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.
Typically, very few individual ticks (eg, 1% of Dermacentor spp ticks) carry R rickettsii, even in areas considered highly endemic. However, in highly enzootic regions of Arizona where R rickettsii is transmitted by the brown dog tick, as many as 5% of ticks may be infected.
In dogs, the signs of RMSF can be vague and non-specific. Typically, a dog that has become infected may have one or more of the following clinical signs: poor appetite, muscle or joint pain, fever, coughing, abdominal pain, vomiting, diarrhea, swelling of the face or legs, or depression.

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.
Rocky Mountain spotted fever is a disease of humans and dogs that is caused by Rickettsia rickettsii. (Rickettsiae are a specialized type of bacteria that live only inside other cells.)
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.
