SUMMARY:

The aim of this survey is to investigate the interaction between domestic dogs and the forested areas around the Palmares Environmental Protection Area (APA Palmares), a community located in the Atlantic Forest in the State of Rio de Janeiro. The APA area is located at altitudes ranging from 831 to 985 meters above sea level. Dogs were classified into three categories, domiciled, semi-domiciled and stray dogs. It was observed that the domiciled dogs, although kept in fenced yards, come across with some wild animals, which visit the homes, probably looking for food or even shelter as in the case of skunks and hedgehogs. Semi-domiciled and stray dogs frequently visit the forested area located close to the residences, therefore they are in contact with wild animals. According to information from owners, some dogs were treated with ectoparasiticides whenever owners detect infestations by ectoparasites.  Dogs were examined as sentinel animals to diagnose the presence of common parasitic ticks of wild animals. Tick collections took place monthly from January to December, 2019. Overall, 60 (33.9%) positive dogs were diagnosed among 177 examined dogs. Three species of ticks were identified: Rhipicephalus sanguineus, Amblyomma aureolatum and Amblyomma ovale. Overall, 279 adult ticks were collected, distributed as follows: 143 (51.3 %) R.sanguineus, 135 (48.4 %) A. aureolatum and a single female of A. ovale. Tick/dog interaction was evaluated in terms of housing, treatment and host sex using the Chi-square test for R.sanguineus and A. aureolatum. The Chi square result indicated dependence of both species for the housing and sex and independence for the treatment.
