How often should you bathe a french bulldog?

The folds, the tail pocket, and where the smell actually comes from.

Those face wrinkles, the neck folds, and the hidden pocket under the tail stub all do the same thing: they trap moisture, skin oil, and food debris in a warm dark crease. Yeast loves exactly those conditions, and yeast is the musty, corn-chip, sour smell that frenchie owners complain about. It is not a dirty coat. A frenchie can have a spotless coat and still smell, because the problem lives inside the folds where a normal bath never reaches.

The routine that works has two halves. Folds must be cleaned, wiped through with a damp cloth until nothing more comes off, and then dried bone-dry, every single fold, every single time. A cleaned fold left damp is worse than one never touched, because you just watered the yeast. Between full baths, a weekly wipe-down of the face folds, neck folds, and tail pocket keeps the creases from ever building up to a smell.
