So dry bandage and call the vet. Thanks. My farrier did trim him a few weeks ago, I wasn't present and he has a new assistant (maybe something went wrong there). He always has a slight limp for he has an old injury on his other back leg making him walk weird overall. On top of this this injured leg is majorly toed in so he always walks weird on it anyway and to add onto that he has really bad arthritis so needless to say when we saw him miss stepping a few weeks ago we did not think too much of it for that is normal for him, he is never not miss stepping. This week he started walking worse which grabbed our attention that something else could be going on now as well. When I cleaned his hooves these few weeks I did not notice the bruising due to all the dirt covering it, only after hosing it down today did I see this. Poor old man, it was already hard walking, now to add this onto it all. Thanks for the help I will do as you advised.
