Diagnosis
-
For surface pyodermas, a clinical exam is usually sufficient for diagnosis; however, for recurrent or deep pyodermas your veterinarian may perform skin scrapings, biopsies, blood tests and microscopic examination of the bacteria to determine the underlying cause. He may also culture the bacteria to determine the best antibiotic for treatment.
Treatment
-
Your veterinarian will prescribe a long-term course of antibiotics and possibly topical medications as well. It is important to maintain a course of antibiotics for at least 21 to 30 days to ensure complete recovery.
Follow-up
-
A medicated shampoo containing benzoyl peroxide or chlorhexadine can be used to enhance recovery and to reduce recurrence. Since there is a chance of the bacteria reaching the bloodstream, it is important to follow the treatment plan and to ensure that the treatment is successful.
