Tick-borne diseases are a major threat to both humans and their pets; therefore, it is important to evaluate the prevalence of pathogens carried by ticks on companion animals. In this study, attached and unattached Ixodid ticks were removed from companion animals by a veterinary practice in Hall County, Georgia. DNA was extracted from unengorged adult ticks and each was screened for the presence of  Rickettsia  spp. by polymerase chain reaction (PCR) and sequenced to determine the species present. Two hundred and four adult hard-bodied ticks were identified to species and  Rickettsia  spp. were found in 19.6% ( n  = 38) of the 194 analyzed DNA extracts.  Rickettsia montanensis  was found in  Dermacentor variablis  (14.7%;  n  = 25),  Amblyomma maculatum  (33.3%;  n  = 2), and  Rhipicephalus sanguineus  s.l. ticks (25%;  n  = 4). One  Amblyomma americanum  tick contained  Rickettsia amblyommatis , while  Rickettsia felis  was found in one  Dermacentor variablis  tick, serving as the first report of  Rickettsia felis  in a tick in this region and within this tick vector. This study suggests that there is a risk of companion animals contracting a species of  Rickettsia  from a tick bite in northeastern Georgia, indicating a need for more investigation and highlighting the importance of tick prevention on pets.
