Plain-English summary
A study found that many dogs with skin infections called superficial pyoderma had a type of bacteria known as methicillin-resistant Staphylococcus pseudintermedius (MRSP) both in their noses and on their skin. Out of the dogs tested, a significant number had MRSP in both locations, indicating that the bacteria can be present in the nose even when the dog has a skin infection. This suggests that pet owners should be aware of the risk of antibiotic-resistant bacteria in their dogs, especially if they have skin issues. It's important to discuss any concerns with your veterinarian, who can recommend appropriate treatments.

Abstract
Currently, antimicrobial-resistant staphylococci, particularly methicillin-resistant Staphylococcus pseudintermedius (MRSP), are frequently isolated from canine superficial pyoderma in Japan. However, little is known regarding the nasal prevalence of MRSP in pet dogs. Here, we determined the prevalence of antimicrobial-resistant staphylococci in nares and affected sites of pet dogs with superficial pyoderma. Of the 125 nares and 108 affected sites of pet dogs with superficial pyoderma, 107 (13 species) and 110 (eight species) staphylococci strains, respectively, were isolated. The isolation rate of S. pseudintermedius from pyoderma sites (82/110 strains, 74.5%) was significantly higher than that from nares (57/107 strains, 53.3%) (P<0.01). Notably, the prevalence of MRSP (18/57 strains, 31.6%) in nares was equivalent to that in pyoderma sites (28/82 strains, 34.1%). Furthermore, the phenotypes and genotypes of antimicrobial resistance in MRSP strains from nares were similar to those from pyoderma sites. Our findings revealed that the prevalence of antimicrobial-resistant staphylococci in the nares of pet dogs with superficial pyoderma is the same level as that in affected sites. Therefore, considerable attention should be paid to the antimicrobial resistance of commensal staphylococci in companion animals.
