When a horse shakes his head, it can be worrying and frustrating for both horse and rider. Research suggests that some horses can experience hyper-sensitivity of facial nerves, and although the exact causes are still unclear, it seems there may be environmental triggers or a chemical instability that causes this, causing mild, irritated tingling through to severe shooting pains like an electric shock for your horse.
What signs would my horse show that he is experiencing discomfort?
Affected horses may show some of the following signs:
- Uncontrolled and sometimes violent upwards movements of the head
- Nostril clamping
- Striking out at the face
- Rubbing the nose / face
As this behaviour is associated with pain, and is typically a progressive issue, it is advisable to contact your vet if you suspect your horse is experiencing nerve sensitivity. However, as yet a cure has not been found, most owners of horses that shake their heads choose to look at how best to manage the affected horse.
It is important to know what your horse’s triggers are and try to limit their exposure to them. For example, for many limiting their exposure to sunlight can be very important which can mean stabling during the day and/or use of a UV blocking face mask when turned out and riding.
Additionally, targeted nutritional support can be very beneficial. Magnesium plays several extremely important roles in nerve health and function, and particularly in the regulation of neuroexcitation.
Can I feed anything to support my horse?
Shakergard from Equine America was formulated to provide two different sources of magnesium, including the amino acid chelate which is thought to have a very high bioavailability. It also provides a number of antioxidants, and plant-based support to anti-inflammatory processes, as well as key vitamins and phytochemicals to help with facial discomfort caused by seasonal allergies as well as nerve dysfunction.
