option to consider in many cases of canine sporadic cystitis. Palliative treatment with non-steroidal anti- in ammatory drugs (NSAIDS) can be initiated, where no contraindications are present.
Choice of antibiotic treatment should ideally be based on susceptibility data. This is however rarely rapidly available, and initiation of empiric treatment of non- recurrent cases is justi ed if signi cant bacteriuria is found on in-house QBC. Amoxicillin and potentiated sulfonamides (TMS) are both accumulating in high concentrations in urine and are therefore generally
good  rst line agents towards the most common uro- pathogens. Resistance-rates do however vary across Europe (6), and (when available) local/regional guidelines should be consulted to guide empiric choice of antibiotic class.
There is very sparse evidence with regard to optimal duration of treatment in companion animal UTI including canine sporadic cystitis (7). Recent randomized controlled studies suggest that short term (3 days) treatment of TMS (8) and high dose enro oxacin (9) is non-inferior to long term (7-14 days) treatment with beta- lactams in treating canine sporadic cystitis. Short term treatment with amoxicillin has not been investigated in dogs, but in people a 3-5 days course of pivmecillinam
is considered adequate (10). The bene ts of short
term treatment include not only reduced antimicrobial resistance selection pressure, but also reduced adverse effects, increased compliance and reduced costs.
Monitoring of bacteriuria during or after completion of therapy is not advised unless clinical signs persist or recur.
