Solid black is excluded from the French Bulldog breed standard, which is a source of persistent confusion because a great many black-looking French Bulldogs are perfectly acceptable brindles.
Is it black or is it dense brindle?
A brindle dog with very heavy striping can appear solid black to casual inspection. Examine the coat in strong daylight, particularly along the flanks and the rear legs, and faint lighter striping is usually visible in a dense brindle. A genuinely a/a black dog shows none anywhere.
This distinction has practical consequences: a dense brindle is a recognised colour and can be shown, while a true solid black cannot. It also affects what a breeder can honestly charge, since 'rare black' pricing applied to a standard brindle is straightforwardly mis-selling.
No health implications
Unlike dilution and merle, recessive black carries no associated health risk whatsoever. Its exclusion from the standard is convention, not welfare.

Common questions
Are black French Bulldogs Kennel Club recognised?
Solid black is not accepted in the breed standard. However, densely striped brindles that appear black are recognised — and a considerable proportion of dogs sold as 'black' fall into that category.
Are black French Bulldogs unhealthy?
No. Recessive black carries no colour-linked health risk, in contrast to dilution or merle. The general breed health concerns apply as they do to any French Bulldog.
