Rocky Mountain spotted fever caused by Rickettsia rickettsii is a potentially fatal tick-borne disease in dogs requiring rapid diagnosis and antibiotic treatment to prevent serious welfare impact.
RMSF causes rapid and severe systemic illness in dogs with significant pain, fever, and neurological disturbance. The disease can progress to vasculitis, organ failure, and death within days without appropriate treatment. Welfare-focused management requires rapid clinical recognition and empirical antibiotic therapy when RMSF is clinically suspected. Tick prevention is the most effective welfare protection. Dogs in endemic areas with sudden unexplained fever and thrombocytopenia should receive immediate doxycycline therapy pending results.
