Sixty‐five dogs with a positive urine culture and CKD were recruited, representing a total of 70 isolates. Most common isolates were Escherichia coli (67% of isolates) and coagulase negative Staphylococci (9% of isolates). Among all isolates, 11% were susceptible to all tested antimicrobials, 54% were MDR, 19% were possible XDR and 3% were resistant to all tested antimicrobials. Escherichia coli was susceptible to all tested antimicrobials in 15% of cases, MDR in 53% of cases, possible XDR in 13% of cases and none was resistant to all drug tested. For Escherichia coli, percent in‐vitro susceptibility was 96% for fluoroquinolones, 89% for sulfamethoxazole‐trimethoprim and extended‐spectrum cephalosporins, 80% for aminoglycosides, 64% for tetracyclines and penicillins + beta‐lactamase inhibitors, 43% for penicillins, 38% for non‐extended spectrum cephalosporins and 32% for polymyxins.
