In terriers, “gameness” means tenacity, especially during the hunt for small animals.  A very game dog will rush into potentially dangerous situations in pursuit of their prey, for example, down a rabbit hole. Gameness can also refer to the tendency for a terrier to keep fighting despite being injured or risking injury.
A dog’s gameness is tested as a part of their temperament during earthdog or Barn Hunt trials; it is not considered to be a learnt set of behaviors.  However, some breeds and lines of dogs have been selected for their gameness during fights; these are called “gamebred”.
