Ok well I'm not totally new to horses but I am new to ownership. I bought my horse last year as a 4 year old. Everyone thought I was mad but hes given me so much joy and he is so sweet natured and calm. He is bombproof on hacks and just loves to please! Well this was up until a month ago! My horse has lived out all summer and has now changed into his winter routine , where he is stabled at night and brought into the field in the day. Since this has happened he has gone wild! He is a nightmare in the school, he just wants to gallop everywhere and out hacking he wants to jump and buck . he has lost his manners, he pushes me and drags me. Is this normal when they have been brought into a winter routine? What can I do to get him back to his normal calm self?!
