The Science Behind the Color
Colors & Genetics
From tri to merle, phantom to parti — a quick guide to the coats you'll see in our litters and how genetics shape them.
Traditional Tri
Black, white, and rust — the classic Bernese signature.
Phantom
Solid base with copper points above the eyes and on the legs.
Sable
Warm golden tones with dark-tipped guard hairs.
Merle
Mottled marbled pattern — striking and rare. Every Merle has a unique pattern.
Parti
50%+ white with bold patches of color.
Apricot
Warm cream-to-amber that lightens over time.
Red
Deep, rich rust
Cream
Soft buttery cream — the lightest end of the spectrum.
Chocolate Merle
Marbled Merle patterning but with brown base
Chocolate Tri
Traditional tri color but brown base

The Brown Gene Explained
BB bb Bb
- Curl gene (KRT71): determines how curly vs. wavy the coat will be.
- Furnishings (RSPO2): the gene behind the iconic "doodle beard and brows."
- Merle (M): creates the marbled pattern — bred carefully, never merle × merle.
- Parti & ticking (S, T): control white spotting and color flecks.
