The shoulder joint is a very complex area whose anatomical structure is different than the other joints of the appendicular skeleton. Lameness associated with the shoulder can be a diagnostic challenge when working on athletic dogs. Most of these problems may not be observed in the general canine pet population. Because of the close relationship between the handler and the canine athlete, slight joint abnormalities are identified. The cause of these low grade and subclinical lameness’s are minimally understood by the general veterinary community. It is not the purpose of this article to discuss the well-known orthopedic problems associated with the shoulder but to address the obscure and subclinical issues that are related to soundness of the shoulder area.
