Yawning and Head Shake
If you notce your
horse is shaking their head or yawning there may be a TMJ (jaw joint) or
upper cervical subluxation, especially if your vet has not found any
tooth or gum issues.
The TMJ will regulate jaw
movement and the muscles as well as the upper cervical joints interact
with this movement. Your horse may be attempting to unlock the jaw and
or decrease tension in the upper cervical region. When riding you may
notice resistance to the bit and head tossing.
Teeth that needed to be floated or arthritis within the joint can cause this condition not to mention improper tack.
A animal chiropractic evaluation can determine if this issue is present.
