Clinical-epidemiological profile of the canine population in a shelter, Minas Gerais, Brazil, 2019-2020

The aim of this study was to analyze the demographic, clinical, and hematological aspects of the population in a dog shelter located in the municipality of Lavras, Brazil. All animals were microchipped and evaluated by veterinarians. Whole blood samples were obtained from 329 dogs in the months of July-August 2019 and from 310 dogs in the months of January-February 2020. Most of the dogs were of mixed breed, received anti-rabies and polyvalent vaccines (100%), were dewormed (100%), and were spayed/neutered (98.59%), with a predominance of adult (86.51%), short-hair (67.51%), normal body condition (65.57%), medium-size (62.57%), and female (62.36%). The main clinical alterations detected were enlarged lymph nodes (38.69%), skin lesions (31.50%), overweight (23.32%), obesity (6.07%), elevated temperature (17.05%), and ear secretion (15.72%). Regarding hematological alterations, thrombocytopenia (36.31%), leukopenia (15.92%), anemia with decreased hemoglobin values (10.60%), hematocrit (9.70%), and red blood cells (5.14%) were observed. Most of the shelter dogs were apparently healthy, but specific measures for nutritional, dermatological, otological and disease management should be implemented once the health changes are verified, as they impact the general state of the population and adoptions.
