Care and upkeep

The Australian Cattle Dog requires daily exercise, and it enjoys long hikes or jogs coupled with vigorous games. It excels in herding activities and can compete successfully in dog sports such as agility, obedience, tracking, lure coursing, dock diving (in which a dog leaps off a platform into the water to retrieve an object), disc catching, and nose work.

The Australian Cattle Dog’s coat is thick but requires only occasional brushing to remove dead hairs, which are fairly abundant during the breed’s two shedding seasons (fall and spring). Australian Cattle Dogs are prone to hip dysplasia, and puppies should eat a large-breed puppy food designed to slow the dog’s growth rate in order to reduce the chance of developing the condition. Some people mistakenly believe that the typical roan coat color (a coat whose main color is mixed with white hairs) is a type of merle pattern (that is, a marbling effect that occurs when dark patches are set against a lighter background of the same color), but it is not. Unlike merles, roans can be bred to one another with no fear of producing health-compromised double-merle offspring.

Temperament

The Australian Cattle Dog is a tough and rugged breed. It is intelligent and learns very quickly, but it is equally independent and often headstrong. It is a high-energy dog that enjoys both physical and mental challenges. The Australian Cattle Dog requires a firm hand. While the breed is a perfect companion for an adventurous active person, it is often too energetic and strong-willed for young children or seniors unless the dog is well trained. Although the Australian Cattle Dog is playful and affectionate with family members and pets, it can be suspicious of strangers and may be aggressive toward strange dogs. It is an excellent watchdog and protection dog.

These are well established and widely accepted generalizations about the breed. Individual dogs may differ in behavior and temperament.
