A mule.
Donkeys have long ears, considerably longer than horses Horses are faster than donkeys. Even smaller horses can outrun a donkey. Donkey's conformation is not as similar as a horse when you look into the finer details. Donkey's need an earlier warning so they can have a head start to run away. Therefore donkeys hearing is better.
It's not true that rabbits with long ears have a longer lifespan than rabbits with short ears. Ear length has no bearing on a rabbit's lifespan.
It is simply the nature of the individual species of animal. I am speaking here of "average" lifespan for that particular animal. For a horse, it is 22-25 years. For an elephant, about 60 years. For a dog, 12-14 years.
it is animal are more got better hearing then human
Animals may have smaller ears because they live in cold environments and heat is lost through your ears
The donkey is a domesticated hoofed mammal, which is related to the horse. But a Donkey is smaller than a horse with long ears, short hair on the tail, a short mane, and a dark stripe along the back. A Mule is a hybrid animal from crossing a jack (male donkey) and a mare (female horse).
Mule. Cross between a horse and donkey. This animal is sterile. It also has a donkey's shaggier coat, upright mane and long ears and its legs are more compact than a horses (less slanted). However it has the horse's intelligent face and eyes, the horse's sleek barrel and usually the horse's hard hooves.
Forelocks are the small sections of hair that fall over the forehead on some animals, particularly horses. They are usually longer than the rest of the hair on the head and can be styled or trimmed for practical or aesthetic purposes.

So they reach food, that is not eaten by animals with a shorter neck. It's an adaptation where an animal with a longer neck is more likely to survive and produce offspring than a animal with a shorter neck. Survival of the fitness.
Their actual ears should be just slightly longer than their nose, but the fur could grow a little bit longer but not much. so feel free to cut it :)
No longer than female horses.
