Hi Jo D-
The RC S/O diet should only be prescribed for struvite crystals. It helps acidify his urine which helps dissolve the crystals. If he has calcium oxalate crystals, he would need a diet that makes the urine more alkaline to help stop the formation of anymore. My understanding is that they cannot be dissolved, but may be able to flushed out with a lot of moisture added to the diet.

You have your hands full. Good luck!

Edit: I’m sorry, I think I may be incorrect about the RC s/o. It actually may be for both struvite and oxalate crystals. I’ts the Hill’s c/d that acidifies the urine. I think the s/o neutralizes the ph levels and salt is added to promote thirst encouraging the dog to drink more and flush the crystals out. Either way, it is best to add as much moisture to your dog’s diet to rid of either type of crystal.
