I took in a rescue horse, 20-/+ yrs.old, I was told he was a gelding, but the other day I was putting mtg on him(he is the 1 with rain rot) I happened to look down there and he looks like he has testicles, so I reached up and there is something there,I even had my husband take a feel and he too said yeah theres something there.The rescue shelter where he came from said no he is a gelding. Does anyone know what it can be? I will have my vet out in a other 2 weeks for his teeth float and I will ask then, but sometimes I see them and other times I don't.
