Popis: Abstract Background Urine cultures are frequently recommended to rule out infection as a postrenal cause of proteinuria. Objective Identify characteristics associated with bacterial growth in urine in proteinuric dogs. Animals Four hundred and fifty‐one dogs admitted to a teaching hospital between January 2008 and January 2018 with urine protein‐to‐creatinine ratios (UPCs) >0.5. Methods Retrospective study included dogs with a UPC, urinalysis, and quantitative urine culture (QUC) performed within a 72‐hour period by searching electronic records. Dogs with recent antimicrobial therapy, urine collected by methods other than cystocentesis, or UPC ≤0.5 were excluded. Signalment, comorbidities, serum BUN and creatinine concentrations, urinalysis findings, and QUC results were recorded. The association between these characteristics and presence of bacterial growth in urine was assessed by univariable and multivariable analysis. Results Thirty of four hundred fifty‐one dogs (6.7%) had bacterial growth in urine. Of these, 18 (60.0%) had active urine sediment. Bacterial growth in urine was associated with pyuria (odd ratio [OR] 25.1, 95% confidence interval [CI] 7.9‐79.6, P
