This is Charlie, I know the picture is not that great. I board him at a friend's farm and he is the lowest man on the totem poll. I went out today and he had three marks, shown in the picture. One on the lower left is big and deeper than the rest. My best guess are that these are bite wounds, but I don't understand why he didn't walk/run or something! I will admit he does let everyone push him around, but why to this extent? There is more than enough room for him to get away. I literally wanted to cry when I saw him like this. Again, I'm thinking they're bite wounds, but could it possibly be something else. I looked around the barn and pasture, and I doubt anything else could do this but another horse. Is is normal for a bite to be this bad, I have never seen it like this before?
Anyways why I posted here HOW should I treat these? It's winter here and is just cold! Anything I would put on it would freeze and we don't have stalls. I just don't want the wounds to get infected. They are a few days old and I did wash them with an iodine solution and dry them. They have started to scab over now.
Those don't look like horse bite marks which are usually located higher up, neck, back, rump etc. I'd wonder about a dog or dogs or him running into something sharp, broken branches. The symmetry of the two top marks is interesting. This is one of those mysteries that will drive you nuts trying to resolve.
They really don't look like horse bite wounds.. I would look for something in the pasture he could have hit or maybe dogs. I also have one aggressive gelding who has run a very submissive gelding thru the fence. I totally understand. We have since put the submissive gelding by himself in a pasture next to everyone else. Over the fence the aggressive one is friendly.
My suggestion is to wash, wash, wash the wound. Keeping it very clean and run water over it for several minutes at a time will do wonders. Put the vetericyn on it between running water over it.
