Horse handlers are people who work with horses and are responsible for their care and handling. GROOMS, which is a 6 letter word, are responsible for the daily care of horses, such as feeding, grooming, and exercising them. Ostlers, which is a 7 letter word, are responsible for the stabling and care of horses, such as providing food, water, and bedding. Both GROOMS and ostlers are important members of the horse handling team, ensuring that horses are healthy and well cared for.
