Pre-Articular and Explosive form of Rheumetoid Arthritis in a Mongel Dog

A case of an active-explosive form of Rheumatoid arthritis with poly-arthritis was presented in a mongrel male dog. The same was brought six months back with a pre-articular/ subclinical form with predominate signs of anemia but no lameness. On the basis of its past and present history, clinical examination and hematology, it was diagnosed as a case of flare of active and explosive form of Rheumatoid arthritis. Its etiology, pathology, management and treatment with DMARDs and corticosteroids were discussed.
