Service dog trainers teach guide dogs, hearing dogs and therapy dogs to assist people with disabilities. Apprentice trainers typically work at service dog training schools under the supervision of experienced instructors and, with experience, may go on to instruct other trainers. This is a physically demanding position, which requires trainers to walk and control dogs of various sizes and breeds.
Barley is a food ingredient used in soups, stews and breads. This major cereal grain is a component for health foods and is used to ferment malt beer. A member of the grass family, barley also serves as animal fodder. In 2014, global sales from barley exports by country amounted to US$7.8 billion.
Barley is a common staple in human and animal diets. Part of the grass family, it grows in over 100 countries and is one of the most popular cereal crops, surpassed only by wheat, corn and rice. Although barley is fairly adaptable and can be grown in many regions, it is a tender grain and care must be taken in all stages of its growth and harvest.
