If your dog eats home-cooked food, a daily dog multivitamin (also called a balancer or premix) is what stops them from quietly developing nutrient deficiencies. In Australia, the safe approach is one designed for AAFCO complete-and-balanced standards. Here's how to pick one — and what to watch for.
I'm Teddy. My human cooks for me every Sunday. For about three months, she didn't add a multivitamin to my food. I ate well, looked well, no obvious problems. Then she ran my recipes through a nutrient profiler.
I was getting roughly 38% of my daily calcium. About half the iodine. Around 70% of the zinc. Vitamin E was at 22% of where it needed to be. The food looked complete — meat, vegetables, rice, the lot. It wasn't.
This is normal. Almost every home-cooked dog diet in Australia, without a dog multivitamin or premix added, falls short on the same handful of nutrients. The food tastes fine, the dog looks fine, the problem hides for years and then shows up as something else — dental disease, slow recovery from a small injury, soft stools that nobody can explain.
What a dog multivitamin actually does
The term "dog multivitamin" gets used loosely. In Australia you'll see three different things sold under that name:
- Treat-style chewable vitamins. These are flavoured chews with small amounts of common vitamins. They're top-ups, not balancers. Useful if your dog eats complete kibble and you want extra joint support — useless if your dog eats home-cooked food.
- Specific-nutrient supplements. A calcium powder, a fish oil capsule, a vitamin E drop. Each one fixes one deficiency. To balance a home-cooked diet this way you'd need 8 to 12 separate products, all dosed correctly, every meal.
- Complete-diet balancer powders, also called premixes. One scoop, designed to fill every gap in a meal of meat + vegetable + carb. This is what AAFCO-aligned dog food premixes are.
If you're cooking for your dog, the third option is the only one that actually does the job. My human's Premix is in this category.
What "complete and balanced" means
The phrase "complete and balanced" is a regulatory standard set by AAFCO — the Association of American Feed Control Officials. Their nutrient profile lists every essential nutrient a dog needs per 1,000 calories of food, broken into adult maintenance, puppy, and senior life stages. In Australia, AAFCO is the gold standard most veterinary nutritionists reference. Commercial dog food sold here usually claims AAFCO compliance even though the standard is American.
For home-cooked food, "complete and balanced" means the meal — protein + veg + carb + multivitamin — collectively hits every minimum in that AAFCO profile, and stays under every maximum. There are 36 essential nutrients. Most home-cooked diets miss 6 to 10 of them.
What's typically missing from home-cooked dog food
If you cook for your dog without a multivitamin, the deficiencies are predictable. My more detailed guide on this breaks down the exact gaps, but as a summary:
- Calcium — meat is very low in calcium and very high in phosphorus. Without a balancer, the Ca:P ratio is upside down, which over years degrades bone density.
- Iodine — Australian soils are iodine-deficient, our meat reflects that, and home-cooked diets typically deliver about 50% of what a dog needs.
- Zinc — borderline-low in most home-cooked diets. Long-term zinc deficiency shows as dull coat, slow wound healing, recurrent skin infections.
- Vitamin D — dogs don't synthesise vitamin D from sunlight the way humans do. Their diet has to provide it.
- Vitamin E — particularly low when the protein source is lean (chicken breast, kangaroo, turkey).
- Manganese, selenium, copper — trace minerals that are hard to hit from food alone.
- Choline — often missed entirely in home-cooked diets.
The Australian context
Most multivitamin and premix products on the Australian market are American or European formulas, repackaged for AU. That's mostly fine — dogs are dogs — but two nutrients matter more for Australian dogs specifically:
Iodine. Australian soil has unusually low iodine across the eastern states. Our meat, eggs, and vegetables reflect that. American premixes assume American soil iodine levels, which can leave Australian dogs short. Look for a product that dose iodine for the local context, or accept you may need a separate iodine source.
Vitamin D. Australian fortified dairy and grain products have lower vitamin D supplementation than American ones. If your dog's diet is mostly lean meat (which is naturally low in vitamin D), the local context makes a difference.
How to evaluate a dog multivitamin
Five questions to ask before you buy:
- Does it claim AAFCO complete-and-balanced status, and for which life stage? Adult maintenance is different from puppy growth. Make sure it matches your dog.
- Does it tell you the dose per kg of finished food, or per kg of dog? Per kg of finished food is the safer measurement — it scales properly whether your dog eats 200g or 800g a day.
- What's the source of calcium? Calcium carbonate is cheap and fine. Bone meal is fine. Eggshell powder is also fine. If a product hides its calcium source, ask.
- Where is it manufactured? Australian-made products go through Australian regulatory pathways (APVMA for therapeutic claims, FSANZ for general food). Imported products vary.
- Does the brand publish a full nutrient analysis? If they don't show you the numbers, they don't want you to check them.
Our approach
My human built The Premix because she got tired of doing the maths every Sunday. One scoop per 200g of cooked food. Designed for AAFCO adult maintenance. The Australian iodine context is baked in. The full nutrient panel is published — every ingredient and what it does is listed.
That's it. You bring the protein, vegetables, and carb. We bring the balancing minerals and vitamins. The whole diet ends up complete, balanced, and roughly a quarter of the cost of fresh-delivery dog food.
Common questions
How is a dog multivitamin different from a premix?
The words get used interchangeably. Technically a "multivitamin" suggests a top-up product, a "premix" suggests a complete balancer. Functionally, for home-cooked diets, you want the complete balancer regardless of what the label says.
Can I just use a human multivitamin?
No, and this matters. Human multivitamins contain ingredients that are toxic to dogs (xylitol, sometimes iron at toxic doses). They also miss things dogs need (taurine, certain amino acid ratios). Always use a dog-specific product.
Do I need a multivitamin if I feed kibble?
No. Commercial complete-and-balanced kibble is already AAFCO-compliant. Adding more vitamins on top can push some nutrients into excess. Multivitamins are for home-cooked or raw diets.
How quickly will I see a difference?
Mostly you won't. The point of a balanced diet isn't a visible change — it's the absence of slow, invisible damage from deficiency. The biggest "result" of adding a complete dog multivitamin to a home-cooked diet is that 10 years from now your dog's joints, bones, coat, and dental health hold up the way they should.
