Hog-dog rodeo or Hog-dogging is spectator event that simulates wild or feral boar hunting with dogs. It requires specially trained and bred "hog dogs" that are used to bay and sometimes catch a hog or boar. In most cases, bay dogs psychologically control the pig and there is no physical contact. In some cases, however, such as Uncle Earl's Hog Dog Trials, along with bay dog events, catch dog events are included. In these, specially bred and equipped dogs catch and hold the hog by the ears before the animals are quickly separated by a person who hog-ties the pig.
