There is currently no supplement available that will prevent Cystine bladder stones unfortunately. Our only options here are a prescription diet available through your veterinarian. The diet ensures that the ph of the urine is optimal for crystals not to grow and also that the pet drinks more water and helps dilute the urine. Supplements would not be strong enough to make those kinds of changes; therefore we have to approach crystal management from a diet change perspective only. I hope that you are able to manage Roy's crystal issue well going forward. Best of luck and take care. : )

    No, it is best to just do the strict urinary prescription diet. The key to not making stones is keeping the pH of the urine at a constant. The food is designed to do that. Do not give any other foods, treats or supplements as they will change the pH. All this being said, some dogs are just prone to making stones and even if you keep him on the strict diet there is no guarantee that he will not continue to make stones. Hope this clarifies. Great question!
