Choosing grain-free dog food: a practical guide for adult dogs

Grain-free dog food may seem easy to choose at first glance. However, attractive packaging can hide important details. Your dog may do well on a grain-free recipe, for example, but not so well with a particular protein source, a high fat content or a kibble size that is too large.

These three pitfalls are common:

  1. “Grain-free” is mistaken for automatically being suitable for every dog. Grain-free dog food often contains peas, chickpeas or sweet potato as an alternative source of carbohydrates. These ingredients may not suit some dogs either.
  2. Meat marketing claims are not checked. Look at the full ingredients list and the percentage of each animal source. “With chicken” tells you less than a specific percentage of chicken, dried chicken or fish.
  3. The pack size does not match how much you use. A 12 kg bag may seem good value, but it is not always practical for a small dog or a household that likes to rotate flavours. Once opened, dry food should also be kept sealed and stored somewhere dry.

What to look for in grain-free dog food

1. Check whether it is a complete food

For adult dogs, complete food is important if it is being served as their main meal. The label usually states which life stage and breed size the product is intended for. Complementary wet food or a pure meat product does not necessarily contain all the nutrients your dog needs.

Also check:

  • the recommended daily amount;
  • your dog’s weight and activity level;
  • the analytical constituents, such as crude protein, fat, fibre and crude ash;
  • whether added vitamins and minerals are included.

A higher protein percentage does not automatically mean the food is better suited to your dog. A calm adult dog may have different energy needs from an active working dog.

2. Look beyond the front of the pack

When choosing high-meat dog food, the order of the ingredients matters. Ingredients are usually listed in descending order. Check that the protein source is clearly identified, for example chicken, lamb, game or fish.

For a dog with food sensitivities, a recipe with one clearly identified animal protein source may be easier to assess. This does not guarantee that symptoms will disappear. If your dog has persistent itching, digestive problems or other symptoms, it is best to speak to a vet.

Also be wary of terms such as “natural” or “premium dog food”. They are no substitute for information you can check. Look at the ingredients, nutritional values, net quantity and feeding instructions.

3. Match the kibble, protein source and size to your dog

Dry dog food is easy to portion and store. The kibble size should still suit your dog’s jaw and eating habits. A mini version may be more convenient for small breeds. Larger packs are often available for medium and large breeds, which can mean a lower price per kilogram.

Wet dog food typically has a high moisture content and may appeal to fussy eaters. Check whether the product is a complete food or intended as a complementary food. Once opened, a tin or tray should be kept in the fridge in accordance with the instructions on the pack.

When changing foods, a gradual transition over about seven days is a practical approach. Mix a little more of the new food with the old each day and keep an eye on how your dog responds.

Frequently asked questions about grain-free dog food

Is grain-free dog food necessary for every dog?

No. Some adult dogs do well on dog food that contains grains. Grain-free dog food can be a practical choice if you want to avoid grains or are looking for a recipe with a different source of carbohydrates. If you suspect a food allergy, your vet is the right person to speak to.

Is grain-free dog food suitable for sensitive dogs?

It depends on the full ingredients list. A grain-free recipe may still contain several protein sources, peas or other ingredients that your dog reacts to. Look for a clear label and introduce new food gradually.

Is dry dog food better value than wet food?

That depends on the brand, energy content, portion size and pack size. A large bag of dry food may cost less per kilogram, while wet food is handy for portion control and adding moisture to a meal. Compare the recommended daily portion rather than just the shelf price.
