Blood in Urine!?
So this morning I went out to clean my horses stall. In the past three days two of my horses were in there. Saturday night my pony gelding (Gizmo) ate in there and was let out about three or four hours later. Then my gelding Tiger was put in and let out about noon the next day (Sunday). Nobody went in there Sunday night but then yesterday I fed Tiger in there and let him out a couple hours later. I have been sick the past couple of days so the stall did not get cleaned since the pony went in. So I had the dreadful task of cleaning that wretched stall this morning and to my horror I found some buried bright red shavings! They both do their business in the back of the stall so it was all wet shavings where I found the spots. I have never experienced blood in the urine or poo before so I have no clue what to do. They both are eating, drinking, and walking around fine so they don't seem sick but what could be going on in there? Not sure if it could be Gizmo or Tiger. Tiger is in the stall now so when I clean his stall tonight I will check for more spots. This really scares me, if I find it again we'll call the vet because I'm still not sure if it is blood. Have any of you ever experienced this before?
*Oh, by the way Gizmo hasn't had his sheath cleaned in a while, could that possibly be the problem?
Thanks anyone with advice(:
