This case aimed to evaluate the role of Enterobacter cloacae (E. cloacae), a rare gram-negative bacterium, in the etiology of pyoderma and generalized demodicosis in a 7-month-old Pug. Demodex canis (D. canis) and E. cloacae were isolated from deep skin scraping and biopsy samples. Miticidal treatment included afoxolaner and milbemycin oxime (2.5–5 mg/kg and 0.5– 1 mg/kg, respectively). Antibacterial therapy consisted of cefazolin (20 mg/kg, IV, BID) and benzylpenicillin + dihydrostreptomycin (0.5 mL/5 kg, IM, SID) until culture and sensitivity results were obtained. The dog was returned to its shelter, where treatment was continued by the veterinarian and owner. Unfortunately, it died on the third day post-treatment. This case highlights that rare pathogens such as E. cloacae can contribute to severe, refractory demodicosis with secondary pyoderma. Pending antibiogram results, using less commonly employed antibiotics may help address resistance. Regular bacterial cultures and antibiograms are essential for identifying both common and rare pathogens and monitoring their resistance profiles, thus improving treatment success in complex dermatological cases.
