Because R. rickettsii infects vascular endothelial cells, the resulting vasculitis can cause a range of clinical signs depending on where the infection develops and how disseminated it is. Dogs with RMSF typically present with a fever (102°F to 105°F) approximately 4 to 7 days after exposure.
Rickettsia bacteria are the cause of several infections, including ehrlichiosis, and Rocky Mountain spotted fever in canines. Ticks are absolutely the most common vectors of the bacteria for dogs, with three species being the most prevalent. Rickettsial infections may lead to severe clinic signs if allowed to progress to the chronic stage.

Zoonotic Risk of Rocky Mountain Spotted Fever in Dogs. R rickettsii is considered a zoonotic pathogen. The potential for household clustering and large urban outbreaks, particularly in areas with transmission by brown dog ticks, makes RMSF a disease of significant public health concern.

Nov 9, 2020 · There are more than 25 species of tick-borne, spotted-fever group Rickettsia species worldwide, with R. rickettsii being one of the most virulent and dangerous. For dogs, R. rickettsii is the only known spotted fever group Rickettsia that causes clinical disease in North America.
Following infection with R. rickettsii, the duration of rickettsemia in dogs is brief, approximately 5–14 days. Therefore, infected dogs do not play an important reservoir role, and pose a minimal zoonotic threat to humans.
