I was walking by Hayden and noticed blood marks all over the floor around him and looked him over and noticed that some of his pad looks like it was skinned off. sorta like a stubbed toe I guess, but on his pad. Anyway, I took a cold wet cloth and held it to stop the bleeding, but not sure if I should put anything on it? It doesn't seem to bother him (he's not limping or anything). Any suggestions?
