My Horse came lame in one front leg a week ago, it was sudden and no explanation, no heat, swelling or obvious signs. i had his body/joins checked and he was gave the all clear so this lead too me knowing he was foot sore. he has very deep colataral grooves and hot feet around coronary band. All 4 hooves are giving me the same signs... and are all warm and deep... but he is only lame in 1? feet have no obvious smells, maybe a little odour but same in all 4 week. some days he is looking less lame than others, im suspecting stone bruise or abcess? has anyone had anything like this befor? thankyou.
