Yesteday i thought my mare was limping, but then she seemed ok so i assumed i just imagined it, anyway today me and my dad both noticed it, and on the right front leg. i picked and scrubbed her front hooves (both just incase my judgement was wrong) but saw nothing, felt up and down her legs and shoulder and no lumps bumps or swelling. I wondered if with the snow, her snowshoes could have bruised the sole? or is there something else that it could possibly be?
