It looks a little swollen but then again We don't know what he looks like normally it could be a bean.. My horse was swollen and he would kick at his belly and it was cause he had a bean
Heres what a bean is and a pic as to where is would be located What is "smegma"? Smegma is a collection of dirt and excretions, builds up inside the sheath and must be removed for the sake of the horse's health. It is not the most pleasant thing to do, but it is essential. If you don't or can't do this, you should have your veterinarian clean your horse's sheath at least every 6 months.
What is a "bean"? A firm lump of smegma that has collected and hardened inside the horse's penis. This lump or "bean" must be removed as often as possible. It can cause serious pain to your horse. There have been thousands cases in the last year where the bean is overlooked by the owner and becomes so large that the horse can no longer urinate...which may also cause other problems due to blockage. healthSheathCleaning.gif
