In veterinary medicine, diseases restricted to the gallbladder (GB) are uncommon in dogs. Among the diseases that affect dogs and are more prevalent are cholecystitis, GB mucocele, cholelithiasis and neoplasms. Histopathological examination of GB is indicated as the gold standard. However, abdominal ultrasound examination is increasingly being performed in veterinary clinics and constitutes a safe, low-invasive, harmless and low-cost examination. It allows cases of GB disorders that were previously underdiagnosed to have a more accurate diagnosis. In this context, the objective of this study was to identify, quantify and correlate the different GB lesions of dogs diagnosed by ultrasound and histopathological exams. The GB of 60 cadavers of dogs admitted to the Veterinary Pathology Sector of the Veterinary School of the Federal University of Minas Gerais (EV-UFMG) were evaluated, with no predilection for sex, age and race. The results demonstrated that the ultrasound examination, when correlated with the histopathological examination, showed 83% agreement in the analysis of the general data for the presence or absence of GB changes. The level of agreement in the Kappa test was 0.63, which is considered a substantial value. In comparison, Kappa's agreement in the conditions studied individually obtained a low correlation. Correlating the data from the non-parametric analyzes and those from the histopathological exam, 35% of the samples presented with a GB mucocele, 33.3% did not present any type of alteration and 30% were diagnosed with cystic mucinous hyperplasia (CMH). The similarities between the ultrasound findings of different GB disorders – such as CMH, mucocele and cholecystitis - indicate that the ultrasound examination does not present a good diagnostic accuracy. However, further studies should be carried out in order to deepen the understanding of the correlation between ultrasound and histopathology to guide diagnostic conclusions
