Staphylococcus pseudintermedius is a common cause of skin and soft tissue infections in dogs but can also cause infections in cats and humans. The frequency of methicillin-resistant S. pseudintermedius (MRSP) strains is increasing worldwide. Here, we obtained 43 MRSP isolates from dogs (n = 41), one cat (n = 1) and the small animal clinic environment (n = 1) in Slovenia from the period 2008–2018, which underwent whole-genome sequencing (WGS) and antimicrobial susceptibility testing. Five sequence types (STs) were identified, with ST71 (32/43) and ST551 (8/43) being the predominant. In Slovenia, ST551 was first detected in 2016, whereas a decrease in the frequency of ST71 was observed after 2015. All isolates were multidrug-resistant and most antimicrobial-resistant phenotypes could be linked to acquisition of the corresponding resistance genes or gene mutations. Core-genome multilocus sequence typing (cgMLST) revealed several potential MRSP transmission routes: (i) between two veterinary clinics by a single MRSP-positive dog, (ii) between the environment of a veterinary clinic and a dog, and (iii) between a canine and a feline patient through the contaminated environment of a veterinary clinic. Of the six dogs that were additionally sampled from 14 days to five months after the initial sampling, each harbored the same MRSP strain, suggesting a limited within-host diversity of MRSP in symptomatic dogs. The present results highlight the importance of MRSP-positive dogs in the spread of veterinary care-associated MRSP infections and call for the implementation of strict control measures to reduce MRSP contamination in veterinary clinic environments originating from animal-contact surfaces.
