My dog has crystals, but X-ray is clear. Still need prescription food?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Male | neutered | 8 years and 1 month old | 10 lbs

My pet did a urinalysis and crystallizations were noted. X-ray was done, and the crystals were NOT in his bladder. Blood test was normal. Should I still switch him over to the prescription kibble diet? I feel he does just fine with the raw diet. What should I do to remove the crystals? Should I just switch him over to the prescription diet?

Yes you should still switch him to the prescription diet, in an xray crystals cannot be seen unless they already formed a stone, so it does not mean that he doesn't have crystals in his bladder, it just means that the crystals have not formed bladder stones just yet. the prescription diet will prevent crystal formation as well as bladder stones.
