It depends on the situation the horse is in. If the horses ears are swiviling back and forth and moving around alot they are more than likely just listening to sounds, other horses or you.
If their ears are pinned back against their head and their teeth are bared (like a dog snarling) then they are upset or angry. Their tail may also swish around if they are angry. Horses pin their ears back as a warning to other horses or things they feel are a threat.
It depends on what you mean by slanted. Do you mean pinned back against their head or just slightly back? If their ears are pinned right to their head it is a sign of aggression it doesn't mean that the horse will kick or bite you however you should keep a close eye on what that horse is doing also that is one way a horse tells another to back off is by laying their eats back.
This usually indicates that the horse is unhappy or upset, or that he is in pain. If the ears are continually moving and slant back one at a time, he may be listening to you while you're riding. Take care if the horse's ears are pinned to the back of his head, as he is extremely upset.
if the horses ears are slanted backwards it mean they might be unsure of angry
it is angry or ticked off.
Well if a horses ears are laid back, that means a horse feels scared or threatened.
If a horse's ears are pointed backwards, they may be listening to you if you are riding. It can also be an expression of disapproval or annoyance.
angry
if a horse's ears are back slightly, it means he is irratated or restless if his ears are back completely, he is fearful,angry, aggressive, scared ect. hope this helps!!
depends... it could mean it's angry and going to bite. Some horses ears are naturally back. sometimes they're smelling... Theres a few possible answers.
That it is angry!
He/She is relaxed.
If a horses ears are just slanted back hes either listening or annoyed. If they're pressed back then hes pissed.
It indicates that they are annoyed When their ears are slanted backwards they are also likely to bite so be careful because they can really hurt you.
If they are slanted back or lying flat against the head it indicates that the horse is unhappy/uncomfortable. There may be another horse too close to it whom it doesn't like.If a horses' ears are like this be careful because it is perhaps an early sign that the horse is going to kick or bite.
