Of 33 PCC isolates, nine (27.3%) were meticillin resistant. Multiple drug resistance was identified in 41 of 53 (77.3%) MRS isolates from the VMTH and five of nine from the PCC. The sensitivity and specificity of PCR for the detection of meticillin resistance was 34 of 39 (87%) and 86 of 87 (99%), respectively. Risk factors for meticillin resistance for both sites were antibiotic treatment within the last year (<jats:italic>P<\/jats:italic>\u2003=\u20030.001), and for VMTH, hospitalization of dogs within the last year (<jats:italic>P<\/jats:italic>\u2003=\u20030.001).<\/jats:p><jats:p><jats:bold>Conclusions and clinical importance \u2013\u2002<\/jats:bold> The prevalence of meticillin resistance was not different between VMTH and PCC isolates (<jats:italic>P\u2003<\/jats:italic>=<jats:italic>\u2003<\/jats:italic>0.29).
