Overview

Australian Shepherds are a beautiful breed with merle coats, high energy, and an obsession with being close to their families. These dogs are wonderful family companions, but be prepared to keep them active and occupied to avoid having a sad, destructive Aussie.

Australian Shepherds are smart and lovable dogs, but they also demand your time and attention. The most noticeable element of their appearance are their merle (or marble-patterned) coats, but once you get to know an Aussie, you’ll be surprised by their liveliness and loyalty. These dogs have endless energy and need plenty of mental and physical stimulation to keep them occupied. They’re also known to become attached at the hip to their families and often develop separation anxiety. Without enough activity, training, and socialization, you may have a sad and destructive Aussie on your hands. However, if you can keep them entertained and exercised, they’ll be your best friend ‘til the end.

Characteristics

Lifestyle & Living Conditions

Australian Shepherds are great companion for kids and other pets, especially if they’re socialized as puppies. They’re territorial by nature and may be shy around strangers, but deep down, they’re affectionate and kind. Aussies get easily bored and need to have people around them. Without enough exercise or socialization, they may develop separation anxiety or become destructive. These dogs can be happy in warm or cool climates, but they need plenty of space to run and play and should have their primary living space indoors.

Exercise & Activity

Aussies need a lot of high-energy activities and mental stimulation to keep them happy. They’re the perfect exercise buddies, especially for families that like being outdoors. Take your Australian Shepherd for a run, hike, or a long play session in a big backyard to keep their hearts soaring and their minds sharp.

Temperament and Behavior

Australian Shepherds are smart, loyal, and eager to learn. They have lively personalities and are known to behave like puppies well into adulthood. Aussies are hopelessly devoted to their owners and bond closely with their families. However, they’re also prone to developing separation anxiety, so be sure to balance togetherness with alone time so your Aussie doesn’t get too attached.

Coat & Grooming

The Australian Shepherd has a dense undercoat and outer coat with medium to long hair that’s straight or slightly wavy. Aussies’ fur is short and soft on their head and legs, with a thick mane around the neck. These dogs can be black, red, red merle (dark patches on a light background), or blue merle, and some may have white markings or tan points too. Although their hair is long, Australian Shepherds don’t need much grooming. Give them a thorough brushing (especially during shedding season), and only bathe them after a good romp in the mud.
