Here's how to read pet food labels: start with the nutritional adequacy statement to see whether the food is complete and balanced for your pet's life stage, then check the guaranteed analysis, the ingredient list in order of weight, and the product name, whose wording tells you roughly how much of the named ingredient is inside. Words like premium or holistic on the front of the bag have no official definition, so they don't tell you much.
If you've ever stood in the pet food aisle comparing two bags that both say chicken in big letters, this is for you.
In Canada, labelling follows a Competition Bureau guide rather than a dedicated pet food law, and the World Small Animal Veterinary Association (WSAVA) has a practical checklist for owners. We've put the two together, panel by panel, so you can compare bags in the store and bring sharper questions to your vet.
Who sets the rules for pet food labels in Canada?
Less of the government than most owners expect. The Canadian Food Inspection Agency (CFIA) says the production and sale of pet food in Canada are currently not regulated by the Government of Canada, and that the CFIA doesn't regulate pet food labelling. It points to the Competition Bureau instead, which publishes a Guide for the Labelling and Advertising of Pet Foods.
That guide sets out what a label should carry and how names and claims should be worded. Packaging law adds the basics: a retail bag has to show a common name such as Dog Food or Cat Food in English and French, the net quantity in metric units, and the name and address of the dealer.
The most useful line on the bag is usually small and on the back: the nutritional adequacy statement.
Step 1: find the nutritional adequacy statement
This statement tells you whether the food is meant to be your pet's whole diet, and for which life stage. The Competition Bureau guide says a label should carry either a nutritional adequacy statement or the intended life stage, and it recognises four stages: all life stages, gestation and lactation, growth, and maintenance. The claim can rest on a feeding test or on a nutrient profile like the one from the Association of American Feed Control Officials (AAFCO).
In plain terms, complete and balanced for growth suits puppies and kittens, and maintenance means adult pets. All life stages means the food is formulated to meet the needs of growth too, which WSAVA notes can be more than an adult needs. And if you see for intermittent or supplemental feeding only, it isn't a complete diet; treats and toppers usually say this.
Speaking of treats, WSAVA suggests that treats and other foods that aren't complete make up no more than about 10 percent of your pet's daily calories.
Step 2: read the guaranteed analysis
The guaranteed analysis gives limits, not exact amounts. The Competition Bureau guide lists four items, shown on an as-fed basis:
| Line | What it means |
|---|---|
| Crude protein (minimum) | At least this much protein |
| Crude fat (minimum) | At least this much fat |
| Crude fibre (maximum) | No more than this much fibre |
| Moisture (maximum) | No more than this much water |
Canned food is mostly water, so its percentages look much lower than kibble's. That makes comparing wet with dry on these numbers alone misleading. If it matters for your pet, ask your vet how to compare them on a dry matter basis.
How to read pet food labels: the ingredient list
Ingredients are listed in descending order by weight, using common names rather than brand names, according to the Competition Bureau guide. That weight includes water. So a fresh meat listed first may end up weighing less, once the food is cooked and dried, than a dry ingredient further down.
The list tells you what's in the food, not how good the nutrition is. WSAVA's guidance puts more weight on who makes the food, whether they employ qualified nutritionists and how they test it than on any single ingredient.
What do dinner, with and flavour mean in a name?
They tell you how much of the named ingredient is in the bag, under percentage rules in the Competition Bureau guide. Two bags that both say beef on the front can hold very different amounts:
| Name on the bag | Share of the named ingredient |
|---|---|
| Beef Dog Food | 90 percent or more |
| Beef Dinner, Beef Formula | 25 percent to under 90 percent |
| Dog Food with Beef | 3 percent to under 25 percent |
| Beef Flavour Dog Food | Under 3 percent; the flavour source must be in the ingredient list |
With beef can mean as little as 3 percent beef. Beef flavour can mean less.
Which claims on the bag should you ignore?
Mostly the big words on the front. WSAVA notes that terms like holistic and premium have no regulated meaning, and the same goes for natural and human grade. The pictures of fresh vegetables are decoration, and a comparison with no stated basis (better than what?) isn't telling you anything.
The Competition Bureau guide does set some limits. Claims have to be accurate and not misleading, new or improved can only be used for one year of production, and words like cure, treat and prevent disease shouldn't appear on pet food at all, because those are drug claims.
Feeding directions are a starting point
Most complete foods carry feeding directions, and the guide says they're expected unless the product is for supplemental feeding or fed under veterinary direction. Use them as a starting point, then adjust with your vet based on your pet's body condition. A couch-loving cat in a one-bedroom apartment and a farm dog won't need the same scoop.
Note the food you choose, and any switch, in your pet's pet records so your vet can see the history. Pip, your pet's Wellness Buddy in the free PetGrid app, can tell you what an official guide says about feeding, but it isn't a vet. For other useful apps, see our best pet care apps in Canada.
Questions people ask
What is the most important part of a pet food label?
The nutritional adequacy statement. It tells you whether the food is complete and balanced, and for which life stage, such as growth or maintenance.
Is pet food regulated in Canada?
Not by a dedicated federal pet food law. The CFIA says production and sale of pet food in Canada are currently not regulated by the Government of Canada, and labelling follows a Competition Bureau guide plus packaging law.
What does an AAFCO statement mean on Canadian pet food?
It means the food was formulated to an AAFCO nutrient profile or passed an AAFCO feeding test for a stated life stage. The Competition Bureau guide recognises AAFCO as one basis for a nutritional adequacy claim.
What is the difference between chicken dinner and with chicken?
The amount of chicken. Under the Competition Bureau guide, dinner means 25 percent to under 90 percent of the named ingredient, while with means 3 percent to under 25 percent.
Does the first ingredient tell me the food is good?
Not on its own. Ingredients are ordered by weight including water, and WSAVA suggests judging a food more on the maker's expertise and testing than on the ingredient list.
The short version
Reading a pet food label well takes four checks: the nutritional adequacy statement, the guaranteed analysis, the ingredient list and the wording of the name. Ignore the marketing words, and if you're unsure, take the bag (or a photo of the label) to your vet.
It also helps to keep a note of what your pet eats alongside their health records, so any change can be traced later. The PetGrid app is free for pet owners.
