First, let me say that I’m not a vet. But, I would suggest a visit to your vet to determine the type of crystals and to see if there is an infection present. There are different types of crystals and treatments vary. Struvite crystals seem to form if there is an infection, but Oxalate crystals are a different matter. There are also other types. One thing is certain, though, and that a dog that is prone to uti’s or crytals needs lots of moisture in the diet. Moisture is actually good in any animal’s diet, imho. If I were you, after speaking to my vet, I would check into 4-5 star, high quality foods. Whether you feed all canned, regular raw or freeze dried raw that’s been rehydrated, or kibble topped with wet food of sime kind (either of the above mentioned or wholesome people food) moisture is necessary to help flush out the kidneys. If you feed only kibble, then I would still add water or no-sodium/low-sodium broth to it. There are also supplements that might help with urinary issues like cranberry, vit. C, omega 3’s etc. Again, I would ask your vet for recommendations. There are also regular posters here that have had dogs with kidney issues from birth that may post with some great suggestions. Good luck to you and I hope this helps!
