Abstrakt: Platelets are fundamental cytoplasmic fragments involved in hemostatic processes. Alterations in platelet counts are commonly reported in canine medical clinics. We performed a retrospective analysis of the causes of platelet count alterations in a large cohort of dogs in the semiarid northeastern area of Brazil between January 2017 and December 2019. In a retrospective study, 14,694 medical and laboratory records were evaluated to describe the main etiologies associated with thrombocytosis and thrombocytopenia in canines according to the climatic season in the semiarid region of northeastern Brazil. Platelet data and variables of sex, age, and diagnosis were compiled. A total of 3,208 (21.83%) dogs had alterations in platelet count (APC), of which 3016 (20.52%) had thrombocytopenia and 192 (1.31%) had thrombocytosis. A predominance of female dogs (53.96%) and dogs aged between 1 and 8 years (43.86%) was observed. Animals with hemoparasitosis had a significantly lower chance (P < 0.05) of thrombocytosis, differing from dogs with gastroenteritis and parvovirus infection, which had a significantly higher chance (P < 0.05) of thrombocytosis. Furthermore, animals had a significant chance (P < 0.05) of presenting with APC in the rainy months. The prevalence of platelet count alterations detected in dogs with infectious/parasitic and neoplastic diseases of high incidence in semi-arid northeastern Brazil serves to create awareness among veterinarians regarding the additional care that must be implemented for canines. In addition, greater attention must be paid to platelet count alterations in cases of infectious/parasitic diseases, especially in the months with the highest rainfall. [ABSTRACT FROM AUTHOR]
