I think people are genuinely trying to help Isiwizzy but every time advice is given, we get a little more information which then proves the advice incorrect or out of sync. You posted about your horse kicking your little sister and being bad tempered and grumpy in the winter. You also said you'd had him for 6 years and he had always been 'grumpy'. People gave advice about what they thought could be the problem and then you tell us that your mum is a vet and your dad is a farrier. You then tell us that your parents run a horse training school after a few more posts and that your mum is your instructor. It causes a lot of confusion as people are not quite sure what sort of advice it is you actually need. Its better if you are up front and honest about your real situation as people here really care about each other and we do take notice of anything which sounds potentially dangerous. The situation you were describing about your horse sounded really dangerous. None of the other forum members knows your horse so we can only go by what you tell us. What you were describing was a horse that was going bad. Now you're telling us he's not really that bad because we don't know him like you do. People really don't like to think they have been wasting their time getting concerned and trying to be helpful. I think the best advice I can give you is to get him checked over by your mum and dad if he is still giving you problems as your parents know you and your horse best and I am sure if you had a bad horse, your parents would have told you its time for him to move onto someone with a bit more experience in his type of behaviour. If you need more advice then you have to be really specific so that people don't think you are wasting their time. Have a lovely christmas and I am sure things will work out for you and your horse.
