Dog food: how to choose the right diet without falling for marketing

Choosing dog food is not simply a matter of trusting the picture on the packet or the words ‘rich in meat’. Between dog kibble, wet food, grain-free recipes and formulas for sensitive pets, differences in ingredients, packaging and price can be significant.

To make the right choice, start with three checks: the complete food designation, whether it suits your dog’s profile and the product’s actual ingredients. Here are the criteria to review before filling your basket.

Common pitfalls when buying dog food

1. Confusing a highlighted ingredient with the overall composition

A packet may prominently feature chicken, lamb or duck without that protein accounting for all the animal-derived ingredients. To get a clear picture, check the detailed list: stated proportions, the presence of animal by-products, cereals, pulses, fats and nutritional additives.

The description ‘chicken dog food’ therefore does not necessarily mean ‘a single source of protein’. If this is important to you, look for a recipe explicitly described as a single source of animal protein, then check that the ingredients list confirms this claim.

2. Assuming ‘grain-free’ automatically suits every dog

Grain-free dog kibble generally replaces cereals with potatoes, peas, lentils or other sources of starch. This may suit a particular preference or need, but it is not enough to determine whether the food is balanced.

A complete dog food must provide the nutrients required for the life stage stated on the packaging. If you suspect a food reaction, it is better to ask a vet for advice than to keep changing recipes.

3. Underestimating the amount and cost of wet food

Wet dog food contains a large amount of water. Its stated protein content — 8 to 11%, for example — cannot be compared directly with kibble, which contains around 10% moisture. You also need to consider how many tins, trays or pouches are required each day.

If you choose mixed feeding, reduce the amount of kibble when adding wet food. The recommendations on the packaging provide a starting point; the portion should then be adjusted according to your dog’s weight, activity level and body condition.

Criteria to check before choosing

Complete food suited to your dog’s profile

Start by checking the legal designation: ‘complete food for dogs’ or equivalent wording. Complementary food, broth or a treat cannot replace main meals.

Age is just as important. Adult dog food does not necessarily meet the needs of a puppy, senior dog or highly active pet. For small breeds, the size of the pieces and energy density can make eating easier. However, a small-breed dog food formula should be chosen according to your dog’s actual weight, not solely its breed.

Ingredients list and analytical constituents

In particular, check:

  • the protein source: chicken, duck, lamb, fish or several species;
  • the levels of crude protein, fat, fibre, ash and moisture;
  • the presence of cereals, potatoes or pulses;
  • added vitamins and minerals;
  • recommendations for changing food and storage.

High-protein dog food may suit some active animals, but the stated percentage alone is not enough to assess a recipe. The portion also depends on the total energy intake, the food’s digestibility and the amount actually served.

Format, storage and changing food

A 12 kg bag means you can shop less often, but it must be stored in a cool, dry place away from light. Opened tins and trays of dog food should generally be kept in the fridge and consumed within the period stated on the packaging.

Introduce a new food gradually over around seven days, unless the manufacturer advises otherwise. This gentle transition helps limit abrupt changes in texture and composition.

Frequently asked questions about dog food

Can you mix dog kibble and wet food?

Yes, provided both products suit the same profile and are described as complete foods. Reduce the kibble portion according to the amount of wet food added to control the daily energy intake. Serve wet food at room temperature and follow the storage instructions after opening.

How long does it take to change dog food?

A gradual transition over around seven days is generally recommended for the products featured here. Mix the old and new recipes, gradually increasing the proportion of the new one. If your dog experiences persistent digestive problems, stop making successive changes and consult a vet.

Which dog food should you choose for a dog with digestive sensitivities?

Start with a clear composition, a single source of animal protein if this matches the identified need, and a weighed portion. Sensitive dog food is not a medical guarantee: reactions vary from one animal to another. If symptoms, a suspected allergy or a lasting change in appetite occurs, seek advice from an animal health professional.
