This is the single most powerful skill we can teach you. Once you can read a pet food label honestly, you'll never be misled by marketing again — for the rest of your dog's or cat's life.
Every bag of pet food in Canada is required to display a "Guaranteed Analysis" panel. It looks something like this:
Crude Protein (min) — 26%
Crude Fat (min) — 14%
Crude Fibre (max) — 5%
Moisture (max) — 10%
This panel is the most-cited and most-misunderstood part of any pet food bag. Here's what they're hiding from you.
"My ACANA has 35% protein! That's WAY more than your raw food at 12%!"
This is the most common mistake pet parents make. The numbers are not directly comparable until you convert both to a "dry matter basis."
The Math:
Dry Matter % = Nutrient % ÷ (100% − Moisture %) × 100
Example 1 — Premium Kibble:
26% protein at 10% moisture
= 26 ÷ (100−10) × 100
= 26 ÷ 90 × 100
= 28.9% protein on a dry matter basis
Example 2 — Fresh Raw:
12% protein at 70% moisture
= 12 ÷ (100−70) × 100
= 12 ÷ 30 × 100
= 40% protein on a dry matter basis
Once you do the math correctly, the raw food has far more protein per gram of actual food than the kibble — even though the bag number looked smaller. The kibble was just inflated by being dehydrated.
Always do this calculation when someone tries to sell you on protein percentages. The bag number alone tells you nothing.
Here's the second trick: the Guaranteed Analysis says "Crude Protein" — but it does not distinguish between protein from chicken and protein from peas. To a chemistry test, they look the same. To your dog's digestive system, they're very different.
Plant proteins (peas, lentils, chickpeas, potato protein, pea protein concentrate) are:
• Significantly less bioavailable than animal protein
• Missing or low in critical amino acids like taurine and methionine
• Linked to dilated cardiomyopathy (DCM) in dogs when used as primary protein source — FDA investigation ongoing since 2018
• Cheap to source, which is why manufacturers use them
A bag claiming "32% protein" with peas, pea protein, lentils, and chickpeas in the top ingredients may have only 18-20% actually-usable animal protein. The rest is plant protein artificially inflating the number.
How to spot this: If you see legumes (peas, lentils, chickpeas, beans) in the top 5 ingredients of any pet food, the protein percentage on the label is partly plant-based. Adjust your expectation downward.
Notice what is NOT on the Guaranteed Analysis: carbohydrates. AAFCO does not require carb disclosure. Why? Because if dog and cat parents could see it, they'd be horrified.
How to estimate carbs in any kibble:
Carbs % ≈ 100 − Protein − Fat − Moisture − Fibre − Ash
Most kibble bags don't list ash, but it's typically 6-8%. Use 7% as a working estimate.
Example calculation on a "premium grain-free" kibble:
Protein 32% + Fat 16% + Moisture 10% + Fibre 5% + Ash 7% = 70%
Remaining = 30% carbohydrates
For context: dogs and cats have minimal evolutionary need for carbohydrates. Wild canid stomach analysis shows ~5% plant matter. Cats are obligate carnivores with essentially zero carb requirement. Yet most kibble — even "grain-free" premium kibble — runs 30-50% carbs by necessity, because you cannot extrude a kibble pellet without starch as binding material.
Pet food ingredients are listed in descending order by weight before processing. The pet food industry has perfected the art of manipulating how this reads.
Most of what you need to know about a pet food is in its first 5 ingredients. Read them carefully. Here's what to look for:
✅ GOOD signs in the first 5:
• A single, named whole meat as ingredient #1 ("Chicken," "Beef," "Lamb," "Salmon")
• Named meat MEAL as #2 if there's extra protein boost (e.g. "Chicken Meal" — concentrated protein)
• Whole vegetables in their natural form ("Sweet Potato," "Carrots," "Pumpkin")
• Identifiable, simple, real food words
❌ RED FLAGS in the first 5:
• "Chicken By-Product Meal" as #1 — rendered necks, feet, intestines and undeveloped eggs (by AAFCO definition it excludes feathers). Not dangerous, but it tells you the named meat is not the main ingredient
• Corn, corn meal, corn gluten meal, or wheat as primary ingredients — cheap fillers
• "Meat And Bone Meal" — unspecified species, lowest-grade rendered product
• "Animal Fat" without species specified — usually rendered restaurant grease
• Multiple legumes (peas + lentils + chickpeas + pea protein) — plant protein inflation
• "Animal Digest" — chemically hydrolyzed slurry of unspecified parts
A bag lists: "Chicken, Corn Meal, Corn Flour, Corn Gluten Meal, Wheat, Wheat Bran..."
Chicken is first — so it must be the primary ingredient, right? Wrong.
Corn appears three times in different forms. If you mathematically combine Corn Meal + Corn Flour + Corn Gluten Meal, the total corn content far exceeds the chicken. The manufacturer split corn into three separate ingredient names so each one individually weighs less than chicken — making chicken appear first.
This is called ingredient splitting, and it's legal. Watch for it especially with:
• Corn: corn, ground corn, corn meal, corn gluten meal, corn flour
• Peas: peas, pea protein, pea fibre, pea starch, pea flour
• Rice: rice, brewers rice, rice flour, rice bran, rice protein
• Potato: potato, potato starch, potato protein, potato flour
When you spot splitting: Mentally combine all forms of the same ingredient and re-rank the list. The "primary protein" claim usually evaporates.
"Fresh chicken" or "deboned chicken" sounds wonderful — and it weighs more than chicken meal because it's 70% water. But once that bag goes through extrusion (cooking at roughly 120–150°C under pressure, then drying), the water cooks off, and what remains is a small fraction of what was listed.
The reality: 100g of fresh deboned chicken becomes about 30g of cooked chicken in the final product. Meanwhile, 100g of "chicken meal" stays roughly 100g — because it's already been cooked down before being added.
This is why some honest manufacturers list "Chicken Meal" first instead of "Fresh Chicken" — they're showing you what actually ends up in the bag, not the pre-cooking weight that's designed to look impressive on the label.
Some of the most important information about your pet's food never appears on the bag at all.
Read any kibble label all the way down. You'll find a long list of vitamins and minerals at the end:
Vitamin E Supplement, Niacin Supplement, Vitamin A Supplement, D-Calcium Pantothenate, Riboflavin Supplement, Vitamin B12 Supplement, Pyridoxine Hydrochloride, Folic Acid, Vitamin D3 Supplement, Biotin, Menadione Sodium Bisulfate Complex...
These are synthetic vitamins added back into the food after processing destroyed the natural ones. Extrusion and drying degrade heat-sensitive vitamins (several B vitamins, vitamin E, some A and D), which is why every kibble adds a synthetic vitamin pack back after cooking. Manufacturers have to add synthetic versions back so the food meets AAFCO nutritional requirements.
A few problematic synthetic vitamins to watch for:
• Menadione Sodium Bisulfate Complex (Vitamin K3) — a synthetic form of vitamin K linked to liver toxicity in long-term studies. Banned for human use in many jurisdictions, still permitted in pet food.
• BHA / BHT / Ethoxyquin — synthetic preservatives. Ethoxyquin was originally a rubber stabilizer. Banned in human food, still permitted in pet food.
• Pyridoxine Hydrochloride (synthetic B6) — high levels can cause neuropathy.
Compare this to fresh raw food: vitamins are present in their natural, bioavailable forms because they were never destroyed in the first place. No synthetic supplementation needed.
Pet food manufacturers are not required to advertise their recall history. But it's public record. Before you buy a brand long-term, search:
"[Brand Name] pet food recall" + site:fda.gov
Many of the biggest "premium" brands have multiple Salmonella, mould, aflatoxin, and Vitamin D toxicity recalls in the past decade. A recall here or there happens to everyone — but a pattern of repeat recalls is a quality control red flag.
"Made in Canada" on the bag does not mean the ingredients came from Canada. A food can be assembled in Canada with proteins from China, vitamins from India, and fats from the United States. Most manufacturers will not disclose ingredient sourcing unless asked directly.
For sensitive pets, this matters. Knowing your kangaroo always comes from the same Australian region means consistent results when you find a protein that works.
Bring this checklist with you next time you're shopping anywhere. Use it on any bag of pet food in any store:
The 2-Minute Pet Food Audit:
Step 1 (15 seconds): Read the first 5 ingredients. Are they whole, named, identifiable foods? Or rendered meals, fillers, and split ingredients?
Step 2 (15 seconds): Check for ingredient splitting. Mentally combine all forms of the same ingredient (corn, peas, etc.). Does the protein still appear first?
Step 3 (30 seconds): Calculate carbs. 100 − Protein − Fat − Moisture − Fibre − 7% = carbs. Anything over 30% is high.
Step 4 (15 seconds): Convert protein to dry-matter basis if comparing across foods with different moisture levels. Use: Protein ÷ (100 − Moisture) × 100.
Step 5 (15 seconds): Scan for legumes in the top 5 (peas, lentils, chickpeas). If present, mentally subtract 10-15% from the listed protein number to estimate animal protein only.
Step 6 (15 seconds): Look for problem additives: by-product meal, BHA, BHT, ethoxyquin, menadione, artificial colors, "animal fat" without species.
Step 7 (15 seconds): Check the manufacturer. Who owns this brand? Search "[brand] parent company recall history."
Here's the most important point in this entire guide — and it's the one that almost nobody at chain pet stores will tell you:
No matter how good the ingredients are, the format itself sets a ceiling on what kibble can deliver.
Extrusion-cooked kibble — even premium kibble like ACANA, Orijen, or GO! — has structural limitations that cannot be overcome through ingredient quality alone:
• 10% moisture vs 70% in prey/raw — chronic dehydration regardless of ingredients
• Starch as a binder — kibble cannot hold its shape without it; absorbed nutrient values are lower
• Live enzymes destroyed at 200°C+ extrusion temperatures, regardless of source quality
• AGEs (Advanced Glycation End Products) created during high-heat cooking — pro-inflammatory compounds
• Synthetic vitamins required because natural ones don't survive processing
• 30-50% carbohydrates required as binding starch — cannot be reduced below this
Better ingredients in a kibble means a better kibble. But "better kibble" has a hard structural ceiling. Once the ingredients go through extrusion, the chemistry changes and many of the benefits the marketing promises are physically impossible to deliver.
This is why our recommendation hierarchy is structural, not brand-based:
Fresh Raw > Freeze-Dried Raw > Dehydrated Raw > Premium Kibble > Mass-Market Kibble
Format matters more than ingredients. The cleanest, most premium kibble in the world is still kibble.
