Choosing Dog and Cat Food in 2026: A Practical Guide to Complete Nutrition and Treats

Searching online for dog and cat food seems straightforward—until you have to choose between dozens of brands, flavours and pack sizes. Is wet food better than kibble for cats? When is puppy food suitable for your dog? And does grain-free automatically mean a product is suitable?

As a Joybuy Product Recommendation Officer, I assess product information against verifiable criteria. This helps you identify more quickly which food matches your pet’s age, size, activity level and daily routine.

Three Common Pitfalls When Choosing Dog and Cat Food

1. Mistaking a Prominent Claim for a Complete Meal

Terms such as “high protein”, “grain-free” or “made with natural ingredients” do not automatically indicate whether a product is suitable as a main food. First, check the legally required designation on the label:

• Complete pet food is intended to provide the full daily nutritional requirements for the stated animal species and life stage.
• Complementary food or a treat is not a substitute for a main meal.
• A product with a high moisture content may show less protein and fat per 100 grams than dry food. The figures are therefore not directly comparable.

For example, INABA Churu products are explicitly intended as complementary treats. According to the product information, they contain approximately 86% to 91% moisture and must not replace complete daily nutrition.

2. Looking Only at the Flavour

“Chicken”, “beef” or “salmon” on the front of the packaging does not always mean that this ingredient makes up the largest proportion. Check the full composition and the stated percentages. For example, Whiskas Adult Wet Cat Mixed Selection lists 4% beef, chicken, lamb or poultry in the relevant variant, while the broader category “meat and animal derivatives” accounts for 34%.

This is more useful information than the flavour name alone. It also helps if your cat is fussy or if you want to avoid specific ingredients.

3. Buying a Large Multipack Without Calculating Consumption

A cat food multipack can be convenient, but do not automatically choose the largest pack. Check:

• how many grams or millilitres one portion contains;
• how much your pet needs per day according to the packaging;
• how long opened wet food can be stored;
• whether your pet is already familiar with the flavour.

According to product information from various brands, opened wet food should be refrigerated and generally used within 24 to 48 hours. A smaller pack can therefore help prevent waste.

Important Parameters to Consider

1. Animal Species and Life Stage

Cat food and dog food are not interchangeable. Cats have different nutritional requirements from dogs. You should also consider the animal’s life stage:

• Puppy food is formulated for growth and is generally used from weaning until the age stated on the packaging.
• Adult dog food is intended for maintenance, with the quantity adjusted according to weight and activity level.
• Adult cat food, such as Whiskas Adult Wet Cat Food, is intended for cats aged 1 year and over.
• For senior, pregnant or medically compromised animals, consulting a vet may be advisable.

Always check the official feeding guidelines on the packaging. Requirements can vary between individual animals, even within the same breed.

2. Dry Food, Wet Food and Moisture Content

Dry dog food is easy to portion and store. Pay attention to the kibble size, particularly for small dogs. Smaller kibble can be more practical for a small jaw, while products for larger breeds often have a bigger format.

Wet cat food contains a high proportion of moisture. According to the product information, Whiskas Adult Wet Cat Food contains 84.5% moisture, while Purina ONE Sensitive Adult Wet Cat Food lists 78%. These products also provide a clear analysis of protein, fat, fibre and ash.

Wet and dry food can form part of the same feeding routine, provided you monitor the total daily amount. Combining a bag of dry food with treats without adjusting the portion can result in additional calories without you realising it.

3. Understanding “Grain-Free” in Context

Grain-free food contains no grains, but that does not automatically make it suitable for every animal. The carbohydrate source may instead come from peas, chickpeas, sweet potato or potato. Look beyond the front of the packaging:

• is the product labelled as complete food?
• is it suitable for your pet’s species, age and size?
• does it contain an ingredient your pet has previously struggled to tolerate?
• can you introduce the food gradually?

The product description for Farmina N&D Premium Chicken Puppy Small Breed lists, among other details, 36% crude protein, 22% crude fat and a grain-free composition. The manufacturer recommends transitioning over a minimum of seven days. These are verifiable product details; they do not guarantee a particular effect for every animal.

Using Treats and Complementary Food Correctly

Cat treats and dog treats are useful as rewards, but include them in the daily intake. INABA Churu lists approximately 6 kcal per tube and advises against using the treat as a substitute for complete food. The MjAMjAM Snack-Box with chicken gizzards is also classified as complementary food according to the product information and consists of 100% chicken gizzards.

When choosing treats, pay attention to three factors:

1. choose a size that is easy to portion;
2. supervise your pet while it eats;
3. always provide access to fresh drinking water.

When switching to new dog or cat food, a gradual transition over approximately seven to ten days is advisable. Monitor your pet’s stools, appetite and body condition. Stop using a product if your pet develops clear symptoms and contact a vet if problems persist.

Frequently Asked Questions About Dog and Cat Food

Is Wet Food Essential for Cats?

No. A product can be wet or dry food, provided it is labelled as complete food for the correct life stage. Wet food generally contains a high proportion of moisture, while dry food is easier to store for longer periods. The right choice depends on your cat’s preferences, your feeding routine and your ability to control portions.

How Long Does Opened Cat Food Stay Fresh?

Always follow the label. The supplied product information recommends refrigerated storage and use within a maximum of two days for several wet food products. Keep leftovers covered in the refrigerator and preferably serve them at room temperature, unless the packaging states otherwise.

Is Grain-Free Food Suitable for Every Dog or Cat?

Not automatically. Grain-free food may suit a specific preference or dietary choice, but the term alone says nothing about overall suitability. Check the animal species, life stage, composition, nutritional value and complete-food designation. If you suspect an allergy or your pet has a medical condition, professional nutritional advice is preferable to relying solely on a marketing claim.
