- Abstract Disc sensitivity tests were carried out on 2296 isolates of non‐pigmented, coagulase‐positive staphylococcal isolates from dogs in referral practice over the period 1980–96. Ninety‐eight isolates were from the ears, 1089 from other skin regions and 37 from mucosae. Resistance to penicillin increased from 69.0 to 89.3%. Oxytetracycline resistance remained at about 40%; resistance to erythromycin and lincomycin, and to co‐trimoxazole peaked at about 20 and 15%, respectively, in 1987–89 but has since fallen. Only a single isolate resistant to cephalexin was found between 1986 and 1996. No resistance to co‐amoxyclav, oxacillin, methicillin and enrofloxacin was demonstrated. Resistance of mucosal isolates was higher than those from skin. Multiple isolates from 90 dogs showed different resistance spectra in 56% of cases indicating that single swab samples are of limited value in determining optimal therapeutic antibiotics.
