Stand in any pet food aisle and the choices are dizzying: grain-free, ancestral, holistic, human-grade, with real chicken. The packaging is designed to appeal to you, not your dog. Behind it, a few details tell you far more than the pictures on the front.
1. Is it complete and balanced?
Look for a statement that the food is “complete and balanced” (in the US, according to AAFCO standards; in Europe, a “complete feed”) for your dog’s life stage — growth, adult maintenance or all life stages. If a food is labelled “complementary” or “for intermittent feeding”, it is a treat or topper, not a diet.
2. The words in the name matter
In the US, naming rules give you clues about how much of an ingredient is in the food:
- “Chicken dog food” — chicken is at least 95% of the product (excluding water).
- “Chicken dinner”, “platter” or “formula” — at least 25%.
- “With chicken” — as little as 3%.
- “Chicken flavour” — enough to detect the flavour; there may be very little chicken at all.
3. The ingredient list
Ingredients are listed by weight before cooking, so fresh meat, which is mostly water, can appear first even if dry ingredients provide more of the nutrition. Terms like “meat meal” are concentrated protein sources and are not necessarily lower quality. Ingredient lists are useful for spotting allergens, but they tell you little about overall quality.
4. Calories
Look for the energy content — kcal per kilogram or per cup. It varies hugely between foods, and it is what you need to work out how much to feed. Our food calculator turns it into a daily amount.
5. The questions labels don’t answer
The World Small Animal Veterinary Association suggests asking manufacturers a few questions — and choosing those that answer clearly:
- Do you employ a full-time, qualified veterinary nutritionist?
- Who formulates your diets, and what are their credentials?
- Are your diets tested with feeding trials, or formulated to meet standards on paper?
- What quality control do you use for ingredients and finished products?
Price and marketing terms are poor guides to quality. “Natural”, “holistic” and “human-grade” have little or no regulated meaning in many countries.
Changing food
Switch gradually over seven to ten days, mixing increasing amounts of the new food with the old, to avoid upset stomachs. If your dog is thriving — good energy, healthy weight, good stools, a shiny coat — the food you have is probably doing its job.
Questions owners ask
Is expensive dog food better?
Not necessarily. Price reflects ingredients, marketing and brand as much as nutrition. The manufacturer’s expertise and testing tell you more.
Wet or dry food?
Both can be complete and balanced. Wet food adds water and is often more palatable; dry food is cheaper and easier to measure. Many owners use a mix.
What does “by-products” mean?
By-products are parts of animals other than muscle meat, such as organs. Many are nutritious. The label word alone doesn’t mean poor quality.
