Buying dog and cat food online: how to choose the right food without falling into marketing traps

Anyone looking to buy dog and cat food online will soon come across hundreds of options. Dry food, wet food, grain-free dog food, puppy food, treats and food for sterilised cats differ in more than just flavour and packaging. Suitability for age, size and activity level also plays a role.

However, attractive packaging does not tell you everything. So first, look out for the following common pitfalls.

Three pitfalls when buying pet food online

1. A flavour name reveals little about the ingredients

A package may say “chicken dog food” or “chicken cat food”, even though chicken makes up only a small part of the recipe. So check the ingredients list and the percentages. For example, Felix Double the Tasty Beef and Chicken states that beef and chicken each make up 2% of certain kibbles. The name therefore mainly describes the flavour variety, not necessarily the main ingredient.

2. A treat is not a complete meal

Not every product containing nutrients is complete and balanced pet food. According to the product information, INABA Fun Bites Dog Chicken Wraps is complementary food for dogs. The treat contains 82% moisture and is intended as a reward, not as a replacement for a complete meal.

So give dog biscuits and dog treats alongside your pet’s daily food and adjust the total amount accordingly. This prevents extras from unknowingly making up a large proportion of your pet’s daily energy intake.

3. “Grain-free” or “premium” is not a universal selection criterion

Grain-free dog food may suit a specific preference, but grain-free does not automatically mean that the food is suitable for every dog. Age, body weight and activity level remain important too. The same applies to the search term premium dog food: look at the full composition, analytical constituents, feeding instructions and suitability for the relevant life stage.

If your pet has symptoms, a food intolerance or a medical condition, consulting a vet is wiser than relying solely on marketing claims.

Which specifications should you check before ordering?

1. Check the life stage and animal type

Choose food that is clearly intended for:

  • puppies or kittens;
  • adult dogs or adult cats;
  • sterilised or neutered cats;
  • small, medium-sized or large dogs;
  • all life stages, when this is explicitly stated on the label.

Puppy food often contains different nutritional ratios from food for adult dogs. According to the product information, Purina One Junior Kitten Food Chicken & Grain Formula is intended for kittens from weaning up to 12 months, as well as pregnant or nursing cats. For an adult cat, cat food for adult cats is the more logical choice.

2. Look for “complete food” and the nutritional analysis

The legal product description on the packaging helps distinguish between complete and complementary food. Complete food is intended to be given as a daily meal in accordance with the instructions. Also check, among other things:

  • crude protein;
  • fat content;
  • crude fibre;
  • crude ash;
  • moisture content;
  • added vitamins and minerals.

Do not compare wet and dry food solely on the basis of their protein percentage. Wet food contains much more moisture, meaning that percentages can differ depending on the basis used for calculation. CESAR Classic Wet Dog Food Chicken is a complete wet food for adult dogs. The packaging contains 150 grams and states, among other things, 10% protein, 5% fat and 81% moisture.

3. Match the packaging and portion size to your household

A large bag can be cost-effective if you have several dogs, but only if you can seal the food properly and use it before the best-before date. For a small dog or cat, an 800-gram pack may sometimes be more practical for maintaining freshness and variety.

Always follow the feeding table on the packaging. The recommended amount may vary depending on body weight, age, activity level and body condition. Also make sure your pet always has access to clean, fresh drinking water.

Frequently asked questions about buying dog and cat food online

Which is better value: dry food or wet food?

That depends on the portion size, packaging and composition. Dry dog food often has a longer shelf life once opened and is easy to weigh out. Wet food contains more moisture, but individual portions may work out more expensive per gram. Compare the price per kilogram, not just the price per pack.

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

Store dry food in a cool, dry place in a sealed container or properly closed bag. Close the bag securely after each use and follow the storage information on the packaging. Opened wet food should generally be refrigerated. CESAR states that it can be kept in the fridge for a maximum of two days; INABA recommends using opened packs within 24 hours.

Which food is suitable for a sterilised cat?

Choose a product labelled as intended for sterilised or neutered adult cats. Then follow the feeding table and monitor your cat’s body condition. Purina One Sterilcat is an example of food designed for this specific target group. If your cat gains noticeable weight or develops other problems, a vet can help create a suitable feeding plan.
