Natural Remedies

ok, so my horse is a 3 year old piebald cob and he rubs his head and and his tail pretty much none stop in his stable and when he is tied up. He’s rubbed the top of his tail away and now he has started on his mane. His forelock is gradually getting thinner and thinner.

I coincidently happened after he lost his 5th race could it be he caught ’something’ or stressed out?

and do horses ‘know’ whether or not they won or lost?
