Materials and Methods: Urine samples were collected from 150 dogs suspected of having UTI who were brought to several hospitals in and around Bengaluru via catheterization or cystocentesis. Bacteria were identified in 86 samples based on cultural features, and all isolates were tested for antibiotic sensitivity in vitro.

Results: The study revealed that females are more susceptible (61.3%) to pathogenic infection than males (55.7%) also dogs more than 10 years old are more susceptible (80.49%) followed by 5 to 10 years old group (56.10%), less than 5 years old group (42.86%). E. coli (36.90%) is the most prevalent microorganism followed by Enterococcus (14.29%), Klebsiella spp. (10.71%), Proteus spp. (9.52%), Coagulase negative Staphylococcus aureus (8.33%), Proteus mirabilis (4.76%), Staphylococcus aureus (4.76%), Proteus vulgaris (3.57%), Enterobacter (2.38%), MRSA (2.38%), Pseudomonas aeruginosa (2.38%).

Conclusion: E. coli was the most predominant bacteria isolated from UTI affected in Bengaluru. Dogs of older age are more susceptible to UTI than younger dogs. Female dogs are more susceptible to UTI than male dogs. In vitro sensitivity revealed a significant proportion of bacteria to be resistant to multiple drugs which are commonly used in UTI in dogs.
