Angry, upset, or irritated.
When a horse's ears are pinned back (Flat against the back of it's head.) it is telling you "Back off buddy!" It means the horse is not in a good mood. (It is not happy.) This could be followed by a kick or a bite, so watch out and back up!
Well if the horses ears are just slanted backwards a little it means the horse is listening to you. but if the horses ears are all the back where they are touching the back of there neck then they are very mad.
when a horse puts his ears back he is angry or in pain. It depends what he puts his ears back at. I hope this is of some help to you. what to you do that he puts his ears back at...?if you wright back im sure i can help you..=]
Sorry, had to delete the answer in front of mine. I have been around horses for 12 years. I would know. When they are slanted backwards, he is paying attention to you, and is relaxed. When pinned back, flat against the head it is VERY mad, BACK OFF. When perked forward, it sees something, or is in a high strung mood. When you first approach a friendly horse, no doubtingly it will have its ears forward.
If a horse's ears are back, it can indicate anger, pain, or unhappiness; however often horses tilt their ears back to listen to a noise behind them. If the ears are pinned back flat to the head, it is a sign of anger, pain, or unhappiness.
This could mean many things. It could mean the horse feels bad, or is in a bad mood, or it could be getting ready to 'herd' you or even attack.
A hamster will move its ears back when it feels threatened or is scared. This is one way of determining the mood of your hamster.
Horses swivel their ears for many reasons. It might be putting the ears back from stubbornness. It might be putting them back because it is mad. Of course, it could also just be listening to something behind it!
What are his body signs? Is his ears laid back, or pricked forward? Does he appear tense or relaxed? Is the only horse you have? Did you call out to him before you entered the pasture or not? Did you have a feed bucket or hay bale on you at all? And, how long have you had him? It's most likely that he's just happy to see you and is running up to greet you, or thinks/sees you have a treat for him that he is super-eager to get from you. If he's happy to see you, his ears will be pricked up and not laid back, he will not show the whites of his eyes like he's scared or challenging you (unless he's an appaloosa, which they always show the whites of their eyes no matter what mood their in), or appear tense. If his ears are laid back, he could either be in a bad mood, afraid of you, or scared you might hurt him and have learned to strike first. But, if he's a good nature horse (which I'm sure he is), then he'll just either be eager to get that yummy thing in your hand to eat, or he's just really happy to see you.
The way the horses ears are depends on its mood. They might be a little nervous or cautious.
It may flatten it's ears against it's neck, show the whites of it's eyes, swing it's rear towards you( this is a sign that it is going to kick), or swish it's tail.
If you want to know . then horses will pull their ears back and slightly lean forwards they might be in a very angry mood they might also have angry eyes in a way of saying they are very deep. horses do tend to create anger among other horses by pushing or shoving. THERE IVE ANSWERED UR QUESTION!
