Hi Hannah O-
I only have experience with struvite crystals. They can be dissolved, the oxalate ones cannot.
I feed my cat that has experienced a blockage an Royal Canin Rx Diet. It has an S/O index, which is supposed to help prevent both types of crystal/stones. I would imagine they would have a similar formula for dogs. Does your dog have a urinary tract infection? Often with dogs, they coincide with crystals.
Below is a link that may be helpful. I’m sure it is stressful. What is your vet recommending?
