Re: How long does it take for antibiotics to take effect?
Unfortunately, if you take her to the vet after having been giving her Clavamox, any UA or urinary culture that your vet may run may not identify any bacteria because of the Clavamox. That does not, however, necessarily mean that there is no infection present ... or that there is. I don't think the tests will be able to produce reliable results either way because of the Clavamox already in her system. You should ask your vet about that before having her tested for UTI.
If, however, your vet wants to test her for urinary crystals or for bladder or kidney stones, those shouldn't be affected by the Clavamox at all.
