Why do horses drool a lot?

Horses don't actually drool a lot in a typical sense. While they might have a little bit of saliva around their mouths, excessive drooling, also known as ptyalism, is usually a sign of a problem and can be caused by a variety of factors:

Dental Issues:

* Tooth Abscesses: Infection in the teeth can cause pain and inflammation, leading to excessive salivation.

* Dental Malocclusion: Misaligned teeth can make chewing difficult and painful, resulting in increased drooling.

* Sharp Points: Sharp edges on teeth can irritate the gums and tongue, causing increased saliva production.

Other Medical Conditions:

* Gastrointestinal Issues: Ulcers, gastritis, and other stomach problems can cause excessive drooling.

* Neurological Issues: Certain neurological disorders can affect the nerves controlling saliva production.

* Poisoning: Some plants and toxins can cause increased saliva production.

* Stress or Anxiety: Horses can drool more when they are stressed or anxious.

Normal Salivation:

* Eating: Horses produce a lot of saliva to help them chew and swallow their food. This is normal and not a cause for concern.

If you notice your horse drooling excessively, it's important to consult with a veterinarian to determine the underlying cause and receive appropriate treatment.
