Choosing dog and cat food: how to compare pet food without falling into marketing traps

A bag of dog or cat food may seem like a quick choice: select the animal type, flavour and pack size, and you’re done. Yet Dutch pet owners regularly pay for features that do not suit their pet’s age, activity level or body condition. Words such as “premium”, “natural” and “grain-free” can distract from the information that really matters.

As a Joybuy Product Recommendation Officer, I therefore filter the most important buying criteria: what does the label say, which animals is the food intended for, and is it complete or complementary food? This makes it much easier to compare dry food, wet food and treats with confidence.

Three common pitfalls when choosing dog and cat food

1. Premium does not automatically mean suitable

The term premium dog food says very little by itself about whether it is suitable for your dog. Start by checking the intended audience. A puppy has different nutritional needs from a senior dog. Dog food for small breeds also often differs from food for medium and large breeds in kibble size and nutritional density.

The same applies to cats. Cat food for adult cats is not automatically suitable for a neutered cat, an indoor cat or an animal with a sensitive digestive system.

2. A prominent ingredient can create an overly rosy impression

“With chicken”, “with lamb” or “with fish” does not always mean that most of the product consists of that ingredient. Check the percentage in the ingredients list. Purina One Sterilcat, for example, states 16% beef, while the composition also includes dried poultry proteins, wheat and maize.

Pedigree Dentastix for small dogs is a chicken-flavoured treat. According to the product information, it is not a complete meal but complementary food. Give this type of product alongside your pet’s usual food and adjust the main meal where necessary.

3. A functional claim is no substitute for veterinary advice

Claims about the urinary tract, digestion, joints or dental care can help you compare products, but they are not a diagnosis or treatment. According to Purina’s own research, certain formulas, for example, support the urinary tract, microbiome or weight management. This is brand information and is not a guarantee for every animal.

If symptoms persist, your pet experiences sudden weight changes, drinks very little or has problems urinating, it is sensible to consult a vet.

Check these specifications before ordering

1. Life stage, size and activity level

Pay attention to the combination of:

  • Age: puppy food, adult dog food or senior dog food.
  • Breed size: small, medium or large dog.
  • Activity level: an active dog may need a different daily amount from a calm household pet.
  • Weight and body condition: follow the feeding chart on the packaging and adjust the portion when necessary.

Eukanuba Life Care Dog Mature Small Chicken, for example, is intended for small adult dogs aged approximately 8 to 11 years. According to the product description, the senior version is aimed at small dogs aged 11 and over. This makes the age indication more important than the flavour alone.

2. Complete food or complementary food

A product labelled complete pet food is intended as a daily food when given according to the instructions on the packaging. Complementary pet food is supplementary and should not simply replace the main meal.

This distinction is especially important with wet cat food and treats. Purina One Hydralife Adult Cat Complementary Wet Food Chicken Flavor, for example, is intended as complementary food. Purina One Sensitive Adult Wet Cat Food Chicken Flavor, on the other hand, is described as complete food for adult cats.

3. Ingredients, analytical constituents and portion size

Do not compare only the ingredients. Also check:

  • the levels of protein, fat, fibre, ash and moisture;
  • the recommended daily amount;
  • the kibble size for small dogs;
  • the pack size and shelf life after opening;
  • any cereals, pulses or animal protein sources.

Grain-free dog food is not automatically necessary. It may be a preference or suit a specific dietary choice, but always check the full composition. If you suspect a food intolerance, professional advice is more appropriate than repeatedly changing your pet’s food yourself.

Frequently asked questions about dog and cat food

What is the difference between dry food and wet food?

Dry dog food is generally easy to store and simple to weigh out. Wet cat food contains plenty of moisture and may be appealing to cats that do not drink much. Always check whether the product is complete or complementary food. Combining both can be practical, provided the total daily amount and nutritional value remain balanced.

How should I switch to a different food?

Mix the new food gradually with the old one, usually over around seven days. Start with a small amount of the new food and increase it step by step. Keep an eye on your pet’s stools, appetite and body condition. If clear or persistent problems occur, it is best to stop the food and ask a vet for advice.

How long does an opened pack stay fresh?

Store dog and cat food in a cool, dry place and keep it tightly sealed. The exact shelf life after opening varies by product and is stated on the packaging. Wet food generally needs to be used sooner after opening than dry food. Also check the stated storage conditions, and always use the date and batch information shown on the label.
