Human friends may come and go, but a horse could be one of your mostloyal, long-term friends if you treat it right.

　　Horses understand words better than expected, since horses can hearthe human voice better than even dogs can, due to their particular range ofhearing. And scientists predict that trainers could have greater success ifthey use more verbal commands in their horse training programs.

　　Horses possess excellent memories, which allow horses to not onlyrecall their human friends after a long period of separation but also toremember some complex human instructions for ten years or more. The bonds withhumans are likely an extension of horse behavior in the wild, since horsesvalue their own horse relatives and friends, and are also open to new,non-threatening acquaintances. Horses maintain long-term bonds with severalmembers of their family group, but they also interact temporarily with membersof other groups when forming herds.
