Plain-English summary
A 4-year-old male dog had been suffering from skin problems for three months, including chronic and deep infections that didn't improve with a common antibiotic treatment. After further testing, the vet diagnosed the dog with a specific type of skin infection caused by Streptococcus constellatus. The dog was then treated with a different antibiotic, tetracycline, which successfully cleared up the infection. By the end of the treatment, the dog was healthy and free of any skin issues.

Abstract
This report describes a case of chronic and deep pyodermitis in a 4-year-old male dog with a 3-month skin problems history that had been treated unsuccessfully with fluoroquinolone therapy, prescribed by a private medical veterinary practice, without an early diagnosis. Microbiological examination and antimicrobial susceptibility testing were performed in our laboratory (Faculty of Veterinary Medicine) and a diagnosis of Streptococcus constellatus-associated pyoderma in the dog was made. A new antimicrobial treatment, with tetracyclines, was designed after the definitive diagnosis and antimicrobial susceptibility testing performed by the Kirby-Bauer disc diffusion method. The dog remained free of clinical illness at completion of therapy. To our knowledge, this is the first case of a canine pyoderma caused by S. constellatus, a commensal organism which may also cause pyogenic infections. Furthermore, this study confirms that a fluoroquinolone represents a poor empirical choice for initial therapy of canine pyoderma.
