To confirm arthritis in dogs, veterinarians typically employ a combination of diagnostic techniques. Physical examinations allow vets to detect pain, swelling, or decreased range of motion in joints. Radiographs (X-rays) are crucial for visualizing joint degeneration and other changes associated with arthritis. Blood tests can assess overall health and rule out other diseases that may mimic arthritic symptoms. In some cases, advanced imaging such as MRI or CT scans may be used to obtain a more detailed view of the affected joints.
