Plain-English summary
A group of dogs with urinary tract infections (UTIs) had urine samples tested for staphylococci bacteria, which can cause these infections. Out of 348 dogs, 70 samples grew staphylococci, with the most common type being Staphylococcus pseudintermedius. Alarmingly, all of the bacteria were resistant to at least one antibiotic, and over three-quarters were resistant to multiple drugs. This highlights the growing problem of antibiotic resistance in bacteria causing UTIs in dogs, which may complicate treatment options.

Abstract
This study determined the diversity of species and antimicrobial resistance of staphylococci isolated from dogs with a presumptive diagnosis of urinary tract infection (UTI). Urine samples from 348 dogs with clinical signs of UTI, according to clinical examination and urinalysis, were processed for isolation of Staphylococcus. Colonies in pure culture were identified by biochemical reactions and tested for susceptibility to 15 antimicrobials. Seventy isolates of staphylococci were obtained (20.1%). Staphylococcus pseudintermedius was the most frequent species (32.8%), followed by S. epidermidis (18.6%), S. simulans (15.7%), S. schleiferi schleiferi (11.4%), S. aureus (11.4%), S. schleiferi coagulans (7.2%) and S. saprophyticus (2.9%). All the isolates were resistant to at least 1 drug and 77.1% were multiresistant. The study reports the alarming antimicrobial resistance of members of the Staphylococcus genus isolated from canine UTI and highlights the importance of coagulase-negative staphylococci in its etiology.
