His teeth are being floated, and it probably wont hurt him that bad maybe not at all but id still like to give him a warm soft treat when he gets it done. This will only be his second or third time (he is fairly young and he didnt have his teeth done with his first owner) and the first time it hurt him so bad he was drooling like crazy and he didnt want to eat (he doesnt get that bad any more poor thing) umm... if anyone was wondering I looked into bran mash and eqqus (the magazine) said exactly what you said, its not good to feed a horse a lot of bran mash, but it said that on occasions its fine. I may and may not give it to him, im looking at both sides b/c I find this interesting, I never thought of it this way! Like I said, thanks for bringing this up!
