Dog (Canis lupus familiaris) — Brachydactyly (hereditary; OMIA-verified species predisposition)
Source: first-hand OMIA (University of Sydney) species-specific hereditary-disorder record, saved verbatim to source_file; every claim below is a C1 byte-substring of it.
Claims
Species: Dog (Canis lupus familiaris)Disorder: BrachydactylySummary: As described by Green (1957), this disorder is "a recessive mutant which reduces the size and function of the outside toes on the front and sometimes the hind feet, with the result that the affected animals are really "two-toed" on those feet".
