A horse with its tongue sticking out of its mouth, and seemingly unable to get it back into its mouth, is a rare thing. This could result from actual swelling of the tongue, due to ingestion of an irritating compound or toxin, or a traumatic injury to the tongue.

Weakness or paralysis of the tongue may also result from neurologic dysfunction at the level of the brainstem, or the nerves that control the muscles of the tongue. Horses with botulism can present this way, and immediate treatment is vital. Horses with severe infections of the mouth, head and tongue itself may also not be able to retract their tongues.

Horses that are severely debilitated can also show this sign. Strength of the tongue muscles is an indicator of general muscle strength. Old horses that have lost their front (incisor) teeth tend to stick their tongue out between their lips.

WHAT TO DO

Assess your horse’s general health using the Whole Horse Exam (WHE) paying particular attention to attitude and appetite, rectal temperature. Walk the horse in circles to each direction to assess its movement. Assess their mouth (wear gloves) looking for any other abnormalities.

WHAT YOUR VET DOES

Your vet assesses the mouth and tongue itself to determine the nature of the problem. They assess general health, especially the neurologic system, and look for other signs of neurologic disease that might relate.
