Bacterial growth was found in 6/15 voided urine samples, and in 2/15 clean voided ones. All cystocentesis samples were culture negative. There was bacterial growth in 11/15 ejaculates, and a positive correlation between age and bacterial growth was detected (rs = 0.78, p = 0.006). Five of these dogs had negative cultures from all their urine samples. For 10/11 dogs with positive ejaculate cultures, similar culture results were obtained from the lavage‐fluid. Seven dogs examined with ultrasound had changes compatible with benign prostatic hyperplasia; six of these had positive ejaculate cultures. The bacteria grown from the different samples (urine, ejaculates, lavage‐fluid) were: Pasteurella spp., Mycoplasma canis, Staphylococcus pseudintermedius, Prevotella sp. Gram‐negative anaerobic rods, Streptococcus canis, Coagulase‐negative Staphylococcus spp. and mixed floras consisting of the ones mentioned.
