A limer, or lymer /ˈlaɪmər/, was a kind of dog, a scenthound, used on a leash in medieval times to find large game before it was hunted down by the pack. It was sometimes known as a lyam hound/dog or lime-hound, from the Middle English word lyam, meaning 'leash'. The French cognate limier has sometimes been used for the dogs in English as well. The type is not to be confused with the bandog, which was also a dog controlled by a leash, typically a chain, but was a watchdog or guard dog.
