Momo still has struvite crystals.

He's getting plenty of water & he's been on the canned Hill's C/D for over a month...vet thinks there could be an infection & prescribed clavamox. I asked her why she didn't do a culture & she said she didn't see any bacteria. Of course I forget to ask her to do a culture on the recheck.

I need to change vet hospitals, Momo has been going there since he was a puppy, but they seem so incompetent in this situation & I feel like I've wasted so much time & $...& my poor baby has an infection maybe (this isn't even verified but a guess or process of elimination!). To make matters worse, Princess also has struvite crystals (a lot of them) & the other vet in the same hospital didn't do a culture (again, I forgot to request it, but I called when I got home & the receptionist said he'll do the culture if he sees any bacteria). Is this the procedure? So I picked up antibiotics for both of them today.
Now after this round of antibiotics, should I do the recheck somewhere else? Please advise, I am so lost & having memory problems.
