Do horses go through teething???? I think my boy is growing in his big boy teeth... He hasn't been good with me putting on his headstall.. so I checked his teeth and there was some blood by his right front tooth. It seemed like they're getting longer. Around Novemeber when I bought him I remember he had his cute little baby teeth still. So I'm guessing he is in pain from them growing? Anything I should do to make it less painful?
