Prescription food/therapeutic diet.

Unless you can afford a veterinary nutritionist and have the time to cook and prepare meals for an hour or two a day.

Add water to all meals.

Honestly, I would go strictly by your veterinarian’s recommendations, I imagine the dog will need frequent lab work. Work closely with your vet.
Best of luck.
