The city dog population is estimated at 82 000 and identification of tick species and infestation prevalence on this host has not been determined. A major infectious disease of dogs in the city, canine ehrlichiosis, is transmitted by Rhipicephalus sanguineus ticks. At the same time, autochthonous leishmaniosis has been recently described in the city and a role for dog ticks in the disease transmission has been supposed in Brazil. In this work, we present general information on dog ticks in Uberlândia municipality and region. Dogs from 33 farms and 31 districts were examined for ticks from July 2007 to February 2009. On the whole, 413 dogs were examined, 311 (75.3%) from the city and 102 (24.6%) from rural area. Overall infestation rate of dogs from Uberlândia was 37.3% and the mean infestation intensity was 3.25 parasites per dog. In the urban area, 100 dogs (32.2%) had ticks whereas 54 dogs (52.9%) from rural areas were infested. Four tick species were found: Rhipicephalus sanguineus, Amblyomma cajennense, Amblyomma ovale and Boophilus microplus. In the city, only R. sanguineus and one A. cajennense was found on dogs and R. sanguineus and A. ovale were the main dog ticks in rural areas.
