Well, and just to set the record strait, Ducnan is an exceptional little pony (in my biased opinion). He doesn't nip or kick or even mouth on my arm or hand if he thinks I have something he wants. He's very curious and inquisitive about what I'm holding, but he's never bitten me out of aggression or for want of something.
He's been an absolute joy to have in my life, and I'm going to give him treats as a reward from my hand because I think it's just a matter of teaching him not to nip-- you nip, no treat. I was just wondering if it was a baby phase (he's almost a year old though). Thanks for all the input!!
