The origin of the Border Collie dog breed can be traced back to around 300 years ago. They originate from the Anglo-Scottish border region – which separates Scotland and England.
The Merle Gene
The term “merle” refers to the diluted nature of the eye-catching coat color that leaves striking streaks, splotches, and patches – giving off a ‘bluish’ appearance.
Much like other Border Collies, the blue merle Border Collie is a pup with unique coat colors. They boast a white chest and blue or grey-colored fur on their back, tail, ears, and face.
Personality and Temperament
Their coat color does not influence their behavior. When it comes to their personality, all patterns and colors of the Border Collie breed have the same good-natured traits.
Blue merle Border Collies are as sweet as they appear to be. They are very affectionate, loyal, and loving. These precious pups make excellent family companions.
