The last couple of days my horse has been tossing his head alot, yesterday he caught me in the chin and I was lucky to still be standing. This has never been a problem with him and its not due to his halter or his bridle because he does it all the time. I noticed a couple sores on his nose which I'm sure are from hom testing the new electric fence. He also has some small scabs in his ears. Could one or both of these things be causing him to toss his head like this? What could the scabs in his ears be and what can I do to clear them up? Any ideas or advice please and thank you?!
