Not only will we chat about muscles here, but we’ll be discussing the whole horse. Let’s talk about the TMJ (temporomandibular joint) and why it matters.
The TMJ connects the lower jaw to the skull and allows your horse to chew, swallow, and comfortably move their jaw. Because the jaw is connected to muscles throughout the head and neck, discomfort in this area may influence a horse’s comfort, posture, and way of moving.
Your horse may show signs that something isn’t quite right, such as difficulty accepting the headstall or bit, changes in eating habits, head shaking, unusual resistance, or other changes in behavior or performance. These signs don’t always mean the TMJ is the cause, but they can be a reason to look deeper.
Supporting your horse’s comfort starts with regular dental care, a balanced diet, proper tack fit, and paying attention to changes in their normal behavior.
Because at the end of the day, nobody knows your horse quite like you do.
