The Australian Cattle Dog, often known as the Blue Heeler or Red Heeler, comes in two primary coat colors:

1. Blue:
   • Solid Blue: This color is a true, even blue without any other color markings.
   • Blue Mottled: This pattern features a mixture of blue and white hairs, creating a speckled or mottled appearance.
   • Blue Speckled: Similar to mottled, but with more distinct and separate specks or spots of blue and white.
   • Blue with Tan Markings: These dogs have tan markings on the legs, chest, throat, jaw, and sometimes above the eyes and on the sides of the face.

1. Red:
   • Solid Red: This color is an even, uniform red throughout the coat.
   • Red Mottled: This pattern involves a mix of red and white hairs, giving a mottled or speckled appearance.
   • Red Speckled: Features distinct spots or specks of red and white.

Both color varieties can have a combination of markings, but the base color will always be either blue or red. These coat patterns are distinctive and help in identifying Australian Cattle Dogs.
