In Taft v. Taft, 209 Ga.

Bulls are more dangerous than cows and steers; stallions are more dangerous than mares or geldings; rams are more dangerous than ewes and lambs. However, these animals have been kept for stud purposes from time immemorial so that the particular danger involved in their dangerous tendencies has become a normal incident of civilized life. The virility which makes them dangerous is necessary for their usefulness in performing their function in the socially essential breeding of livestock, and justifies the risk involved in their keeping. Therefore the law has not regarded bulls, stallions and rams as being abnormally dangerous animals. Id. at 500 (1).
