Horses do this to keep flies away from there faces or any were else flies can get to.
They stand head to tail to help each other swish flies away. They both swing their tails at the other horse's face to discourage flies.
A horse can use its tail to communicate with humans in many ways. For example, when a horse is experiencing pain or discomfort, it tucks its tail in tightly. However, a horse with colic may carry its tail at an unnaturally high angle away from its body. A horse swishes its tail from side to side violently when it is annoyed, whilst a particularly irritated animal may even swish it up and down, When the tail is carried high and the horse is prancing or cantering, it means the horse is in high spirits. General contentment is indicated by a tail in a relaxed state.
The tail head is the base of the horse's tail. It is also called the "dock."
Because it has a tail on one side and a head on the other side, like a penny!
If your horse is going to buck you off chances are that in addition to putting his head down he will pin his ears and he might swish his tail in anger. If your horse puts his head down but in other ways seems relaxed and happy you'er probably fine. Happy Trails!
The side that has the Presidents face on it is the head making the other side the tail.
The head of a penny is obviously the queens head, and the tail is that thing on the other side of the penny.
a coin has a head and tail side
Angry horses often use body language to show they are frustrated or mad. In body language, a mad horse will pin its ears against the back of its head and often show the white part of their eyes and bare their teeth. Occasionally, an angry horse might swish its tail harshly and roughly from side to side (though this may be confused with swishing flies away). However, the sound that an angry horse makes can be a multitude of different things. It might be squealing loudly or heavily snorting. Nonetheless, if you are trying to figure out whether a horse is mad or not, your best bet would be to look at the horse's body language.
Probably to swish things out the way
HE could be upset..or swishing flies away. The best indicator is to look at what position his ears are in. Up for alert or listening, and back for upset or mad.
This is called the mane. The hair that dangles between a horse's ears is called the forelock.
