Dog food: how to choose the right food without being misled

Choosing dog food is about more than comparing the price per kilo or being won over by an attractive picture on the packaging. Between dry dog food, wet dog food, grain-free recipes and foods advertised as high in protein, marketing claims can quickly make it hard to know what to look for.

The key is to focus on practical criteria: your dog’s age, size and activity level, the ingredients, whether the food is complete or complementary, and how it should be stored.

Common pitfalls when buying dog food

1. Assuming “grain-free” means the food is suitable

A grain-free recipe may suit some dogs, but that label alone doesn’t tell you whether its nutritional quality is good. Grains may simply be replaced with peas, chickpeas, lentils or other sources of starch. So it’s important to look at the full ingredient list.

Grain-free wet dog food and grain-free dry dog food should also clearly state which dogs they’re intended for: puppies, adults, seniors, small breeds or large breeds.

2. Relying only on the advertised meat percentage

The advertised percentage may refer to fresh meat, offal or a range of animal-derived products. Moisture content also affects how you read the figures: wet food with around 77 to 82% moisture isn’t directly comparable with dry food containing around 12%.

For a more useful comparison, check the analytical constituents: protein, fat, fibre, ash and moisture. High-protein dog food isn’t necessarily right for every dog.

3. Overlooking whether the food is complete

A treat or complementary food shouldn’t replace your dog’s main meals. A chicken and banana bite, for example, may be intended as an occasional treat or a supplement, even if it contains 20% protein.

If the food is intended to make up your dog’s daily diet, look for the words “complete pet food for dogs”. If your dog has food sensitivities or is under veterinary care, ask a professional to check the ingredients before changing their diet.

What to check before you order

Age, weight and activity level

Food for adult dogs won’t meet the same needs as a puppy recipe. Similarly, a formula for active dogs may have a very different energy density from one designed for a more sedentary pet.

For a large dog, check:

  • the weight and size range shown on the packaging;
  • the recommended daily amount, in grams or tins;
  • whether there’s a feeding guide for low, moderate or high activity levels;
  • the size of the kibble or bites.

These quantities are guidelines only. Adjust them to suit your dog’s weight, body condition and actual activity level.

Ingredients and analytical constituents

The order in which ingredients are listed gives you an initial indication, but it’s worth checking it against the analytical composition table. Look for:

  • crude protein;
  • crude fat;
  • crude fibre;
  • crude ash;
  • moisture;
  • declared minerals and nutritional additives.

Wet dog food generally contains much more water than dry food. It can be served on its own if it’s a complete food, or included in a mixed diet, provided you reduce the amount of dry food accordingly.

Storage and transition

Once opened, most wet foods should be kept in the fridge and used within the period stated on the label, often within 48 hours. Unopened tins and pouches should be stored somewhere cool, dry and out of direct sunlight.

To help prevent digestive upsets, introduce new food gradually over several days. Always leave a bowl of fresh water within your dog’s reach.

Treats: a little goes a long way

Dog treats can help with training or reward good behaviour, but they should only be given occasionally. Check the recommended serving, fat content and whether the product is labelled as a “complementary pet food”.

For example, MeatyWay chicken and sweet potato strips are advertised as grain-free, with at least 20% crude protein and 5% fat. They should be given alongside meals, under supervision, with fresh water available. If your dog is sensitive, introduce each new treat separately to check that they tolerate it well.

Dog food FAQs

Dry or wet dog food: which should you choose?

Dry food is easy to store and measure out. Wet food provides more moisture and adds variety to mealtimes. The right choice depends on whether the product is complete, your dog’s needs and what works for your routine. You can combine the two, as long as you adjust the quantities.

How long can you keep an opened tin?

Transfer the food to a sealed container and store it in the fridge, following the storage period shown on the label. Several products featured here recommend using the food within 48 hours, or within two days of opening. You can serve wet food at room temperature if your dog prefers it that way.

How can you change your dog’s food without upsetting their digestion?

Gradually mix the old and new foods over several days, increasing the proportion of the new recipe a little at a time. Keep an eye on your dog’s appetite, stools and weight. If a reaction persists, ask your vet for advice before continuing the transition.
