This report presents a case of deep pyoderma in a 5-year-old dog presented with widespread skin lesions, anorexia, and poor general condition. Microbiological examination of skin scrapings isolated Staphylococcus pseudintermedius. The isolate was determined to be susceptible to amoxicillin-clavulanic acid, enrofloxacin, erythromicin, gentamicin, lincomycin, cefoperazone, rifamicin, cefoxitin, kanamycin, cefotaxime and trimethoprim-sulfamethoxazole, and resistant to oxytetracycline, vancomycin and doxycycline. Although initial treatment with amoxicillin-clavulanic acid based on the antibiogram showed temporary improvement, symptoms recurred; the subsequent combination of enrofloxacin and trimethoprim-sulfamethoxazole was ineffective. Due to the progressive deterioration of the patient's general condition, euthanasia was performed. The failure to achieve the expected clinical response despite using susceptible antibiotics was attributed to the chronicity of the disease, the widespread nature of the lesions, the patient's dehydration, and a weakened immune system limiting antibiotic efficacy.
