In my opinion, yes. Because after season 1 all animals are left on the island. They’re dying because of starvation (inside homes and barns or because they find no food on the island). In that way dogs are basically forced to attack humans many times in lack of hunger. It’s so sad and hard to watch for me.
Yes, in episode 2 of season 2, around 26:30-27:20 three dead cats that died of starving are seen lying on the floor in a house entry after people got the door open. It’s very graphic. Skip it.
