Jesus also gave a PSA about pigs and dogs:
"Give not that which is holy unto the dogs, neither cast ye your pearls before swine, lest they trample them under their feet, and turn again and rend you."
(Matthew 7:6 KJV)
He is talking about people.... Men that act like pigs or dogs are dangerous. So beware of sharing the word of God with them, because they will get angry and turn against you. Rather, give the words of life to those who will receive them. God will show you who.
