Size and Build
An Australian Shepherd typically stands between 51-58 cm tall at the shoulder for males, with females slightly shorter at 46-53 cm. Males generally weigh between 23-29 kgs, while females tend to weigh 14-20 kgs. This breed falls into the medium-sized category, with a muscular, well-balanced frame that is slightly longer than tall to aid agility and endurance. The overall physique conveys strength without unnecessary bulk, ideal for active herding duties.
Coat and Colors
The dog’s coat is medium-length, thick, and weather-resistant, exhibiting either a straight or slightly wavy texture with a dense undercoat. Common colours recognised by American breed standards include black, blue merle, red, and red merle, often combined with tri-colour patterns and white and copper markings. White patches are allowed on the chest, muzzle, face blaze, underbelly, and legs without overpowering the head's coloration. Tan points may be present in any pattern. The coat thickens during cold seasons and sheds moderately in spring and autumn, requiring routine grooming to control.
Distinctive Features
The head is clean and slightly domed with a well-defined stop. Eyes are almond-shaped and expressive, coming in shades of brown, blue, amber, or different combinations, often marbled or flecked. Ears are medium, triangular with rounded tips, set high and carried upright or semi-erect, commonly folding forward when alert or working. The tail is of moderate length with feathering and often naturally bobbed, a trait accepted under breed guidelines.
Gender Differences
Males tend to have a larger frame with a more pronounced mane of fur around the neck, while females usually have a more streamlined build and slightly less dense coat. Typically, males may show a bit more territoriality whereas females can be more nurturing, though personality can vary widely. Breed shows emphasise balanced body lines, even gait, and vivid, clear eye colouring.
Gait and Movement
Australian Shepherds move with an effortless, smooth gait characterised by long strides that cover ground efficiently. Their legs, front and rear, move straight under the body to maintain a level topline, showing the balance of power and speed essential for herding. Faults in angulation or gait imbalances are penalised in show rings to preserve this functional movement.
