I am not crazy about the prescription diets either. According to this study in 2002 the hills diet is not even recommended by the The American Journal of Veterinary Research yet the vets are still recommending it. It sounds like you need a diet that is a low-purine diet not low calcium. The foods that are the lowest in purine are all full of calcium. There is a list so you can choose a food that has the right ingredients to give your dog the best chance to recover.
according to the list you might choose venison and sweet potato or rice as a low purine food.

In the past, diets restricted in both protein and phosphorus were thought to reduce the risk of calcium oxalate formation. Studies found, however, that dietary phosphorus restriction increased calcium absorption and the risk of calcium oxalate formation, while higher levels of dietary protein reduced the risk of urolithiasis. Current recommendations for dogs prone to forming CaOx stones say that diets should not be restricted in protein, calcium, or phosphorus.
In February 2002, The American Journal of Veterinary Research published a study conducted at the University of Minnesota College of Veterinary Medicine’s Minnesota Urolith Center that compared dietary factors in canned food with the formation of calcium oxalate uroliths in dogs, with surprising results. Canned diets with the highest amount of carbohydrate were associated with an increased risk of CaOx urolith formation. Contrary to commonly accepted beliefs, the study concluded that “canned diets formulated to contain high amounts of protein, fat, calcium, phosphorus, magnesium, sodium, potassium, chloride, and moisture and a low amount of carbohydrate may minimize the risk of CaOx urolith formation in dogs.”
In contrast, both Hill’s Canine u/d and Royal Canin Urinary SO, often prescribed for dogs prone to forming CaOx stones, are extremely low in protein, and restrict calcium, phosphorus, magnesium, and potassium (Royal Canin is less restrictive than u/d).
