Queensland Heelers AKA Australian Cattle Dog, (blue Heeler, red Heeler Dingo and more.) come is a variety of colors and sizes. there are 4 main base colors black, Red, Chocolate and blue/gray. (see photo #2 in the slide show of nose colors) the nose and toe nails tell the true color of the dog. Heelers are born white then in a few weeks they color out into a base color of one of the 4 base colors in patters of speckled mottled and roan which can vary a great deal. the base color black makes the common blue of the breed the black speckling mixed with the white in different patterns makes a variety of blue shades the nose is always black. the other base colors work the same way for making the different shades and patterns. common Red Heelers have a black nose and usually have some black hairs through the red but not always, some reds are true red with black nose and only red and white mixed hair. Mating blue to blue should produce blue unless there are recessive genes hidden in the back ground. Silver/blue is just a certain blending of common blue, the mix of black and white hair usually more white than black, a light pastel form that appears as Silver. A blue or Silver dog with black nose can produce blue pups from any color mate. A common red dog with black nose can produce red pups from any color mate. mating a blue dog to a red dog can sometimes produce red/blue mix when the gens are equally matched both colors appear in the dog through the entire coat this is sometimes referred to as Purple, nose is black. Chocolate, Slate/blue and Fawn are recessive and can only be produced if both parents have that color gene in the background. these colors can carry for many generations before showing up when the right 2 dogs are mated that allow the colors genetics to double and appear. When this happens unexpectedly it can be a real surprise. If you are wanting to produce these rare colors both parents have to carry the gene for the color you are wanting to produce. It is best to have both parents have the recessive colors within 2 or 3 generations. Chocolate ( Liver Brown) is the inability to be black so turns out brown from very dark just a shade off of black to a light cream just a shade off of White. in all chocolates the nose is brown and is darker or lighter to match the coat. toenails are also brown. Chocolate to Chocolate produces all chocolate puppies, two blue dogs who each have a chocolate parent will usually have 1/3 chocolate 2/3 blue pups. A chocolate parent and blue parent who had a chocolate parent usually have about 50% chocolate 50% blue pups. same ratio holds with red mated to chocolate. if there is a red parent and blue parent each having chocolate genetics there is usually all 3 colors of pups in the litter. Slate/blue (AKA steel gray, gun metal blue, pearl and probably other) is the dilute of black and the same ratio holds true except that it is not a good idea to mate two slat/blue parents together for it can produce a skin problem with hair loss. so to produce slate blue let the color come from common blue with slate recessive in both parents. Fawn ( Isabella ) is the dilute of Chocolate and should be produced the same way as Slate Blue. White is usually also a double recessive but can upon occasion come from a single white parent it is the failure to tick out meaning to speckle or to color out.
