Has anyone ever had any luck with successfully treating urinary calculi in a buck? He gets barely any feed but I found him screaming in pain. Dripping blood tinged pee. I have been giving him ammonium chloride. We have no vets around here so I have googled tons of videos about snipping the pizzle which I did and he was able to empty his bladder. After about 48 hours he went back to screaming In pain and can’t empty his bladder again. Anything else I can do?
