Yes, one of our vets suggested that but they need us to keep an eye on him so he still has to come in for at least 10hrs per day.. when we got him he was so kind and gentle, now if you walk past his door he will try to bite you. I've got a few bites, mainly aquired from just taking his rugs off. He also kicked the barrow so hard it cracked. See how much pain he is in for it to have changed him so much?! Going down to Newmarket and hopefully they will find some more answers! They did find a possibility, something called Trigeminal Neuralgia (the nerve behind the poll, I think?!)
