Choosing dog food: how to compare ingredients, life stage and nutritional value

A bag of dog food featuring words such as “premium”, “natural” or “grain-free” can quickly seem like a safe choice. However, these terms do not tell the whole story. The composition, nutritional value and suitability for your dog are more important than the front of the packaging.

The three most common pitfalls when buying dog food:

• Confusing marketing language with a nutritional guarantee: “premium dog food” is not a legally defined quality category. Check whether the product is described as complete food and review the analytical constituents.
• Looking only at the first ingredient: dog food containing chicken, lamb or fish may also contain several other protein sources. This is relevant if your dog reacts sensitively to certain ingredients.
• Overlooking life stage and size: puppy food, adult dog food and senior dog food have different nutritional aims. Kibble size and energy density can also vary for small, medium-sized and large dogs.

Which specifications are important?

1. Complete food and life stage

For everyday use, preferably choose a product described as complete food for dogs. This means that, according to the product information, it is intended to be given as the main meal. Also pay attention to the target group:

• Puppy food for growing dogs, with feeding guidance suited to their age and expected adult weight.
• Adult dog food, tailored to maintenance and activity level.
• Senior dog food, often with adjusted energy content and ingredients such as glucosamine or chondroitin. These are compositional features, not a guarantee of any medical effect.
• Food for all life stages can be practical, but always check the individual feeding guidelines on the packaging.

If your dog has health problems, food allergies or a significantly unusual weight, it is sensible to consult a vet. A product description alone is not a substitute for personalised nutritional advice.

2. Analyse protein, fat, fibre and energy

The table of analytical constituents provides a better basis for comparison than general claims. At a minimum, look at:

• Crude protein: relevant to overall protein provision, but the percentage alone does not indicate how much comes from animal ingredients.
• Crude fat: important for energy density. An active dog may have different requirements from a dog that gets little exercise.
• Crude fibre: can contribute to the texture of the food and the amount of fibre in the diet.
• Moisture content and calories: dry dog food contains little moisture and is therefore concentrated. Preferably compare portions based on the feeding guide and energy content.

According to the product information provided, Orijen Original Prey contains 38% crude protein, 18% crude fat and 12% moisture. Acana Classics Grasslands lists 27% protein, 16% fat and 12% moisture. These percentages do not automatically create a ranking; they mainly show that the formulas have been composed differently.

3. Look beyond “grain-free”

Grain-free dog food contains no grains, but usually does contain other sources of carbohydrates, such as peas, lentils, chickpeas or sweet potato. Grain-free therefore does not automatically mean that a product is easier to digest or more suitable.

When choosing dog food for sensitive dogs, it is more useful to examine the full ingredients list. Make a note of which protein sources your dog has tolerated well in the past. For example, a lamb recipe may also contain chicken or fish. According to the product description, the Eukanuba Grain Free formula with venison is offered as a grain-free recipe, with peas and sweet potato as alternative sources of carbohydrates. If you suspect an allergy, always check the packaging and discuss an elimination diet with your vet.

Claims relating to dog food with omega 3 also deserve a clear-eyed assessment. Look at the stated amount of omega 3, DHA or EPA and at the source, such as fish oil or fish ingredients. According to the product information, Orijen Original contains 1% omega 3, 0.3% DHA and 0.2% EPA. These are verifiable product specifications; they are not a medical promise.

Practical tips for buying dog food

• Compare the daily cost, not just the bag price. A 12kg bag may seem more expensive, but it can work out cheaper per meal. Calculate the price per kilogram and check the recommended portion.
• Choose a kibble size suited to your dog. Dog food for small dogs often has smaller kibble. A larger kibble may be more comfortable for medium-sized and large dogs, but chewing habits vary from one animal to another.
• Change over gradually. Mix the new food with the current food over approximately seven to ten days. Reduce or increase the portion based on weight, activity and body condition.
• Store it in a cool, dry place and keep it sealed. Seal the bag properly or use an airtight storage container. Check the best-before date on the packaging.

Frequently asked questions about dog food

What is suitable dog food for a puppy?

Choose puppy food that is clearly intended for your dog’s age and expected size. A formula for medium-sized or large puppies may have different feeding guidelines from food for small breeds. Farmina N&D Pumpkin Lamb Puppy Medi/Maxi and Eukanuba Life Care Dog Puppy Medium Chicken are examples of products specifically offered for puppies. Always follow the portion table on the label.

Is grain-free dog food better for my dog?

Not necessarily. Grain-free dog food usually replaces grains with other sources of carbohydrates. It may suit a specific dietary choice, but “grain-free” does not automatically say anything about overall nutritional value or tolerance. Compare the full composition and consider your dog’s previous reactions.

How long does an opened bag of dry dog food stay fresh?

This depends on the packaging, the product and the storage conditions. Seal the bag properly after every meal, store the food in a cool, dry place and use the best-before information on the packaging as a guide. A smaller bag may be sensible if your dog eats little or the food is used slowly.
