What's Really in
Your Dog's Food —
How to Read a Label
Most UK dog owners have never read the ingredients list on their dog's food. Here's what the terms actually mean, why they matter, and exactly what to look for when you pick up a bag.
Pick up almost any bag of mass-market dog food and turn it over. Read the ingredients list. If you know what the terms mean, you'll put it straight back on the shelf.
Most people don't know what the terms mean. That's not an accident. The pet food industry has developed a language that sounds technical and reassuring while telling you almost nothing about what's actually in the bag. This guide breaks it down.
Why the ingredients list matters more than the front of the bag
The front of a dog food bag is marketing. It shows a glossy photograph of a whole chicken, a fresh salmon fillet, a cut of beef. It says things like "natural" and "balanced" and "complete." None of that is regulated in any meaningful way.
The ingredients list on the back is where the truth is. By law, ingredients must be listed in descending order by weight before processing. The first ingredient makes up the largest proportion of the food. The last ingredient is present in the smallest amount.
If the first ingredient is a grain, a vague derivative or a cheap filler — that's what your dog is primarily eating.
Whatever appears at the top of the list makes up the biggest share of your dog's daily food. Start reading from there.
The ingredients to watch for
These appear on the labels of some of the UK's most popular and most heavily marketed dog foods. Here's what they actually mean.
This is the most common and the most misleading term in UK pet food labelling. Animal derivatives can legally include any part of any warm-blooded animal — offal, bone, fat, connective tissue — from any species, in any combination. The blend can and does change from batch to batch depending on what's cheapest and most available at the time of production. You do not know what's in it. The manufacturer doesn't need to tell you. If the label doesn't name the animal and the part, it's using this term because transparency isn't in their interest.
Another catch-all term, this time for grains. Cereals on a dog food label can mean wheat, corn, barley, oats, rye or any combination of the above — again, in proportions that vary batch to batch. Grains aren't inherently bad for dogs, but unnamed cereals are a problem because you can't assess what you're feeding. They're also a common trigger for skin irritation, loose stools and digestive inconsistency in sensitive dogs. If a brand uses this term, it's because flexibility matters more to them than transparency.
Maize (corn) is one of the cheapest carbohydrate sources available and one of the least useful for dogs. It's high-glycaemic, meaning it causes rapid spikes in blood sugar — not the steady energy that active or working dogs need. It has poor digestibility compared to sweet potato or brown rice and provides minimal usable nutrition. When you see maize listed near the top of an ingredients list, you're looking at a formula built around cost, not performance.
Meat meal isn't automatically bad. Chicken meal or salmon meal from a named source is a concentrated protein source that can be used well. Unspecified meat meal — listed simply as "meat meal" or "poultry meal" without naming the animal — is the problem. You have no idea what animal it came from, what parts were used, or whether those parts change between batches. Named meat meal is acceptable. Unnamed meat meal is a red flag.
Similar to animal derivatives in structure. Oils and fats without a named source can include any animal or vegetable fat available at the time of production. The omega ratio — which significantly affects coat condition, inflammation and joint health — varies depending on what's used. Salmon oil, sunflower oil or named vegetable oils are fine. "Oils and fats" listed without a source tells you nothing useful.
What a good ingredients list looks like
Once you know what to avoid, knowing what to look for becomes straightforward. Good dog food is easy to identify by its ingredients list — because everything on it is named, recognisable and present for a reason.
The five-second label check
You don't need to read every line of every ingredient to get a fast read on a dog food's quality. These five checks take about five seconds and tell you most of what you need to know.
Why this matters more than most people realise
A dog eating low-quality food with poor digestibility isn't dramatically sick — they're just not quite right. Slightly dull coat. Inconsistent stools. Energy that dips in the afternoon. Joints that stiffen faster than they should. Skin that itches without an obvious cause.
These signs are easy to dismiss or attribute to other things. But in most cases, nutrition is the foundation. When you get it right — named proteins, grain-free carbohydrates, clean ingredients — the difference shows up within two to four weeks. Firmer stools, better coat condition, steadier energy, improved recovery from exercise.
Dogs can't read the label. You can. That's the job.
Every piece of equipment, every decision, every input — accounted for. Working alongside dogs in Special Forces environments, I saw the same principle apply to nutrition. Weak fuel showed quickly. The dogs that performed and recovered consistently were the ones being fed with the same precision we applied to everything else. Atlantean K9 was built on that standard. Named ingredients. Known sources. Nothing vague. Nothing hidden.
What Atlantean K9 publishes on every product
Every formula in the Atlantean K9 range publishes its full ingredients list and analytical constituents on the product page. The protein source is named — British Free Range Chicken, Scottish Salmon, Angus Beef, English Country Duck. The carbohydrates are named. The oils are named. The percentages are published.
There are no animal derivatives in any Atlantean K9 formula. No unnamed cereals. No maize. No artificial colours, flavours or preservatives. The ingredients page on the website exists specifically so you can verify this yourself before you buy.
We publish what's in our food because transparency isn't a marketing position for us — it's a baseline. If you wouldn't feed it to a working dog in the field, it doesn't go in the bag.
