The subject of this discourse is a selectively bred canine, characterized by its compact size, distinctive physical features reminiscent of a specific United Kingdom breed, and a unique coat color resulting from a dilution gene. These animals, while sharing certain characteristics with their larger counterparts, are specifically cultivated to be smaller in stature and possess a recessive gene which gives them a slate grey/blue coat color.
The desirability of these dogs stems from a confluence of factors, including their manageable size, appealing aesthetic, and the perceived rarity of their coloration. Historically, breeds with unique traits have garnered increased attention, leading to selective breeding programs aimed at reinforcing those qualities. This creates both interest from potential owners and potential health risks from concentrated gene pools.
