A bay dog (or bailer, in Australian English) is a dog that is specially trained to find, chase, and then bay, or howl, at a safe distance from large animals during a hunt, such as during a wild boar hunt. Bay dogs chase and circle the boar, keeping it cornered in one place, while barking intensely. This behavior is known as "baying" or keeping the boar "at bay". In Australia the terms "bay dogs" and "baying" are not in common usage; these are colloquially referred to as "bailers" and "bailing", respectively.
