One of my pigs habitually nibbles the humans. Sometimes she is trying to tell us something (usually "I'm done, put me down now!") and sometimes she is just curious and exploratory. We have used some of the piggie whispering tricks in the guide above with some success. We also just don't put her in a lot of situations where she would be tempted to nip (i.e. whereas we will offer our fingers to Leela, our other pig, because she likes to lick/kiss hands, we don't put our fingers deliberately up to Tomie's mouth, because even if she gives us a couple kisses you can bet that a nip is right afterwards.) She's otherwise friendly, not fearful, etc., but she is... overly assertive? She has improved since being a young pig but she's an adult now and I think this is just her baseline personality. She's a bold one.
