7. Fire

Definitely, horses are afraid of fire because they know it can cause danger to them. Commonly, a scared horse will run away from danger. However, it may be different with the fire scenario as horses may stubbornly stay at their stable to feel safe.

No one would feel blissful if a fire is burning stables of horses. Even you would be afraid and panic, thinking of you and your horses’ safety. Just like your reaction, your horse will certainly be dreadful and anxious. Your horse will not only be afraid of fire and smoke alone. It will also be scared of the environment, the wind and the noise around.

Unreasonable as it may be, your horses will run back to their stalls in fiery stables.

What is the reason behind this irrational decision?

The simple explanation is that your horses identify their stalls as the safest place for them, especially if they are stabled on a regular basis. Their stalls are their safe home since their food is there; likewise, these are their space for resting.

The smoke, running people, loud sirens and all other noises are highly alerting the flight instinct of horses. They know they need to escape from the chaotic scene. By escaping they need to feel secured, which they can only find in their stalls.

8. Water

Horses are afraid of water because they could not recognize its depth; by instinct, they must stay dry as they aim to protect their legs at all times from indefinite path.

Encountering a puddle or small body of water is highly expected if you are doing trail rides with your horse. It is very common for a horse to become scared, not wanting to cross or even take a step on that swift stream, if it is its first time and not yet trained to do so.

Not being acclimated with water will definitely make your horse turn away as it doesn’t know what is waiting once a step forward has been made. Your horse has no idea whether it will be taking easy leaps or fatal ones just to cross a stream.

Each time you ask your horses to cross water, you are putting lots of pressure and questions to them. The best thing you should do is to make sure you build solid trust with your horses; then, introduce them to water, train them slowly, repeat the process and never rush or push them to their limits.

9. Firework

Horses are afraid of fireworks because of the flashing bright lights and deafening blasts.

Horses are not the only animals that can get easily startled by loud noises. The flashes with thunder-like sounds can be usually seen and heard during holidays and events. As an owner, you must be worried about your horses’ reactions once the periods for celebrations are coming.

Even the calmest horse will get terrified once it hears fireworks. The noise will bring so much stress and anxiety to your horse so it is important to be prepared beforehand to help it cope up.

Various behaviors that are associated with anxiety such as perspiring, galloping and quivering can be observed when your horse sees and hears fireworks. Your horse might even break through their stalls due to agitation.  Injuries such as strains and sprains might also occur as your horse’s behavior can get extreme with continuous fireworks blasts.

10. Human

Instinctively, horses can be afraid of humans if they just meet them since they are unacquainted and no trust has been formed yet.

Being a prey animal, a horse will always have its guard up high and ready to flee anytime if it feels danger. As a human, you must prove that you bring no harm and are ready to build a lasting relationship.

If a horse perceived you as a threat, its next actions can be unpredictable that may even cause dangers to you. Even if the first approach of self-preservation of horses is running away, they are still wild horses inside that have a capacity to hurt or even kill humans.

It is important that you, as an owner or trainer, know how to properly communicate and build trust with your horses. There are positive human actions that might have negative meanings to horses’ perspectives.

You might not realize that the more you bring yourself closer to your horse, the more it rejects your approach as the actions you used are against its natural instinct of safety, making them more confused and scared.
