StudMatch — Litter Color Prediction Tool

Enter your dam's coat color genetics and instantly see which studs are a compatible genetic match — with predicted litter color probabilities for each pairing.

How It Works

StudMatch uses the standard canine color genetics model to calculate expected offspring probabilities based on the sire and dam's E locus, B locus, K locus, A locus, and merle gene status. Select your dam's genetics, browse studs, and see predicted litter outcomes before you commit to a breeding.

Genetics Loci Covered

• E locus — controls red/yellow vs. black pigment expression
• B locus — chocolate/liver dilution
• K locus — dominant black vs. agouti/brindle
• A locus — sable, tri-color (tan points), fawn, and recessive black
• M locus — merle pattern (single merle vs. non-merle)
