* Bulldogs are known for having a variety of colors, including white, red, fawn, brindle, and piebald.
* A black mask is a common trait in many bulldog breeds, including the English Bulldog, French Bulldog, and American Bulldog.
It's important to note that:
* Color descriptions like "buckskin" are not standardized in bulldog breeds.
* The best way to determine a bulldog's color is to consult a breed standard or speak to a veterinarian or experienced breeder.
If you're interested in a specific color or combination of colors, it's best to research breeders who specialize in that particular variety.
