Blue Merle English Bulldog – Everything You Need To Know

Blue Merle English Bulldog Breed Overview

Blue Merle English Dogs are merle Bulldogs with grey speckles on their coats. Even though the speckles are grey, they are called blue merle dogs, and the marking can sometimes either be patches of tan or black.  Merle is just the change in color of the coat, eyes, and nose because of genetic mutation.  The mutation is purely physical and doesn’t change the temperament of the blue merle English Bulldogs. They are genetically identical to the English Bulldogs except for pigmentation.
