    B-mode ultrasonography is a widely used imaging technique in small animal practice and serves as a fundamental tool for splenic evaluation, particularly in dogs. However, the lack of standardized parameters for spleen measurement hinders the diagnosis of splenomegaly as well as the differentiation between physiological and pathological conditions. In this context, the present study aimed to establish reference values for splenic size in healthy dogs of different sizes and ages, assessing distinct anatomical regions of the spleen using B-mode ultrasonography. Thirty healthy dogs were examined and allocated into three groups of ten animals each, according to body size, with a mean age of approximately three years and a mean body weight of 13 kg. The animals underwent physical and complementary evaluations, including complete blood count and abdominal ultrasound for measuring the height of the splenic head, body, and tail regions, as well as the diameter of the splenic hilum in longitudinal sec tion. Animals presenting systemic clinical, hematological, or ultrasonographic abnor malities were excluded from the study. The difference in dimensions among the various splenic regions was assessed between size groups, and within each group it was ver ified whether age range exerted any influence. The results demonstrated that spleen size varies according to the animals’ body size, being directly proportional to body weight. Within each group, the body of the spleen exhibited larger measurements com pared to other regions, whereas the tail and head showed no significant differences between them. Additionally, the splenic hilum showed variation according to dog size. No significant influence of age range on splenic dimensions was observed within groups. We conclude that body weight tends to influence spleen size and that B-mode ultrasonography is a safe and effective method for its measurement, contributing to the standardization of splenic assessment in this species
