My mixed breed, Lucy Mae, has a “mass” on her bladder. We don’t know yet if it’s malignant….didn’t want to do any biopsy yet (found it on an x-ray) because she’s acting great and kidney/bladder numbers seem okay for now. She’s also turning 12 years old and with her age, we’re in a wait and see mode. Anyway, she is eating Merrick grain free kibble topped with various canned food or freeze dried raw and water added. She is getting Standard Process Renal Support per my holistic vet. She also gets another urinary chew by Naturvet a couple times a week. So far, I have not reduced protein or anything like that and she’s doing fine. I know this may not be the same as your dog, but I still think a higher protein diet is best. Of course, I’m not a vet.
