|I would do research before switching to raw food when a dog has struvite urolithiasis. There's a yahoo group called K9 kidney diet dedicated to nutrition and topics related to dogs with kidney and bladder problems, including recipes for home cooked foods. I am an advocate of raw diets, but the problem with them and dogs with bladder crystals is it's very tricky and may be worse if not correctly balanced. The thing with struvite urolithiasis is the pH in the bladder may be too high, so acidifying the urine with a cranberry powder may help by keeping the ph lower and also prevent bacteria from adhering to the walls of the bladder. But the struvite crystals come as a result of having too much phosphorus being filtered through the urine, without a binder, resulting in the formation of crystals. Phosphorus is found very heavily in animal meats, all of them have it, some more than others, but it's always high in animal protein. Raw diets being heavy in animal protein have even higher concentrations of this. I agree that vet specific diets are pretty crappy food, look at the ingredients, but the ones to prevent bladder stones do usually work because they have low animal protein content, which means low phosphorus, and are balanced with calcium, which will bind phosphorus in the urine to prevent formation of crystals. This is why soy is the primary protein source in those kinds of foods. Now the old school of thought is to limit animal protein, thereby limiting phosphorus. But now it's more of a balancing proportion thing using calcium carbonate to bind the phosphorus. Now you can still feed raw food diet, but I would get a recipe from a holistic vet to get the proportions of animal protein and calcium carbonate right. And you'd need to do urinalysis every month for at least six months to make sure you're balancing everything correctly. A lot of people have great success with raw diets, but I also know people with dogs with bladder stones that are fed only raw and keep developing the stones again. So I urge you do research struvite urolithiasis nutrition online, and join the K9 kidney diet group on groups.yahoo.com. Wealth of info there. Good luck!
