An issue that can occur, however when fed dry is that if it is fed to a horse that tends to eat treats/food quickly it will expand as it goes down the throat & may cause suffocation if not taken care of.
A similar thing happened to a friend's horse when her bf's mother unknowingly fed him beet pulp pellets. He started choking & having troubles with his breathing so they took him to the vet. By the time they got there he had begun to come back around but they still had the vet flush his throat out.
This isn't very common, but it does happen if the horse doesnt chew his food properly.
^^ What she said.
I have fed beet pulp for years, dry and wet, without any problems. Now, I do have two horses that will choke on dry pellets of ANY kind because they eat too fast, and one gets nervous during feeding time if there is any horses being moved around before he's done (which makes choking worse). They get their food wet, and I use alfalfa hay pellets, which do not expand very much. The water in their food seems to slow them down a bit and makes going down easier.
So, choking is only a concern IF your horse is already prone to choke on pelleted feed.
