Can't tell 100% will be able to see when hes shedded / clipped but I think its lacing. Which is a marking. My mare has it. I love horses with lacing I think it looks super cool. If you research it don't believe the "its believed to come from a fungus" cause thats not true lol
thanks for the replies! i've never heard of lacing before - interesting.... i do believe the coloring is only on the tips of the hair, but i will check again tomorrow. Nope, Marsha, when i brush him, the pattern stays the same. i can't wait to clip him - won't me long now! i do hope to see some dapples under that hair - and maybe some lacing!
