 Terminology as well as identification can be a challenge even for knowledgeable breeders.Standards for horse breeds which do not carry frame or splash spotting patterns, such as the Arabian and Clydesdale, do not consider sabino to be an overo pattern, but sometimes classify sabino horses as roan.To confuse matters further, in Spanish-speaking countries, the term "overo" actually refers to horses with what is called "sabino" in English; meanwhile, in South America, the term "sabino", which literally translated from Spanish means "speckled" or sometimes "roan", refers to a flea-bitten gray.
