Can you please remember when typing a reply to other members that there are children on this website. I'm not siding with anyone, and everyone is entitled to their opinion, but when you do write a post, can you please make sure that it is not in any way accusatory, rude or offensive etc...
However I do have to say J R lover, I do disagree with you a little. There are some breeds calmer than others, and there are some breeds more high spirited than others. This isn't stereotyping, but a fact.
Although I do agree that more often than not a horses temperament will depend on how they have been trained and brought up, their breeding does play a large role.
