Choosing dog food without falling for marketing traps: a practical guide for every dog

A bag of dog food labelled premium, grain-free or high protein can seem like an obvious choice. But an eye-catching front label tells you little about whether it’s right for your dog. A small adult dog has different needs from a fast-growing puppy, while a dog with kidney problems can’t simply eat the same food as a healthy dog.

As a Joybuy Product Recommendation Officer, I check product information against verifiable criteria. This guide shows you what to look for in dry dog food, wet dog food and specialist diets, so you can look beyond the marketing claims.

Three common dog food pitfalls

1. Mistaking a prominent ingredient claim for a complete meal

“Made with chicken”, “98% animal protein” or “grain-free dog food” may sound clear, but check the legal product description first. If it says “complete pet food” or “complete food”, it’s intended as a full meal. Complementary food shouldn’t automatically replace your dog’s main daily food.

Also check the full list of ingredients and the analytical constituents. A high protein percentage isn’t necessary for every dog and, on its own, tells you nothing about whether the food is suitable overall.

2. Ignoring your dog’s age and size

Puppy food is formulated for growth, while adult dog food is designed for maintenance. Breed size matters too. Small-breed dog food often contains smaller kibble and has a different energy content from large-breed dog food.

A large-breed puppy also needs a different feeding plan from a small adult dog. Always check the life stage, expected adult weight and feeding guidelines on the packaging.

3. Buying a diet food without advice from your vet

If your dog has symptoms or a diagnosed condition, a tailored formula matters more than a general claim such as “natural” or “hypoallergenic dog food”. You should ideally use a renal diet for dogs, such as a renal formula, in consultation with your vet. The right food depends on factors including diagnosis, blood test results, weight and medication.

What product information should you check?

1. Complete food and life stage

First, check whether the product is suitable as your dog’s main daily food. Then look for a clear indication such as:

  • puppy food for a small, medium or large dog;
  • adult dog food;
  • food for all life stages;
  • diet food for a specific medical condition.

Products with a clearly defined target group reduce the risk of buying the wrong variety. If you’re unsure, follow the feeding guidelines on the packaging.

2. Ingredients and analytical constituents

Don’t just compare the first ingredient on the list. Also check:

  • crude protein and crude fat;
  • crude fibre and moisture content;
  • calcium and phosphorus in puppy food;
  • the animal and plant protein sources used;
  • added vitamins, minerals and other additives.

Dry dog food usually contains around 8 to 12% moisture, while wet dog food often contains more than 70%. This means you can’t compare the protein and fat percentages in kibble and tinned food directly without taking the moisture content into account.

3. Portions, switching food and storage

The recommended amount is a starting point. Your dog’s weight, age, activity level and body condition will determine whether you need to adjust it. You can divide the daily portion between two meals and check your dog’s weight regularly.

Switch to a new food gradually, usually over about seven days. Store opened dry food in an airtight container in a dry place. Opened wet food should be covered, kept in the fridge and used within the time stated on the label.

Frequently asked questions about dog food

What’s the difference between dry dog food and wet dog food?

Dry dog food contains little moisture and is easy to portion and store. Wet food contains much more moisture and is often chosen for its texture or taste. Whichever type you choose, check that it’s a complete food and adjust the portion to its energy content.

How do I switch to a different dog food?

Gradually mix the new food with the old food, for example over seven days. Start with a small amount of the new food and increase it step by step. Keep an eye on your dog’s stools, appetite and weight. If symptoms persist, it’s best to speak to your vet.

How long does dog food keep once opened?

Store dry food in a cool, dry place in a tightly sealed container, and use it before the date on the packaging. Keep opened wet food covered in the fridge. Many product packs recommend using it within 48 hours or a maximum of two days; always follow the specific label.
