I noticed my arabian horse has a bump on his belly, it is about 3'' round and protudes about half a inch.Does not bother him at all.I had someone come look at it (a vet tech) and she thinks its a strained muscle, it is attached to the abdomel (sp?)wall and softens up the more its touched,or its also possible my paint horse kicked him.I noticed the bump about 2-3 days ago and it has gotten a little bigger.Has anyone ever had this happen to your horse? What do I do, anything?? I'm calling the vet tomorrow(he also needs his teeth floated) to make a appointment.Also a week in a half ago I rode him hard, lots of running, cause he didnt want to stop.lol Could that have anything to do with it?? Thanks
