I have written a lot about EOTRH in the incisors and the canines. Look in the posts section. Please go there to read these. There are over 180 images of EOTRH in horses where you can compare what you have in your horse. These are just the incisors. Please check out the pictures for EOTRH in canines here.
Images, if any, for this topic are in a gallery located at the bottom of this page.
