The designation refers to a smaller variant of a recognized dog breed, exhibiting a specific coat color. This particular type shares the characteristic physical traits of its larger counterpart but in a more compact size, and possesses a coat that appears bluish-gray due to a recessive gene affecting pigmentation. For instance, a dog labeled as such would have the distinctive wrinkled face and stout build associated with its breed, but at a reduced height and weight, and with a noticeably unique coat coloring.
Interest in these animals often stems from a desire for a smaller companion with the familiar traits of a well-loved breed. Their size can be advantageous for owners living in smaller spaces or who prefer a less physically demanding pet. Historically, breeders have selectively bred for size and color, leading to the emergence of this specific type. This selective breeding, while appealing to some, necessitates a careful consideration of potential health issues that can arise from manipulated genetics.
