A 12-year-old Quarter Horse refuses to enter a trailer, rearing and striking. Traditional view: Stubbornness or poor training. Intersection approach: Veterinary chiropractic exam and thermal imaging reveal kissing spines (overlapping vertebral spinous processes) in the thoracolumbar region. The horse anticipates pain when jumping up the trailer ramp. Analgesia and targeted physiotherapy resolve the loading issue in 30 days.
