What does his 'starey' coat mean?

You need more than one sign of illness to make an ill horse generally. There is a saying that no horse looks good at blackberry time, this is what you are most likely seeing now.

If he was not eating or drinking or had other signs of listlessness, then that might be a warning of something.
 
My pony is "tuffting up" now for winter, he looks really weird with the summer coat and spiky bits coming through. He has already got his winter beard. Cant wait till he is fluffy and warm to cuddle again in winter.
