Do dogs feel pleasure? How about crocodiles?  Jonathan Balcombe says yes, they do. And not just dogs and crocodiles, but also fish, monkeys, pigs and chickens.  “Why wouldn’t they?” he says. “Pleasure is nature’s way of saying ‘Good behavior!’ It encourages us to do it again. Little wonder, then, that food, play, sex and friendships feel so good. Fishes line up for a spa service from cleaner-fishes, crocodiles love to bask in the sun, as do chickens, and if you haven’t seen a pig eat a pumpkin then it’s time you turned your lights on.”
