Choosing the right food for your dog can feel confusing, especially when every packet seems to highlight different ingredients, nutritional benefits and feeding recommendations. With so much information to take in, knowing what actually matters can make the decision much easier.
Learning how to read a dog food label helps you understand what your dog is eating, whether the food suits their life stage and how much they should be having each day. It also helps you look beyond marketing claims and focus on the information that really matters.
From understanding dog food ingredients to working out daily portions, this guide covers the key things to look for when choosing a food and making sure your dog gets the nutrition they need.
What Should You Check First on a Dog Food Label?
Before looking closely at the ingredients, check whether the food is suitable as your dog's main diet and whether it's intended for their life stage.
What Does Complete Dog Food Mean?
A complete dog food is formulated to provide all the nutrients your dog needs when fed as directed, without requiring another food to make up their daily nutritional requirements. Check that it's suitable for your dog's life stage too, as puppies and adult dogs have different nutritional needs.
What Is Complementary Dog Food?
A complementary dog food is intended to be fed alongside other food rather than providing a complete daily diet on its own. This category can include certain treats, toppers and products designed to accompany a complete food.
Complementary foods can be part of your dog's routine, provided you follow the instructions and account for any additional calories. Look for the words "complete" or "complementary" on the label so you know how the product should fit into your dog's diet.
How to Read Dog Food Ingredients: What Should You Look For?
The ingredients list tells you which ingredients are used in the recipe and can help you understand the food's overall composition.
Start With the Main Ingredients
Dog food ingredients are generally listed in descending order by weight when they're added to the recipe. Ingredients nearer the beginning therefore make up a larger proportion by weight at that stage.
You'll often see protein sources such as chicken, lamb, beef or fish, alongside carbohydrate sources, fibre-rich ingredients and fats or oils. Fish oil, for example, provides omega-3 fatty acids, which have important roles in your dog's body.
However, ingredient order doesn't tell you everything about nutritional quality. Fresh meat contains water, so its weight before processing doesn't necessarily reflect how much it contributes once the food is prepared. Consider the complete recipe rather than judging a product by its first ingredient alone.
UK dog food labels may list ingredients individually or use recognised category names, such as "meat and animal derivatives", "cereals" or "derivatives of vegetable origin". These are accepted labelling descriptions and don't automatically mean a food is lower quality. Look at the overall formulation and whether it provides suitable nutrition for your dog.
You might also notice ingredients highlighted on the packaging, such as "with chicken". Where a product makes a specific claim about an ingredient, you may see a percentage showing how much is included.
Understand Carbohydrates, Fibre and Functional Ingredients
Protein often gets plenty of attention, but other nutrients and ingredients also play important roles in a balanced diet. Carbohydrate sources, including rice, oats and potato, provide energy. Fibre contributes to normal digestive function, while fats supply energy and essential fatty acids.
You may also see functional ingredients such as fish oils and prebiotic fibre, alongside nutritional additives such as vitamins and minerals. Depending on the formulation, these can contribute to skin and coat condition, digestive function and the maintenance of normal bodily processes.

Look Beyond Marketing Claims
Words such as "natural", "grain-free" and "premium" can attract attention, but they don't tell you the whole story. Grain-free doesn't automatically mean a food is healthier or more nutritious.
Rather than choosing food based on headline claims, consider whether it's complete, appropriate for your dog's life stage and suited to their needs. If your dog has a suspected food intolerance or medical condition, speak to your vet before choosing a specialised diet.
Understanding the Nutritional Information on a Dog Food Label
The analytical constituents section provides percentages that help you understand the food's composition. The main terms are:
Crude protein: Indicates protein content. Protein helps maintain and build body tissues, although the percentage alone doesn't tell you everything about its quality or digestibility.
Crude oils and fats: Shows the fat content. Fats provide concentrated energy and essential fatty acids that contribute to normal bodily functions, including maintaining healthy skin and coat.
Crude fibre: Indicates fibre content, which can help support digestive function.
Crude ash: Indicates the food's mineral content. It's measured by burning a food sample and analysing the residue left behind; it doesn't mean ash has been added as an ingredient.
Moisture: Shows how much water the food contains, which is particularly useful when comparing wet and dry foods. Under UK labelling rules, moisture must be declared when it exceeds 14%.
The word "crude" is a technical labelling term used to describe the analytical measurements, rather than an indication of food quality. You may also find nutritional additives, including vitamins and minerals, listed separately.
Manufacturers may provide energy or calorie information, usually in kilocalories (kcal). This can help you understand how much energy a portion provides and calculate feeding amounts, but it isn't part of the standard mandatory analytical constituents declaration and may not appear on every product.
Don't judge a diet by one number alone. A higher protein percentage doesn't automatically mean a food is more suitable for your dog. Moisture is also important when comparing wet and dry food: wet food contains substantially more water, while dry food is more concentrated. Their nutrient percentages can therefore look very different, even when both are complete foods. For a fairer comparison, take moisture content into account and compare energy content too, where available.
How Much Food Should You Feed Your Dog Each Day?
The label can help you work out how much to feed, but your dog's needs depend on more than weight alone.
Use the Feeding Guidelines as a Starting Point
Most dog foods include a feeding chart with a recommended daily amount based on factors such as body weight and life stage. These guidelines are a starting point, not fixed rules for every dog.
Two dogs of the same size can have different energy requirements because of their activity, metabolism and body condition. Start with the instructions for the specific food, then monitor your dog and adjust as needed. Your vet can help establish a suitable target weight if you're unsure.
Consider Age, Size, Activity and Body Condition
Several factors influence your dog's daily allowance:
Age: Puppies need nutrition to support growth. Adults generally need enough energy to maintain a healthy body condition, while older dogs may need adjustments as activity and health change.
Size and weight: Current weight helps you use the feeding chart, but ideal weight matters too. A dog carrying excess weight shouldn't automatically receive a larger portion because they're currently heavier. Your vet can help establish a target weight and feeding plan where weight loss is needed.
Activity level: An active dog may need more energy than one with a more sedentary routine. Breed and size alone won't tell you exactly how much an individual dog needs.
Your Dog's Profile: Look at your dog from above and from the side. Ideally, they should have a visible waist and abdominal tuck, with ribs you can feel without pressing firmly. These checks can help you spot changes that the scales alone might not show.
Adjust for Wet, Dry or Mixed Feeding
Dry dog food contains less moisture and is generally more energy-dense by weight than wet food, so recommended daily amounts can look quite different.
Whether you prefer kibble or the higher moisture content of wet food, Calibra offers options to suit different feeding preferences. Explore our dry dog food range and wet dog food range.
Mixed feeding can work too, provided you account for both foods in your dog's daily allowance. Check the feeding instructions for each product and look for the manufacturer's mixed-feeding recommendations. Adjust portions to account for the energy supplied by each food, rather than replacing the same weight of one with the other. Where guidance isn't clear, feel free to get in touch with our team for expert advice or ask your vet.
Weigh Portions, Account for Treats and Monitor Progress
Use kitchen scales to weigh your dog's food rather than estimating portions by eye or relying on a scoop. This keeps portions consistent and makes adjustments easier.
The recommended daily amount is the total for the day, not the amount for each meal. Remember to account for treats, chews and training rewards, as these contribute to daily calorie intake. As a general guide, treats should make up no more than 10% of your dog's daily calories, with the rest coming from their complete food. You may need to reduce meal portions to allow for extras.
Regularly monitor your dog's weight and body condition, as well as their appetite, energy levels and stool quality. Persistent digestive changes or unexplained weight gain or loss should be discussed with your vet rather than simply addressed by changing food portions.
Do Puppies, Adult Dogs and Senior Dogs Need Different Amounts?
A dog's nutritional needs change throughout life, so choose food and portions that reflect their current stage.
Feeding Puppies
Puppies need a complete food formulated for growth, with the nutrients and energy to support development. Their requirements change as they grow, so review portions regularly. Puppies may also need smaller, more frequent meals than adult dogs. Monitor their growth and body condition rather than continually increasing portions because they seem hungry. Your vet can help check they're developing at a healthy rate, particularly if they're expected to become a large dog.
Feeding Adult Dogs
Once fully grown, the focus shifts to maintaining a healthy weight and providing enough energy for everyday life. Allowances still depend on activity, body condition and individual needs. Changes such as reduced exercise or neutering may mean portions need reviewing. Explore Calibra's adult dog food range for options suited to this life stage.
Feeding Senior Dogs
Older dogs may experience changes in activity, appetite, digestion and body condition. Some become less active and need less energy, while others may struggle to maintain weight or have health conditions that affect their nutritional needs. Don't automatically reduce portions just because your dog is getting older. Monitor their weight and eating habits, try a food specially formulated to support senior dogs to get all the nourishment they need, and speak to your vet if you notice changes or are unsure whether their food remains suitable.
When Should You Speak to Your Vet About Your Dog's Diet?
Feeding charts and ingredient lists can't account for every dog's individual health needs. If your dog needs to lose weight, struggles to maintain weight or experiences rapid or unexplained changes, your vet can help establish an appropriate feeding plan. Seek advice too if your dog is unwell, has ongoing digestive problems or develops a persistent change in appetite.
Some medical conditions may require a specially formulated diet. Explore Calibra's veterinary diets for dogs if your vet has recommended a specialised food. Don't make drastic portion changes or switch to a therapeutic diet without appropriate advice.
Your Quick Dog Food Label Checklist
- Before choosing a food or measuring your dog's next meal, ask:
- Is it intended for dogs and suitable for their life stage?
- Is it labelled complete or complementary?
- Have you checked the ingredients and nutritional information?
- Does it suit your dog's activity level and body condition?
- Are you following the product's feeding guidance?
- Are you weighing portions, accounting for treats and monitoring your dog's condition?
These simple checks can make everyday feeding more straightforward and help you feel more confident about your choices.
Final Thoughts
Learning how to read a dog food label doesn't have to be complicated. Check whether the food is complete, understand what the ingredients and nutritional figures tell you, and use the feeding chart as a starting point. Monitor your dog's condition and speak to your vet when health or weight concerns arise.
