I'm not sure if this is even the correct place to categorize this, but here I go anyway ...
I was just finishing up a lesson with my leaser's daughter and she always brings a treat to give to the horse. She is very timid when feeding, and always pulls away long before the horse can take the treat. I'm meticulous about the "flat fingers and thumb" rule, and I often assist by holding her hand out, protecting her fingers.
Now my boy is normally very well mannered, patient and all lip. I'd never so much as felt even a corner of his teeth graze me when giving treats. However, while I was helping the girl out the other day, he purposefully took several snaps at my hands, and managed to bite one of my fingers fairly hard.
Thank god he missed the little girl, however my finger was not so lucky. I am missing the entire nail (he cracked it in half, and both halves have since fallen off), and it hurts like nothing I've ever felt. I can't put any pressure on the pad of my finger (it hurts like hell, and it gushes blood when I do so). Anybody have any advice on treating it? I've been cleaning it with warm water and have been applying antiseptic to it. I keep it wrapped most of the time, but have begun to allow it to breathe for small periods of time during the day.
After he bit me, he got a couple good wallops and seemed to return to his normal, chilled disposition. After wrapping up my finger, several people (including myself, as best I could) checked him over. He seemed to be fine.
I went out yesterday and he was perfect. I hopped on and rode around bareback with just a halter. I checked him over (still nothing), and decided to hand fed him to see if he'd try to pull the same crap, and he was the perfect gentleman.
I've put a sign up on his stall "Please do not hand feed" and have asked everyone not to give him anything either.
I'm not sure what to think of this incident, is it something to brush off and say "that's horses for you", or should I be really concerned?
