Blue Merle French Bulldogs- Everything you need to know

Blue Merle French Bulldogs are grasping the attention of many pet owners because of their captivating beauty. They are specifically bred to gain a pattern of hair patches and pigment on different parts of their body (e.g., nose, eyes, paws, etc.).

This specific pattern is obtained by modifying a “Merle gene”. These genes remove pigment in the parts of the body mentioned above. If the same pigment removal occurs in the iris, it is known as the Blue Merle French Bulldog.

They were first produced in the early 2000s and they have been one of the most sought-after breeds since.   

Do Merle French Bulldogs have permanent blue eyes?

Blue eyes of dogs have always been in trend and always attract pet owners. Many Frenchie bulldogs possess blue eyes when they are young, but as they grow older, the color of their eyes changes.
