Hi Graciela-
Sorry to hear about your pup! You could try http://www.balanceit.com to formulate a recipe for your dog. However, if your dog has a health condition, they need to work with your vet a bit to ensure it fits your dog’s needs.
I have a cat who produces struvite crystals and ended up with a life threatening blockage about 3 or 4 years ago. Since then, I have been feeding him Royal Canin kibble with an s/o index. They actually have five or six formulas with the s/o index for cats. I feed him the one called “Calm”. I think they have it for dogs too.
He hasn’t had another issue. I also feed him canned and have a water fountain to ensure that he gets plenty of moisture in his diet.
I believe the s/o index helps prevent further stones. I just don’t look at the ingredients. Just the results!!
Good luck!
