Many dogs suffer from subclinical cervicothoracic (CT) pain without displaying overt clinical signs. On close examination, restricted motion of the CT junction region can be found in affected dogs. The restricted CT junction motion and subclinical pain result in reduced performance in agility trials, hunting activities, lure coursing, conformation classes and other athletic activities in which dogs participate as well as reduce their overall quality of life. In Traditional Chinese Veterinary Medicine (TCVM), pain is due to local Qi/Blood stagnation. Si-zhen (The four diagnostic methods) in TCVM especially Wen-zhen (Inquiry), Wang-zhen (Observation) and Qie-zhen (Palpation) offer helpful information to diagnose Qi/Blood stagnation of the CT region and determine the severity. A grading system of CT Qi/Blood stagnation is useful to determine the best treatments and a grading algorithm is outlined. The TCVM treatments of acupuncture, Chinese herbal therapy and Tui-na can effectively treat both subclinical and overt CT pain, but vary with the grade of CT Qi/Blood stagnation.
