White is one of the accepted colorations of the French bulldog, acknowledged by the AKC. However, an all-white or extreme white Frenchie, in which 90% of the coat coloration is white, is rare or uncommon.
Most white French bulldogs have a pied pattern coming in brindle and white, fawn and white, white and brindle, white and fawn, cream and white, or fawn brindle and white, also recognized as standard variations of white by the AKC.
One of the leading causes of the coloration in an entirely white French bulldog could be the ‘Albino’ locus, a particular gene variety restricting pigmenting in certain parts of the body. This thus leads to an all-white body with pinkish skin, eyes, and nose.
White dogs often suffer from deafness as the cilia (small hairs in the inner ear) remains undeveloped as the pigmentation is incomplete. An individual study has noted that about 25% of the all-white Frenchie puppies suffer from bilateral deafness (inability to hear in both ears). In comparison, about 38% could be unilaterally deaf (facing hearing issues in a single ear only). They could even be more susceptible to burns and other skin problems.
They could cost between $1500 and 3000, however, if going for the all-white ones, that are a little rare too, a lot can go in their maintenance mostly due to the increased amount of health problem they suffer from.
