Myths about Supplements to your dogs food, including Calcium. Good info:
1. “A multivitamin added to the food will cover any gaps.”
The question here is this: Which multi, and with which diet? Any unsupplemented home-prepared diet will be low in some nutrients and adequate or high in others. But because there is no standard formulation for human multivitamins and they can vary greatly in what they include, just tossing one in the dish is not the answer.
Choosing an all-purpose multi made specifically for dogs doesn’t necessarily solve the problem either. These usually contain very low levels of nutrients because it’s assumed they will be added to commercial food, and so are unlikely to provide enough supplementation to round out a homemade diet. This is why “balanced” is not just a buzzword; it’s a valid and essential aspect of proper nutrition. Once you understand your dog’s nutritional needs, work out what her diet actually contains and then add what’s missing.
2. “I’m adding yogurt to my dog’s food daily so she’s getting enough calcium.”
Dogs require fairly high levels of calcium, and yogurt absolutely won’t cut it. Here’s a quick example: My own 75-pound dog has a daily requirement of 1,840 mgs of calcium, and since I use quite a bit of fiber in his diet in the form of brown rice, I want to offset any absorption issues and ensure that he gets about 2,000 mgs per day, or 14,000 mgs per week. His weekly diet alone—turkey, liver, sardines, brown rice, ground lamb and acorn squash—only provides 1,750 mgs. That means I need to add over 12,000 mgs of calcium; in other words, more than 40 cups of plain yogurt.
Calcium supplementation is always necessary unless you are feeding raw bones. I recommend using a commercial carbonate or citrate form of calcium, or an eggshell crushed into a fine powder—one teaspoon of this powder (about 5.5 grams) equals roughly 2,200 mgs of calcium carbonate. To use eggshells, rinse them well and then bake for about 10 minutes at 300 degrees; use a small grinder to make the powder. Bone meal can be used if there is also a need to add phosphorus, but many homemade diets supply plenty of this mineral.
