Plain-English summary
A study looked at 151 unmedicated dogs with ear infections (otitis externa) to identify the types of bacteria causing the problem and how resistant they were to common antibiotics. The most common bacteria found were Staphylococcus pseudintermedius and Staphylococcus aureus, with many showing resistance to multiple antibiotics. Amoxicillin combined with clavulanic acid and oxacillin were the most effective treatments. This suggests that if your dog has an ear infection, a vet may need to perform tests to determine the right antibiotic to use for treatment.

Abstract
The diversity of species of the genus Staphylococcus sp. and the antimicrobial resistance of isolates from 151 unmedicated dogs of both sexes with a clinical diagnosis of otitis were recorded. Ninety-one isolates of Staphylococcus spp. were identified by biochemical reactions and tested for susceptibility to 15 antimicrobials. Coagulase-positive species were most common; S. pseudintermedius (38.4%), S. schleiferi schleiferi (15.4%), S. aureus (14.3%), S. epidermidis (11%), S. simulans (11%), S. schleiferi coagulans (8.8%) and S. saprophyticus (1.1%). All the isolates showed resistance to at least one drug and 89% were multiresistant. Amoxicillin combined with clavulanic acid and oxacillin were the most effective, while resistance was widely observed for neomycin and erythromycin. The results highlight the recognition and the potential need for bacterial culture with species identification and antimicrobial susceptibility tests for appropriate antimicrobial therapy.
