Does Your Dog’s Diet Have Hidden Nutritional Gaps?
By Jolandie Koen — Certified Pet Nutritionist & Animal Naturopathy Practitioner
I want to ask you something honest.
When last did you actually know — not guess, not hope — but truly know what nutrients your dog is getting from their daily food?
I ask because I’ve been doing pet nutrition consultations for years, and one of the most common things I see is this: a dog owner who is genuinely doing everything right. They’re feeding raw, they’re rotating proteins, they’re adding supplements. They love their dog deeply and they’re trying hard.
And yet, when we actually sit down and analyse the diet properly, there are gaps. Quiet ones. The kind that don’t show up immediately — they accumulate slowly and reveal themselves months or years later as a dull coat, low energy, recurring skin issues, or more serious health conditions.
This isn’t about doing something wrong. It’s about the fact that without actually measuring, we’re always guessing.
The Most Common Nutritional Gaps I See in Dogs
After years of working with dogs on raw, homemade, and mixed diets, these are the deficiencies I come across most often:
Omega-3 (EPA + DHA) This is by far the most common gap I see. Most dogs get plenty of omega-6 from meat, but unless oily fish or a quality fish oil is included regularly, omega-3 is almost always deficient. Omega-3 supports joint health, brain function, skin and coat condition, and reduces chronic inflammation.
Vitamin D Dogs cannot synthesise Vitamin D through sun exposure the way humans can — they rely almost entirely on dietary sources. Unless oily fish (sardines, salmon, mackerel) or egg yolk features regularly in the diet, Vitamin D is often low. It plays a critical role in calcium absorption, immune function and bone health.
Zinc Zinc deficiency is more common than most people realise, particularly in dogs fed predominantly chicken. Red meats like beef, lamb and venison are significantly higher in zinc. Deficiency shows up as poor coat condition, slow wound healing and a weakened immune system.
Calcium-to-Phosphorus Ratio This one is especially important in raw-fed dogs. If raw meaty bones aren’t included — or aren’t included in the right proportion — the calcium-to-phosphorus ratio can become skewed, which over time affects bone density, muscle function and organ health.
Vitamin B12 B12 is found almost exclusively in animal foods, so dogs on a whole-food diet generally do better than those on plant-heavy diets — but if organ meats are limited or absent, B12 can still be low. It’s essential for nerve function, red blood cell production and energy metabolism.
Why Guessing Isn’t Good Enough
Here’s the honest truth: even the most experienced raw feeders can miss things. Not because they aren’t knowledgeable, but because nutrition is genuinely complex. Every dog has different needs based on their age, size, activity level and health status. A puppy needs almost double the calcium of an adult dog. A senior dog needs more omega-3 for joint support. A dog with kidney disease needs phosphorus restricted significantly.
Without actually running the numbers against a recognised standard — like the NRC (National Research Council) canine nutritional guidelines — we’re working with educated guesses. And for the dogs we love, I think we can do better than that.
What the Canine Nutritional Gap Analyser Does
This is exactly why I built the Canine Nutritional Gap Analyser.
You enter your dog’s details — their name, weight, life stage, breed size, activity level and health condition — and then you log exactly what they eat in a typical day from a database of 80+ whole foods. Everything from muscle meat, fish, organ meat and raw bones, to eggs, vegetables, fruits, oils, seeds and supplements.
The analyser then calculates your dog’s daily nutritional intake against NRC canine standards — adjusted specifically for your dog’s profile — and gives you an instant, colour-coded report across 13 essential nutrients:
- Protein
- Fat
- Calcium
- Phosphorus
- Zinc
- Iron
- Vitamin A, D and E
- Vitamin B12
- Omega-3 (EPA + DHA)
- Copper
- Manganese
Each nutrient is scored as Deficient, Low, Adequate, High or Excessive — and you receive targeted whole-food recommendations to close every gap identified.
What I’m especially proud of is the health condition protocols built into the tool. If your dog has kidney disease, the analyser automatically restricts phosphorus and adjusts protein recommendations. If they have pancreatitis, fat is kept very low. If they’re diabetic, the focus shifts to low-glycaemic, high-fibre feeding. These aren’t generic suggestions — they’re condition-specific dietary protocols built in to every analysis.
Whole Foods That Close the Most Common Gaps
If you’re reading this and already suspecting your dog might be missing something, here are a few simple additions that make a big difference:
🐟 Sardines or salmon — add 2–3 times per week for omega-3 and Vitamin D 🫀 Beef or chicken liver — even 30g twice a week dramatically boosts Vitamin A, B12 and iron 🦴 Raw meaty bones — the best natural source of calcium in the right ratio 🥚 Whole eggs — add 3–4 times per week for B12, Vitamin D, healthy fat and protein 🌿 Kelp — a small daily pinch provides iodine and trace minerals most dogs never get 🐟 Salmon or fish oil — a daily addition for dogs who don’t eat fresh fish regularly
These aren’t expensive or complicated additions. They’re whole foods your dog’s body was designed to thrive on.
