A review of the current concepts in canine urinary tract infections

Abstract
Traditionally, urinary tract infections (UTIs) have been categorised as either uncomplicated or complicated in veterinary medicine, with treatment differing for the two categories. In human medicine, there is an additional category: Asymptomatic bacteriuria, which is the presence of bacteriuria without symptoms of infection. Escherichia coli (E.coli) is the most common bacterial species involved in UTIs in dogs. Clinical signs can be absent in dogs with complicated UTIs, and this has been likened to asymptomatic bacteriuria (ASB) in people and has been termed subclinical bacteriuria (SBU) with the treatment recommendations for SBU in dogs have been adapted from human recommendations. There is a shift in the current treatment of UTIs to help minimise the development of antimicrobial resistance. Routine screening of dogs with conditions that may predispose them to UTIs has been discouraged as has the treatment of SBU. This has been due to the increase in antimicrobial resistance (AMR).
