Diagnosis is not just “does the dog have staph,” because many healthy dogs carry staph. The practical question is whether bacteria are causing disease right now and which medications still work. Cytology (looking at skin cells and bacteria under a microscope) can confirm active infection quickly, while culture and sensitivity testing guides antibiotic choice in recurrent, deep, or non-responsive cases. Rapid clinic-side tests are being developed to support more targeted antimicrobial decisions in canine S. pseudintermedius pyoderma (Pirolo, 2024). This supports antibiotic stewardship and helps avoid unnecessary exposure.
Before the appointment, avoid bathing the dog the night before unless the clinic advises it, because it can wash away surface evidence needed for cytology. Bring clear photos of the first day lesions appeared and any products applied (wipes, sprays, “natural” balms). If the dog has been licking, note whether licking is focused on paws, belly, or one hot spot, because that pattern can point to allergies, pain, or contact irritation. These details help the veterinarian choose the right sampling site and interpret results.
