my lurcher lamed itself last nite after clipping a large bit of rubble with its back leg whilst runing a bunny (which he caught:) [bANNED TEXT] he got back he was fine i noticed a little cut but it didnt seem to bother him,But when i went to walk him this morn he was in agony and the wound seems to of opened quite a bit more,looks like a trip to the vets, ive washed the wound with salty water and just layed him up to rest is there anything else i can do??????????
