About the Australian Koolie
The Australian Koolie is a versatile, high-stamina working dog that has been a staple of Australian rural life for nearly two centuries. Unlike many breeds refined for the show ring, the Koolie has been primarily selected for its utility, resulting in a dog that is exceptionally hardy, agile, and capable of working in the diverse and often harsh Australian climate. They are known for their 'natural' working style, utilizing a combination of heading, heeling, and backing sheep, making them invaluable to stockmen across the country. Physically, they are lean and athletic, with a build that prioritizes endurance and speed over bulk. In a domestic setting, the Koolie is a devoted companion, often forming a deep bond with one person. They are incredibly sharp-witted and require a home that understands the needs of a working breed. Without a 'job'—whether that be competitive agility, obedience, or farm work—they can become bored and inventive. However, for an active owner, the Koolie offers an unparalleled level of partnership and intelligence, always eager to learn and ready for the next challenge.
Breed Standard
Key characteristics from the breed standard
In the ring, the Koolie displays a functional, balanced silhouette that screams 'work-ready' athleticism. Their movement is effortless and ground-covering, characterized by a smooth, tireless gait that suggests they could run for hours without fatigue. Their structure is sound and lithe, with a keen, intelligent expression in their almond-shaped eyes that often captures a judge's attention.
In Australia
The Koolie was developed in Australia in the 19th century, having been bred from imported British herding dogs, specifically ancestors of the modern smooth-coated Collie, as noted by the Koolie Club of Australia. According to the Working Koolie Association of Australia Inc., the breed's development likely included the German Tiger, a European herding dog. These dogs were brought to South Australia by German immigrants arriving in the mid-19th century.

Things to Consider
Every breed has its quirks — here's what to know
The Australian Koolie is an elite athlete, which means their energy levels are significant; without adequate daily exercise and mental 'work,' they can become restless. Because they are a herding breed, they have a high prey drive and may chase moving objects like cars or bikes—this is a predisposition, not a certainty, but secure fencing is a must. They are also more likely to be sensitive to certain medications due to the MDR1 gene, so owners should always consult a vet before administering new treatments. Some Koolies can be prone to hip and elbow dysplasia, so keeping them at a lean, healthy weight with a fresh food diet is a great way to support their joints. Some merle-patterned Koolies may be susceptible to hearing or vision impairments if not bred responsibly; however, a well-bred Koolie is one of the hardiest dogs you will ever meet. They can be vocal if they feel there is work to be done, but they are generally focused and quiet when their needs are met.
Feeding Guide for Your Australian Koolie
Healthy Weight
15-24 kg
Daily Feeding Amount (general starting estimate)
450-700 grams
Adult Koolies should be fed a high-quality fresh diet consisting of approximately 2-3% of their ideal body weight daily. For an average 20kg Koolie, this equates to 400-600 grams per day, split into two meals. Active working dogs may require up to 4% of their body weight.
Feeding quantities are general starting estimates only. Individual needs vary with body condition, weight trends, age, health and activity. Ingredient percentages alone do not guarantee complete and balanced nutrition — consult a veterinarian for individualised dietary guidance.
Ingredient percentages alone do not guarantee complete and balanced nutrition. Seek veterinary or qualified canine nutrition guidance for individualised dietary advice. Raw feeding, specific proteins or fresh foods should not be presented as preventing, treating or managing breed health conditions without veterinary diagnosis and supervision.
Majestik's Recommended Feeding Approach
Breed Diet Notes
A high-protein, nutrient-dense fresh or raw food diet is ideal to support their high metabolic rate and working muscle mass.
A Koolie thrives on a diet rich in lean proteins such as Kangaroo, which is native to their Australian heritage and provides high protein with low fat. Majestik's Beef or Lamb blends are also excellent for sustaining their high energy levels. Adding seasonal greens and omega-3 fatty acids from fish can support joint health and coat shine, which is vital for a breed prone to high physical impact.
These are general breed-level notes only. The appropriate food and serving amount depend on the individual dog's age, health, body condition, activity and tolerance.
