Speaking of blood, when I was at the barn feeding yesteray afternoon, I noticed that my older gelding, Tennessee, had blood in his sheath. At first I thought it was just smegma, but when I touched it, there was blood too. Not alot, but still troubling. He's had problems before with smegma buildup and swelling of the sheath but it's always gone away with a good cleaning and some Nitrofurazone ointment. He's not swollen now, so I don't know what it could be. I don't know if he's got blood in his urine or not coz I never see him pee. It kinda worries me so I'm taking a half day off today to take him to the vets. All I need is another patient to doctor!
Strange.... but could be something as easy as an insect bite - don't you have them blood drawin' bugs down there?
For your sake, I sure hope not.
