It is important to remember that none of the cephalosporins should be used for the treatment of MRS infections, which are resistant to these antimicrobials. Third-tier antimicrobials (fluoroquinolones) should only be used when in vitro susceptibility is demonstrated and first- and second-tier antimicrobials are not effective.7 The author considers these antimicrobials as last options for treating canine pyoderma, unless they need to be selected for safety reasons for the patient.
