I think listening to a veterinarian that has examined and diagnosed your dog and knows the dog’s history would be wise. Bladder stones often have a genetic component.
Your dog has a serious condition that requires the expertise of a veterinary professional.
Prescription dog foods are specially formulated as part of the treatment for specific medical conditions. It’s not just about the ingredients, it’s about trying to prevent your dog from having continued problems.
Also, you may want to discuss with your veterinarian, about the possibility of medications that might help. I’m not talking about food supplements/scams.
