Which brush keeps the dense blue coat neat without over-fluffing the plush texture?

For a dense blue coat that’s plush-like a Russian Blue or British Shorthair-skip the slicker brush. That’s for fluffing out undercoats, which will ruin the smooth, velvety finish. Instead, use a fine-toothed metal flea comb or a rubber grooming mitt. The comb glides through without lifting the topcoat too much, and the mitt picks up loose hair while polishing the surface. Brush gently in the direction of growth, not against it, and focus on a few minutes daily rather than one long session. That keeps shedding under control without turning the coat into a fuzzy mess.

A soft bristle brush, like one with natural boar bristles, is your best bet. The bristles are firm enough to work through the dense coat and remove loose hairs, but they don’t lift and separate the topcoat the way a slicker brush does. That plush texture stays smooth and compact, not puffy. Just brush in the direction the fur naturally lies-short, gentle strokes.
