Aw poor boy, I'm glad it didn't need stitches, it should heal pretty quickly
Mine have picked up a few minor barbed wire injuries while working, I hate the stuff
Tilly ran right through a low strand a few years ago and got a small tear in her chest and Rodaidh got snaffled on a twisted piece hanging off a fence as he was jumping through it but they were both ok, tbh neither of them really noticed it at the time! I tore my trousers climbing over a 3-strand fence on a shoot last year
