When we talk about the color of fur, it is very important that the description of color in the dog breed standard also includes other aspects, such as the color of eyes, eyes, nose, lips and nails. In addition, when we say coat color, we mean acceptable color, because there are many other colors besides acceptable color, and only two colors are involved in the dog breed standard.
They are: qualified color and unqualified color. Different from other dog breed standards, the French bulldog breed standard does not mention the unpopular color, and several preferred colors and defective colors all come down to acceptable colors. So it is very certain that the coat color of French bulldogs is either acceptable or unqualified.
