The daily nutritional requirements of calcium for an adult dog is listed as 119 mg/ kg of body weight. For an 11 lb dog, that would calculate to approx 595 mg of calcium total, but nutrition can be much more complicated than this suggests as levels of some nutrients can affect absorption of other nutrients. The ratio of calcium to phosphorous is just as important as the the calcium level alone.
If you are going to feed a homemade diet, I would strongly encourage you to consult a veterinary nutritionist so you make sure you are meeting all your dog's nutritional needs while keeping everything in balance. Here are a website that lists the board-certified veterinary nutritionists:
and here are two websites where veterinary nutritionists can help you formulate homemade diets specific to your pets needs via online consultation. There are charges for these services.

Calcium phosphate crystals are pretty uncommon. Calcium phosphate crystals are most often associated with an increased calcium levels in the blood stream, so that is something that should be checked if that has not already been done.
If there are stones (not just crystals) present within the urinary tract, they will need to be removed surgically as there are not any diets that will dissolve these.
If the homemade diet that this dog has been on was not formulated by a nutritionist, there is probably a good chance that the diet may be a contributing factor here and getting him on a more balanced diet could help prevent additional crystals from forming in the future. Also, it would be a good idea to try to keep your dog's urine as dilute as possible as that makes it harder for crystals to form.
Let me know if you have additional questions.
