Lowest fat dog food
Every complete dog food carries a fat percentage in its analytical constituents panel, usually printed near the ingredients list, and that's the honest way to find a lower-fat option rather than trusting a marketing label alone. A lower percentage generally means fewer calories from fat per bowl, which matters for a dog who needs to manage their weight or has a fat-sensitive digestive condition.
Where to actually find the fat content
Look for the panel headed 'analytical constituents' or 'typical analysis' on the packaging — it lists protein, fat (often shown as 'oil' or 'crude fat'), fibre and ash as percentages. That panel is a legal requirement on complete pet food, so it's there on every bag whether or not the front of the pack mentions fat at all.
Comparing that percentage between foods is a more reliable way to find something genuinely lower in fat than trusting words like 'light' or 'diet' on the front, which aren't defined terms in the way the analytical panel is.
Why the percentage alone doesn't tell the whole story
A dry food and a wet food with the same fat percentage aren't delivering the same amount of fat per meal, because wet food is mostly water and dry food isn't. Comparing fat content properly means looking at it on a dry-matter or per-calorie basis rather than the raw percentage on two different formats side by side.
Portion size matters just as much as the percentage. A food with a slightly higher fat content fed in a smaller, correctly measured portion can deliver less total fat in a day than a 'low fat' food overfed, so the percentage on the bag is only half of the equation.
Who actually needs to watch fat closely
A dog who is overweight, prone to pancreatitis, or on veterinary advice to manage fat intake for another reason is the clearest case for actively choosing a lower-fat food. For a healthy dog at a good weight, fat content is one factor among several rather than the only thing worth optimising for.
If your dog has a diagnosed condition that depends on fat intake, that's a conversation for your vet, who can point you toward a specific range rather than a general 'low fat' category — some conditions need fat kept very low indeed, well below what a standard reduced-fat food offers.
What to look for across our range
Our dry and wet ranges both include recipes at different points on the fat scale, along with sensitive-formula options that tend to sit lower on fat as part of a gentler overall recipe. Checking the analytical panel on each is still the only way to compare them properly.
Whichever food you choose, weigh portions with a proper scoop or scale rather than eyeballing a bowl, since portion accuracy affects total fat and calorie intake more than most owners expect.

Common questions
- Where do I find the fat content on a dog food label?
- Look for the 'analytical constituents' or 'typical analysis' panel, usually printed near the ingredients list. It's a legal requirement on complete pet food and lists fat, alongside protein, fibre and ash, as a percentage — that's the figure to compare between foods.
- Is low-fat dog food the same as diet dog food?
- Not necessarily. 'Diet' and 'light' aren't strictly defined terms the way the analytical constituents panel is, so two foods marketed differently can have similar fat percentages. Checking the actual panel is more reliable than trusting the words on the front of the bag.
- Does my dog need a low-fat food?
- Only some dogs do — typically those managing weight, a history of pancreatitis, or another condition where a vet has specifically advised reducing fat. For a healthy dog at a good weight, fat percentage is one factor to consider rather than something to minimise by default.
- Is wet or dry food lower in fat?
- It depends on the specific recipe rather than the format itself. Wet food contains far more water, which changes how the percentage compares to a dry food, so it's worth looking at fat on a dry-matter basis if you're comparing across formats rather than the raw percentage alone.
