What is a dilute Aussie?

Answered by Robert Flynn

A dilute Aussie, also known as a Maltese dilution or MLPH, refers to a specific gene that affects the color of the dog’s coat. This gene is recessive, meaning that both parents must carry it in order for it to be expressed in their offspring. It primarily acts on black and liver hair, while tan points remain unaffected.

When a dog with the dilution gene is black, their coat color is transformed into a slate blue shade, resembling that of a blue Doberman. This change in color can be quite striking and unique, giving the dog a distinct appearance. On the other hand, if the dog is red, the dilution gene causes the coat color to become a beige shade, similar to that of a Weimaraner.

It’s worth noting that the dilution gene only affects the color of the hair and has no impact on the overall health or temperament of the dog. Therefore, a dilute Aussie is essentially the same as any other Australian Shepherd in terms of breed characteristics and behavior.

The prevalence of the dilution gene in Aussies is relatively common, and it is considered one of the most widespread mismarks in the breed. Mismark refers to a deviation from the breed’s standard coloration, which in the case of dilution, alters the expected coat color.

As an owner or breeder of Australian Shepherds, it is important to be aware of the dilution gene and its potential impact on the appearance of the puppies. If both parents carry the dilution gene, there is a chance that some of their offspring may inherit the dilute coat color. However, if only one parent carries the gene, the puppies will not exhibit the dilution.

Understanding the dilution gene can help breeders make informed decisions when planning litters and ensure that potential owners are aware of the possibility of dilute coat colors in their future Aussie companions. It is also crucial to educate potential owners about the fact that the dilution gene does not affect the dog’s health or temperament in any way.

A dilute Aussie, or an Australian Shepherd with the Maltese dilution gene, refers to a dog whose coat color has been altered due to the presence of this recessive gene. Black-coated dogs become slate blue, while red-coated dogs become beige. Despite the change in coat color, the dilution gene has no impact on the dog’s health or temperament.
