To be completely honest... I am really starting to doubt a lot of this bay/brown questions. I think most horses show a bit of softening or colour around the muzzle in their winter coat... I don't have a bay horse, but every one I can think of does. My chestnut horse does, even. I don't think a little lightening of the muzzle in a winter coat alone a brown horse makes. Does anyone agree with me at all? There has to be more than that, otherwise every horse I know is brown, and bay is rare. Which I cannot accept.
