Okay.
I hope his appetite improves when his course of antibiotics are over. If he’s not getting at least adequate fluids let the vet know., maybe subq fluids would help?
My dog was on the Royal Canin S/O prescription for several months. I did have to add something to it so he would eat it though,
He had struvite and calcium oxalate. The struvite cleared up right away with treatment. Increased water and frequent bathroom breaks seem to help with all types of bladder stones.
I hope your dog feels better soon..
Peace
