Well, I finall got round to buying the large dog harness, and strong lead.
On it went (just! If he gets any bigger we'll have to re-think!) and Murphy came out for his first proper walk. Not counting the time he and a friend escaped and frightened the life out of the cat when they wandered around the back of th chicken shed! We could still pick them up then.
Anyway, we wandered out into the big wide world to my cries of "Pig, pig, pig, come on, good boy!" and Murphy decided exactly when and where he wanted to stop and root for worms!
So still abit of training to go, but he was a good pig and returned home safely, with some oat based bibery.
Poor Geraldine, the goat kid he shares his home with was most put put out, as the big goat goes out on a lead for milking, now Murphy's been out, and she just gets to watch them go and cry her goaty noises after them!
