Luxating patellas, where the kneecap slides out of position, may cause lameness and discomfort. Epilepsy and kidney disease have also been reported in the breed. Despite these health challenges, many Flat-Coated Retrievers live happy, active lives, and awareness of potential issues allows for proactive monitoring and early intervention when problems arise.
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 Aussie-Flat 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 Flat-Coated Retriever to fully understand the range of possible temperaments, health concerns, and care requirements.
