But more often when there are new horses around as they're establishing a pecking order of sorts. Sometimes it resolves itself (usually) sometimes the aggressor needs to be removed until the less dominant horse feels more comfortable in the new pasture... Eventually with the reintroduction of the aggressor horse as the new guy on the block so the pecking order can be re-established. Sometimes nothing will work and they just need to be separated -shrugs- each horse has a mind of it's own. The aggressor might associates you with food so in his mind the best way to ensure he gets the most food is if he makes the other horse back off.
ok thanks my first horse is a gentle sole so it is weird seeing him go after the new horse we have to be careful though because the new horse has very sore feet but I know my first horse will get over it thanks for your help
