Choosing dog food: how to compare ingredients, size and nutritional needs

A bag of dog food labelled “premium”, “natural” or “grain-free” can seem like an obvious choice. But an eye-catching front label tells you little about whether it’s right for your dog. The best choice depends mainly on your dog’s life stage, size, activity level, the food’s ingredients and how you plan to use it.

Common mistakes when buying dog food

1. Assuming grain-free means it’s automatically more suitable

Grain-free dog food contains no grains, but that doesn’t mean every dog needs it. Instead of grains, manufacturers may use ingredients such as peas, chickpeas, sweet potato or quinoa as a source of carbohydrates. Always check the full ingredients list and make sure the food is suitable for your dog.

2. A high protein percentage doesn’t tell the whole story

A high crude protein percentage may appeal if you have an active dog, but the source of that protein matters just as much. Check whether the animal ingredients are clearly listed, such as salmon, duck, venison, cod or poultry. Also look at the fat content and recommended daily amount.

3. A large pack isn’t always better value

Once opened, dry dog food is most practical when the bag can be resealed properly and is stored somewhere cool and dry. However, a 12 or 14.5 kg bag may stay open for a long time if you have a small dog. This can affect how appealing the food is. Opened wet dog food, on the other hand, needs to be used within a short period and usually kept in the fridge.

Which specifications should you check?

1. Life stage and dog size

The packaging should clearly state which life stage the food is intended for. Adult dogs have different nutritional needs from puppies and senior dogs. Kibble size may also be relevant.

  • Small dogs: choose a variety specifically labelled for small breeds or mini-sized dogs.
  • Medium and large dogs: check whether the product is intended for medium/maxi breeds.
  • All breeds: some formulas are suitable for adult dogs of different sizes, but you should still check the feeding guide.

A product sold as complete and balanced dog food should be suitable as a main diet when fed according to the information on the label. Always follow the European labelling information and feeding guidelines on the packaging.

2. Protein source and ingredient order

Ingredients are generally listed in descending order by weight, so check which ones appear first. Dog food containing game, for example, may list venison, wild boar or reindeer. Fish-based dog food often includes salmon, cod, herring or sea bass.

A single animal protein source can make it easier to see what’s in the food if you want to avoid certain ingredients. However, that doesn’t automatically make it hypoallergenic dog food. If you suspect a food allergy or your dog has ongoing symptoms, it’s a good idea to speak to a vet.

3. Analytical constituents and practical portions

Compare at least:

  • crude protein;
  • crude fat;
  • crude fibre;
  • moisture content;
  • calcium and phosphorus, if this information is provided;
  • the recommended amount for your dog’s body weight.

Dry kibble contains little moisture, while wet food has a much higher moisture content. This means you can’t compare protein and fat percentages in dry and wet food like for like without taking moisture content into account.

Dry food, wet food or a combination?

Dry dog food is easy to portion and often practical for everyday use. Seal the bag securely after use and use a measuring cup or kitchen scales to avoid overfeeding.

Wet dog food contains more moisture and may appeal to dogs that prefer soft food. Check whether it’s a complete food or a complementary food. Once opened, it should be kept in the fridge according to the label.

You can combine the two, but adjust the total amount. Don’t serve the full recommended portion of dry food as well as the full portion of wet food. When introducing a new product, switch over gradually – for example, over about seven days – to make the transition easier to manage.

Extra care for dogs with sensitivities

If your dog has food sensitivities, it’s important to note down the protein sources and all the animal ingredients. A formula containing game, fish or one clearly named protein source can make it easier to compare products, but “hypoallergenic” isn’t a guarantee that it will suit every dog.

Also check for ingredients such as fish oil, sources of fibre, prebiotics and grains. According to brands’ own product information, these ingredients may support particular nutritional goals, such as skin, coat or digestion. Don’t treat these statements as medical claims. If your dog has itching, digestive problems or other ongoing symptoms, a vet should advise on the right approach.

Frequently asked questions about dog food

How long can you keep an opened bag of dog food?

That depends on the product and packaging. Seal dry food securely after each use, store it somewhere cool and dry, and follow the best-before date on the bag. Wet food generally needs to be refrigerated after opening and used within the period stated on the label.

How do you switch to a different dog food?

Gradually mix the new food with the old food. Start with a small proportion of the new food and increase it over about seven days. Keep an eye on your dog’s appetite, stools and behaviour. If you notice any clear problems, you can pause the transition and ask a vet for advice.

How much does dog food cost per month?

Monthly costs depend on your dog’s body weight, activity level, the food’s energy content, portion size and pack size. So don’t compare only the price per bag: work out the price per kilogram as well as the daily amount according to the feeding guide. This gives you a more realistic idea of the cost of feeding your dog.
