A few days ago Ecudo, our 5 year old oberhasli herdsire, stopped eating and was looking off. I started giving him B and C shots twice a day and we moved him to a different pen away from the other bucks. He started to show a little improvement but today mom had dad hold him and she checked his teeth, and she said that all his bottom front teeth are really lose. Does anybody have any idea what would cause this and is there anything we can do for him? He's been getting free choice minerals and hay, and I just started feeding all the bucks grain about two weeks ago for breeding season.
