Hi, I have one Boar piggie right now and he is probably about 3 and 1/2 months old right now. He loves to be held, snuggled, brushed, and he absolutely loves his floor time! When holding him, more like letting him lay on my chest, while I'm petting him he will every once in a while nip at my fingers. He has never full on bit me or shown any aggression other then the nipping. Is there anyway to stop this or will he grow out of it? Anything helps! Thank you!
