While an Australian Cattle Dog generally works silently, it will bark in alarm or to attract attention. It has a distinctive intense, high-pitched bark. Barking can be a sign of boredom or frustration, although research has shown that pet dogs increase their vocalisation when raised in a noisy environment. It responds well to familiar dogs, but when multiple dogs are present, establishing a pecking order can trigger aggression. It is not a breed that lives in a pack with other dogs.
