I think that there is not any connection between the changes you mantioned and the contact with the skunk. Your dog is suffering from deep pyoderma,primary bacterial, or secondary bacterial infection on some primary agent. First perform bacterial cuture and antibiogram sensitivity test for treatment of the infection. Examine the skin for parasites, especially Demodicosis. Do fungal culture if previous tests are negative. Other that it should examined are the anal sacs.
Treatment: -Treat your god aproximately 6-8 weeks, or at least 2 weeks beyond the complete clinical remision of the infection with the systemic antibiotic selection based on the results of a bacterial culture and sensitivity tests. -Consult your vet for performing topical terapy. -Deep pyoderma is rarely a primary desease process and is related to some other underlying problem. NOTE this to your vet and treat the underlying problem after you cure the secondary bacterial infection.
