Without peer as a cattle herder, the Australian Cattle Dog is ready and willing to work all day. Their agility, strength and courageousness allow them to easily control and move cattle in both open and confined spaces. Stubborn cows don't discourage this dog – they just become more determined to get the job done! The breed can be blue or red (can be in mottled or speckled pattern), with or without black, blue or tan markings.
