Leaving this for my reference later since I’m binging all Dick’s short stories:

people are getting on a ship on Mars to return to Earth. One of the guys bought a Wub from the natives, described it as a 400lb pig. They wanted to eat it but then it started talking. Apparently it’s an ancient species that can read minds and speak telepathically. The captain wasn’t having it tho so he killed it and ate it. None of the other crewmembers could because it proved to be a gentle sentient being and they couldn’t stomach the thought. Only the captain ate it, then started talking like he was now the wub. 

Very “you are what you eat” vibes. 

Didn’t grip me like Dick’s other short stories.
