So recently I took in my boyfriend's horse because the horse was not living in a sanatery enviornment. I've notice this horse seems sore on his hindend, I believed it was a sore muscle or hip out. However recently I discovered a cut or a slit in his frog. Its not deep inside, but its long as in I can put the hoof pick inside (the pick part) and all the way to the curve in the pick. I am worried about infections. Is there anything I should do? Any tips?
Thanks in advance
