Because most people never see farm animals being their most natural selves, people tend to think of them as almost inert. When any animal other than a dog is playful or affectionate, people say, “That cow (or pig, etc.) ‘thinks he’s a dog,’ or is ‘acting like a dog’” The reality is, most farm animals naturally romp, play, nuzzle, think, have best friends and show affection.
