Choosing dry food for dogs and cats: a practical guide for adult pets

A bag of dry food for dogs and cats may seem simple to choose, but differences in age, size, ingredients and portion sizes can make a big difference. A budget-friendly pack isn’t automatically right for your pet. Equally, a long ingredients list doesn’t necessarily mean a product is a better fit.

This guide will help you tell marketing claims apart from verifiable information, so you can choose dog food or cat food with confidence.

Common pitfalls when choosing dry food

1. One prominent ingredient doesn’t tell the whole story

Words such as chicken, lamb, fish or beef on the front of the pack are designed to catch your eye. So check the full composition. For example, Iams Naturally Adult Cat Dry Food Lamb & Rice lists lamb at 4.1% and rice at 4.1%, while dried chicken and turkey appear further up the ingredients list. The product name alone doesn’t give you the full picture.

The same applies to chicken dog food, lamb dog food and fish dog food: check the percentages, the order of the ingredients and the analytical constituents.

2. Grain-free doesn’t automatically mean suitable

Grain-free dog food contains no grains, but it often includes other sources of carbohydrates, such as peas, chickpeas or sweet potato. This may suit a specific dietary preference, but it’s not a general reason to choose every grain-free product.

According to its product description, Eukanuba Grain Free Dog Adult Small/Medium Ocean Fish uses peas and gluten-free sweet potato as alternative sources of carbohydrates. If your pet has a sensitivity, always check the full label and speak to a vet about ongoing symptoms.

3. A large bag isn’t always better value

A 10, 12 or 15 kg pack may look attractively priced per kilogram. However, a large bag can be impractical if your cat or dog eats slowly. Dry food should be stored in a cool, dry place, sealed well and kept out of direct sunlight. Also check the use-by date and the recommended period for using the food after opening.

A smaller bag is often more practical if you want to try a new flavour first, or if you have several pets with different dietary needs.

Which specifications should you check?

Animal, age and size

First, choose between dry dog food and dry cat food. Cat food and dog food aren’t interchangeable as everyday meals. Then check your pet’s life stage:

  • Adult dog food is intended for adult dogs; the appropriate age can vary by product.
  • Adult cat food is intended for adult cats, often from around one year old.
  • There are separate formulas for older pets, such as Beneful Happy Adult 7+ for dogs aged seven and over.
  • For medium-breed dog food and large-breed dog food, kibble size, energy content and feeding guidelines may differ.

Always check the legal product name, intended animal and life stage on the packaging. The term complete pet food means that, according to the label, the product is formulated as a complete daily meal. Still follow the feeding guide and adjust portions for your pet’s weight, activity level and body condition.

Analytical constituents

Compare at least the following:

  • Crude protein: relevant to the overall nutritional composition, but a higher percentage isn’t necessarily needed for every pet.
  • Fat content: worth considering for less active pets or if you’re monitoring body condition.
  • Crude fibre: may be part of a formula designed to support fullness and digestion.
  • Moisture content: dry food contains little moisture, so always provide plenty of fresh drinking water.
  • Ash, calcium and phosphorus: useful figures for comparing formulas.

For example, Farmina N&D Quinoa Weight Management Adult Medium to Large Dog Food lists 34% crude protein, 12% fat and 3% crude fibre in its product information. The formula is intended for adult medium and large dogs and contains chicken, chicken meal, herring meal and quinoa. This lets you check the product specifications without treating the marketing claim as a guarantee.

Flavour and tolerance

Flavour preference is personal. Popular options include chicken dog food, lamb dog food, fish dog food, beef and combinations of these. For cats, options include tuna, chicken, lamb and beef.

Make any change gradually. Over about seven to ten days, mix a little more of the new food into the old food each day, unless the packaging gives different instructions. If your pet vomits, has persistent diarrhoea or itching, or shows a clear change in appetite, it’s sensible to ask a vet for advice.

Frequently asked questions about dry food for dogs and cats

How much dry food does an adult dog or cat need?

It depends on your pet’s weight, age and activity level, as well as the energy content of the product. Use the table on the packaging as a starting point. Ideally, weigh out portions in grams and check your pet’s body condition regularly. Treats and wet food count towards the total daily amount.

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

Follow the manufacturer’s instructions. Keep the bag tightly sealed in a cool, dry place, out of direct sunlight. For example, Iams Naturally advises resealing the pack securely after opening and using the food within six weeks. The information on your own pack takes precedence.

Is grain-free dog food necessary for a food sensitivity?

Not usually. Grain-free dog food may be an option if you want to avoid grains, but it doesn’t rule out other ingredients. If you suspect an allergy or your dog has ongoing digestive problems, it’s better to seek advice from a vet than to keep changing food yourself.
