Calories get mentioned a lot. But ask most owners what a calorie actually does in a dog’s body, and you will usually get a blank stare. This is where the confusion begins. People then latch onto calorie-counting like it is the secret to health. But without understanding how calories interact with the organs, it becomes a trap. Owners begin to cut back, or switch food, or panic about labels, yet never realise that overload, not just overfeeding, is doing the damage. So let us strip it back, keep it simple, and link every number back to the one thing that matters, protecting the dog’s biology, not pleasing the bag., and you’ll get a blank stare. So, let’s change that. This blog is simple, direct, and backed by biology.
Most latch onto this subject like a boa constrictor preparing its next meal. But chasing calories can be like finding a pot of gold at the end of the rainbow, only to discover it is empty. It often leads to confusion and disappointment.
🔍 What Is a Calorie?
A calorie is just a unit of energy. Your dog burns calories:
- when it breathes
- when it walks
- when it sleeps
- when it plays
That energy keeps the heart beating, muscles working, and brain firing. If the dog eats more calories than it burns, it stores the excess as fat. Eat less than it burns, and it starts using stored energy instead.
So yes, calories matter. But focusing only on calories, without understanding where they come from or how your dog burns them, creates problems.
🍗 Are Calories from Meat Bad?
No. In fact, meat-based calories are some of the best. They come with amino acids, fats, vitamins, and minerals that actually build the body, not just fill it.
Some people ask if chicken has fewer calories than beef, or if lamb is more fattening than salmon. In truth, these differences are tiny. The real issue is the volume of food, not the meat type.
So, the better question is: “Am I feeding the right amount for my dog’s ideal weight and lifestyle?”
🧠 Why the Calorie Count Alone Doesn’t Work
- Let’s say you have two dogs:
- both weigh 20kg
both eat 900 calories a day
But one dog runs for an hour every day and the other sleeps 20 hours a day.
Clearly, those two dogs need different plans. One burns energy. One stores it. The food might be identical, but the results will not be.
🐾 And now picture a lazy office dog, curled up under the desk, barely moving from 9 to 5. Then home for tea and cuddles on the sofa. Compare that with a dog out herding, scent training, or even doing agility twice a week. You cannot expect the same result from the same calorie count. You will be disappointed.
Once people realise it is a unit of energy, they often start focusing on reduction. That is not a bad thing, and this effort would be better spent refining the food, not just the numbers. But this is where many owners go wrong. They assume that reducing calories will make life easier. It is not that simple.
Often, we have found that owners who do this later seek help because their dog appears lethargic, low energy, or flat in mood. Do you see the problem? Yes, you got it — it is the owner. Always aiming too high or too low. Never aiming for balance. Unless the bag says it. Then suddenly, they trust the bag. The same bag they were questioning five minutes ago.
The problem is not the calorie. It is the habit of shooting from the hip, trying to outsmart biology, while unknowingly creating chaos.
🚶♂️ One of the Smartest Replies to Calorie Worries
"Walk your dog more."
It is not meant to offend, it is a factual, biological reply.
Because dogs burn calories through movement, not maths. Their organs respond to discipline, not just diet labels. So yes, calories count. But what your dog does after the bowl is empty often matters more.
🐶 Imagine a typical 5-year-old family dog who gets a morning stroll to the lamppost, a few biscuits, spends the day on the sofa, and then eats again in the evening. Calories are going in, but barely being used. Weight creeps up, organs get sluggish, and energy drops. Not from lack of love, but from lack of understanding.
So walk your dog more. Let nature do what it was built to do, and your dog will thank you with years of better health.
📏 A Simple Dog Calorie Calculator (Guideline Only)
Most canine nutritionists use this base calculation:
Resting Energy Requirement (RER) = 70 x (Body weight in kg)^0.75
Then multiply by a factor depending on activity:
1.2 for neutered, inactive dogs
1.4–1.6 for average dogs
1.8–2.0 for active dogs
2.5+ for working or highly active dogs
Example:
A 20kg neutered dog would have:
RER = 662 kcal/day
Daily calories = 662 x 1.4 = 926.8 kcal/day
This is a guide. You always adjust based on progress, not prediction.
🍽 How Calories Relate to Dog Food
Every dog food has a calorie value per 100g or per cup. This is called Metabolisable Energy (ME) and it should be listed on the packaging. For example:
- A high-meat food might contain 380–420 kcal per 100g
- A lower quality kibble might be 320–350 kcal per 100g
That means if your dog needs 926 kcal per day, and your food is 400 kcal per 100g, you would feed:
926 ÷ 400 = 2.3 x 100g = 230g total per day
This makes feeding plans clearer, but only if the food has clear labelling. If not, it is harder to calculate and adjust.
And remember: the better the food, the more “useful” calories your dog receives. Cheap filler calories can bloat the belly, but still starve the organs.
Would you be right in thinking the amounts printed on the bag do all this calculation for you? Yes. That is exactly what they are for. But this is where things get interesting, because most owners ignore that part.
The most accurate and useful section on the bag is the one people trust the least. Do you see what a mess the dog food world is in?
⚠️ However — Do Not Let Calories Distract You
Here is the uncomfortable truth: calories are not the UK’s biggest nutrition problem. Overload is.
Most dogs are not just fed too much; they are fed too many additives. Too many minerals. Too many vitamins. Too many extras. So even when the calories are correct, the organs are overwhelmed.
The real battle is not just managing calories. It is protecting the organs from toxic overload.
And that is why we made our food the way we did. We did not chase calorie numbers. We tracked what actually worked inside real dogs over time. What supported energy. What kept organs stable. What improved bloods. And what made owners say, “my dog feels amazing.”
🧪 Backed by Biology (And Respected Organisations)
FEDIAF (the European Pet Food Industry Federation) uses similar methods for calorie guidelines across Europe. They base their values on decades of feeding trials, metabolic studies, and nutrient targets. Their full technical nutritional tables are free to download.
The PDSA and WSAVA also support calorie-controlled feeding based on body condition and lifestyle, not just what the label says.
🧠 Final Word
Calories can help you guide the journey but they are not the journey itself. They are just one piece of the puzzle. The real win is protecting the soft, fragile organs from slow internal collapse. That is the journey. And most people never even realise they are on it.
Watch the waist. Weigh the dog. Track the energy. Feed to the ideal weight. Protect the organs.
And if in doubt: walk your dog more.
