Free-roaming dogs are removed from the street by the Municipal Animal Control division/shelter and NGOs to safeguard public health as well as to prevent any suffering dogs may face and to find them homes. However, adoption rates are low and there is a lack of public programs aimed at humane control causing increased numbers of street dogs and overcrowding in shelters, compromising health and welfare. We aimed to evaluate the health of dogs from municipal shelters and independent shelters, and community dogs in the city of Guarapuava through clinical examination and complete blood cell count tests. The main changes found in the clinical examination of 297 dogs were hyperthermia in 4.0%, tachypnea in 20.5%, ocular and oral mucosa hypocorada in 6.4%, and ectoparasite infestation in 42.7%. Changes found in the erythrogram were anemia in 15.1% and polycythemia in 3.4%. In the platelet count, thrombocytopenia was found in 10.1% and thrombocytosis in 10.4%. On the leukogram, leukocytosis was observed in 14.8% and leukopenia in 3%. The results reveal the compromised health of some animals, requiring better diagnostic investigation, since certain clinical and complete blood cell count alterations may be caused by zoonotic agents that can endanger human and animal health.
