What’s Really in the Bag?
Inside the Canadian Dog Food Industry · Article 01
A dog-food label tells you something. It doesn’t tell you everything. Here’s how to find the evidence that matters before deciding what to feed your dog.

The Short Version
A dog-food label is a starting point, not a verdict. In Canada, the main federal labelling law requires only a few basics on the bag: what the product is, how much is in it, and who it was made by or for. Most of the rest, including the nutrient numbers and the “complete and balanced” line, follows voluntary guidance, and no government agency approves the bag before it goes on the shelf. So read the label for what it can tell you: whether the food is a complete diet, which life stage it’s meant for, and how many calories it has. Then ask the company the questions the label can’t answer.
Five things worth knowing
The front of the bag is there to sell it. Photos, familiar ingredient names and words like “premium” or “holistic” tell you what the company wants you to notice. They’re of little practical use for judging nutrition (WSAVA, 2021). The useful information is usually in the small print on the back.
Find the line that says who the food is for. It should tell you whether the food is a complete diet and for which life stage. With a German Shepherd puppy, look for wording that says it includes “growth of large size dogs (70 lb. or more as an adult).” Bags sold in Canada don’t have to carry that wording, so if it isn’t there, ask the company and your vet.
The percentages on the bag need context. Protein and fat figures are minimums, not exact measurements, and water throws comparisons off. A canned food can look lower in protein than a kibble and turn out higher once the water is taken out of the calculation.
A company should be able to explain how it checks its food. Not publishing lab reports isn’t a warning sign on its own. But a manufacturer should be able to tell you who makes the food, how it’s tested and how problems are traced. If it can’t or won’t, be cautious (WSAVA, 2021).
You don’t need to switch foods to use any of this. If your dog is doing well on what you’re feeding, none of these questions is a reason to change. If there are digestive problems, weight changes or other health concerns, talk to your vet before you start swapping brands.

The deeper explanation
What Canadian law actually requires
Canada does regulate parts of pet-food labelling, but less of it than most people assume. Under the Consumer Packaging and Labelling Act, a prepackaged dog food has to show what the product is, in English and French, its net quantity in metric units, and the name and principal place of business of the dealer it was made by or for (Competition Bureau, 2001, s. 1.4; Consumer Packaging and Labelling Act). False or misleading representations are prohibited under that Act and the Competition Act (Competition Bureau, 2001).
That’s the legal minimum. The guaranteed analysis, the ingredient list and the nutritional adequacy statement come from the Competition Bureau’s 2001 Guide for the Labelling and Advertising of Pet Foods, which says plainly that it isn’t law. It’s a voluntary code of conduct and a benchmark the Bureau uses when it looks at possible misleading claims, even though it often says a label “must” carry things that aren’t legal requirements (Competition Bureau, 2001, Introduction). The guide also expects companies to keep the data behind their claims on file in case officials ask for it (Competition Bureau, 2001, s. 6.1). Nobody approves the bag before it goes on the shelf.
The Canadian Food Inspection Agency says pet food isn’t comprehensively regulated the way food for people or livestock feed is, and that its own oversight is limited to import and export requirements for animal products and by-products. Health Canada and Environment and Climate Change Canada can get involved when particular ingredients fall under their rules (CFIA, Regulatory oversight of pet food, treats and chews). So Canadian dog food isn’t unregulated, but a bag on the shelf hasn’t necessarily been tested by anyone in government for nutritional quality. Who regulates what, and where the gaps are, is the subject of a later article in this series.
Reading the numbers on the back
The guaranteed analysis usually lists minimum percentages for crude protein and crude fat and maximum percentages for crude fibre and moisture, stated “as fed,” meaning the food as it comes out of the bag (Competition Bureau, 2001, s. 2). Those numbers are limits, not measurements. A minimum crude protein of 26% means the company guarantees at least that much, not exactly that much. And “crude” is the right word. It’s a rough measure that tells you nothing about protein quality, the balance of amino acids, or how well your dog can digest and use it.
Water makes comparison harder again. Take two hypothetical foods. A canned food with 10% protein and 75% moisture is 25% dry matter, so its protein works out to 40% on a dry-matter basis. A kibble with 26% protein and 10% moisture is 90% dry matter, which puts its protein at about 28.9% (Merck Veterinary Manual). The can looked like the lower-protein food until the water came out.
That doesn’t make the can the better food. It means you can’t compare printed percentages until you account for moisture, and even then you’ve compared protein, not overall nutrition. The Competition Bureau’s guide asks the same of companies: comparisons should be dry against dry (Competition Bureau, 2001, s. 6.2). If you’re comparing foods with very different calorie densities, asking for values per 1,000 kilocalories gets around the moisture problem too (Merck Veterinary Manual).
The guaranteed analysis covers a handful of nutrients. The World Small Animal Veterinary Association (WSAVA) says companies should be able to provide a typical or average analysis for all essential nutrients, and should be reachable for questions about nutrients that aren’t on the label (WSAVA, Guidelines on Selecting Pet Foods, 2021). When you get one, ask where the figures came from. WSAVA distinguishes between values worked out from a nutrient database and values from chemical analysis of the finished food (WSAVA, 2021). The first is a calculation from the recipe. The second measured an actual sample. Both are useful, but neither proves every bag contains exactly those amounts.
What ‘complete and balanced’ means
The nutritional adequacy statement tells you whether the food is meant to be a complete diet, and for which life stage, or whether it’s only for intermittent or supplemental feeding (Competition Bureau, 2001, s. 5; WSAVA, 2021).
Most say the food is either formulated to meet a nutrient profile, often the Association of American Feed Control Officials (AAFCO) Dog Food Nutrient Profiles, or that animal feeding tests substantiate it (Competition Bureau, 2001, ss. 5.1–5.2). A formulation claim means the recipe was designed to provide specified nutrient levels. A feeding-test claim means dogs were actually fed the diet under a defined protocol. AAFCO’s model wording also allows a third version, saying a food is comparable to a product that went through feeding tests, which means the recipe that was tested and the one in your hand may not be the same (AAFCO model wording, as adopted in Kentucky regulation 12 KAR 3:039). None of these shows the food suits every dog for life, and none confirms that each batch made afterwards matches the one that was assessed. That comes down to manufacturing controls.
AAFCO is an American organization. Its name on a Canadian bag can look like a stamp of approval. It isn’t a Canadian government approval. It tells you which standard the company says it’s meeting (Competition Bureau, 2001, s. 5).
For a German Shepherd puppy, read the statement word for word. An adult-maintenance food isn’t meant for a growing puppy. Under AAFCO’s model wording, a food formulated for “growth” or “all life stages” has to say whether that includes or excludes “growth of large size dogs (70 lb. or more as an adult)” (12 KAR 3:039; AAFCO, 2023). Canada doesn’t require that wording, so a bag sold here may not carry it. If it doesn’t, ask the company, and involve your veterinarian. What makes a food nutritionally complete, and how those standards are set, gets its own article later in the series.
What happens after the recipe is designed
A recipe can look right on paper and still leave questions about what comes off the production line. WSAVA says manufacturers should have quality control covering ingredient validation, nutrient analysis of the finished diet, toxicology, bacteriology, and packaging and shelf-life checks before, during and after manufacturing (WSAVA, 2021).
Those checks answer different questions. Nutrient analysis shows whether a sample of finished food matches the food’s specifications. Chemical safety testing looks for specified contaminants, and a clean result for one substance says nothing about the ones nobody tested for. Microbiological testing, which looks for bacteria such as Salmonella or other signs of contamination, is harder than it sounds: US food-safety guidance points out that a sampling plan able to reliably detect low levels of a pathogen is seldom possible because of the number of samples it would take, and that lab methods have technical limits of their own (FDA/NACMCF, HACCP Principles & Application Guidelines). Batch coding and traceability let a company follow a problem back to particular production lots and recall them quickly (FDA/NACMCF, Appendix A). That matters, but it doesn’t make a batch safe.
You won’t find most of this on the package, and that alone isn’t a warning sign. The same guidance says an effective system controls hazards during production and needs relatively little end-product testing (FDA/NACMCF). A manufacturer can have solid controls without publishing a single lab report. It should still be able to explain them in terms you can follow, and there’s a difference between describing a system and showing you evidence that it works. “Rigorous quality standards” on a website is a description. How plants and contractors actually work gets its own article later in the series.
What a lab report can and can’t tell you
An independent lab report can be good evidence, especially when it identifies the product, the sample, the methods and the results. It’s also easy to read more into one than it holds. If a lab tests one sample of a recipe for calcium, that tells you about that sample, not every production batch, and it doesn’t show the food meets every nutritional requirement. A negative contamination result means the organism wasn’t detected in the portion tested, using that method, at that method’s detection limit. It isn’t a guarantee that every bag is free of it.
Before I’d treat a report as meaningful, I’d want to know which recipe and lot were sampled, who collected the sample and when, how it was handled, which methods the lab used, and whether the product tested is the one actually sold in Canada. Those are the same basic details food inspectors are expected to record when they take samples (CFIA, Sampling procedures).
Testing disclosure: Fluffy Shepherds hasn’t commissioned independent laboratory testing of any named dog food for this series. We won’t suggest otherwise, and we won’t rank foods on lab results we haven’t obtained and checked.
What I’d ask before choosing a food
Start with the package: the life stage, the adequacy statement, the feeding directions and the calories. Calorie information isn’t required on Canadian labels (WSAVA notes it’s only required in the US), so if it’s missing, ask (WSAVA, 2021).
Then ask the company for a typical nutrient analysis of the exact recipe, and whether those figures were calculated or measured. Ask what quality-control checks it runs and how it traces production batches. And ask who actually makes the food. The name on the bag belongs to the dealer the food was made by or for, which may not be the company running the plant (Consumer Packaging and Labelling Act; WSAVA, 2021). A clear answer doesn’t make a food right for your dog. But if all you get back is marketing language, you haven’t been given an answer.
If you’ve got a rescued Shepherd
With a rescue, you often start without the history. You may not know what the dog was eating before, whether its weight has been stable, or whether there’s a medical reason to choose a particular diet. So use the label for the basics: is this a complete food, and does it suit the dog’s age and size? Then watch how the dog actually does on it, and bring your vet in early if weight, condition or digestion seem off, rather than working your way through brands. If the dog’s doing well, leave the food alone. Feeding a rescued Shepherd, including transitions and health needs, gets fuller treatment in a later article in the series.
Fluffy Shepherds shares lived experience, observation and evidence-informed guidance. It does not diagnose behaviour or replace veterinary care. When health or safety is in question, involve the appropriate qualified professional.
