low sodium dog food

My dog has kidney and bladder stones.Her age prevents operation. he does not like me to be around
and leave the room whether to enter. Still Comes Around several times to get their pats and then out again. He refuses to eat the food from your vet wants to eat a diet cooking Ihave low sodium by increasing daily. Sometimes I like my cooking, but later in the day when you have nothing to do with it. Why not want me around? I know he loves me, but why do this? It also covers his head with a blanket, what about this? Anyone out there with recipes DOG?
When an animal is old and not very often to be quietly alone. His illness also may put off their food. This is much the same as when we feel bad and want some piece and quiet. Keep an eye on it. You'll know when to take back to the vet. For now just be nice to her and continue to give her a good home.
