My colt is a brown and usually looks dark bay in the winter and bay in the summer. Today I went out to see him (I only get to go once a week) and his coat just looks terrible. Blonde all throughout his mane and tail and his coat kind of has a yellowish tinge to it. His mane and tail already had some lighter hairs throughout but not this bad.
It has been very humid with highs of 90 degrees and lots of rain so maybe that's a contributing factor. Could it be that he is just sun bleached or could this be caused by a mineral deficiency or something else he is lacking?
I wasn't able to get any pics today but here are some of how he normally looks. First in August 2013, Second November 2013, third May 2014
