Buying pet products online: how to choose food and accessories without costly mistakes

Anyone looking to buy pet products online will soon find hundreds of options. However, glossy packaging, terms such as “premium” or a striking health claim do not always tell you enough. For Dutch dog and cat owners, age, size, ingredients and everyday use are particularly important.

The biggest purchasing mistakes usually stem from three pitfalls:

1. Choosing a product based on marketing language. “Grain-free”, “natural” or “premium dog food” is no guarantee that it will suit your pet. Always check the full ingredients list and the food category.
2. Ignoring age and size. Puppy food has a different nutritional purpose from food for adult dogs. A cat scratching post or dog dressing gown may also be unsuitable if the dimensions are wrong.
3. Confusing complementary food with complete food. Cat soup, cat treats and liquid snacks are often intended as supplements. They do not replace a complete main meal.

Which specifications should you check?

1. Age, size and food category

First check whether the product is intended for a puppy, kitten, adult dog or adult cat. Then check the breed or size range. A product for medium-sized dogs will not necessarily be suitable for a small or very large dog.

The label should clearly state whether the product is complete food or complementary food. Purina One Sensitive wet food, for example, is described as complete food for adult cats. Felix Soup, on the other hand, is offered as complementary food for adult cats. So use cat soup alongside a balanced main food, not as a replacement for it.

2. Ingredients and analytical constituents

Do not just compare the percentage of protein on the front of the pack. Also look at:

• the animal protein sources listed;
• fat, fibre, moisture and ash;
• the recommended daily amount;
• added vitamins and minerals;
• any ingredients your pet may be sensitive to.

With grain-free dog food, grains are often replaced with ingredients such as peas, lentils or sweet potato. This does not automatically make the product suitable for every dog. According to Eukanuba’s product information, the Grain Free Adult formula includes venison, peas and gluten-free sweet potato, among other ingredients. Introduce new food gradually and discuss persistent symptoms with a vet. A product description is not a medical assessment.

3. Dimensions, fit and care

For accessories, measurements are more important than the product photo. When buying a dog dressing gown, measure the back length according to the brand’s instructions and also check the chest measurement and fastenings. A 46 cm dressing gown is not the same as a 62 or 70 cm model.

For a cat scratching post, pay attention to the height, the width of the base, the material used for the scratching posts and the number of resting areas available. A tall tower may be appealing, but it needs to be stable and suitable for the space in your home. Also check whether the cushions can be removed and washed.

Practical tips for ordering online

• Compare the price per kilo or per portion, not just the price of the bag or box.
• Check the best-before date, batch information and storage advice for food.
• When switching dry food, do so gradually, usually over several days.
• Give treats in moderation and deduct them from the daily amount when necessary.
• Measure accessories again if your dog is still growing or has a thick coat.
• For a cat scratching post, choose a stable base and check that the sisal, cushions and toys are securely attached.

Frequently asked questions about buying pet products online

Is grain-free dog food always suitable for dogs with sensitive stomachs?

No. Grain-free simply means that grains are not included as an ingredient. The replacement ingredients can vary from one recipe to another. Check the full ingredients list and ask a vet for advice if your dog has recurring stomach or intestinal problems.

How long does opened wet food stay fresh?

Always follow the label. For the Felix and Purina products mentioned, the instructions state that opened portions should be covered and refrigerated. The permitted storage time may vary by product; discard leftovers when instructed to do so on the packaging.

What should I consider when calculating the cost of dog food?

Calculate the price per kilogram as well as the recommended daily portion. A larger bag may appear better value, but only if your dog tolerates the food well and you use it before the best-before date. With puppy food, you also need to allow for changing portions as your puppy grows.
