The Prey Principle in Dog Snacks – what it is, and what it isn't

By Mutti | Updated April 2026

There’s that moment in the dog food aisle when you turn over a package and wonder: what does this actually have to do with what a dog would naturally eat? It says "Premium snack with carrot, sweet potato, apple, and a hint of salmon." And you think: salmon is okay. My dog wouldn't willingly hunt the rest of it outside.

This is where the Prey Animal Principle comes in. It's not a trendy marketing term, but a simple question: what would be logical if you based it on what dogs would biologically eat? And what is just filler with good PR copy?

In short: The Prey Animal Principle describes a feeding logic that is based on what a dog would eat in nature as prey – predominantly meat, no sweets, no grain fillers. For snacks, this means: a short ingredient list, clearly named meat, no additives that only improve the label's appearance. It's not a religion or a full BARF program, but a practical standard when shopping.

What the Prey Animal Principle really means

Dogs are descended from wolves and are biologically oriented towards a meat-based diet. This doesn't mean they can't tolerate anything else – dogs have become astonishingly adaptable over millennia, and a little rice in their bowl won't kill them. But the basic logic of their digestion is that of a carnivore, not an omnivore like us.

The Prey Animal Principle turns this observation into a rule of thumb for food and snacks: what would be logical for the dog as prey? Answer: an animal. With muscle meat, offal, bones, tendons. Not: corn, sugar, artificial flavors.

Translated to a snack, this means: if meat is central, clearly declared, and not surrounded by additives that wouldn't be found in prey – then the snack is close to the principle. If grain flour is the main ingredient and meat only appears as a flavor, the snack is far from the principle.

As simple as that sounds, it is rarely consistently implemented in the market. That's precisely why it's worth taking a conscious look at the back of the packaging.

Why this is not the same as BARF

Here's an important clarification, as it often gets confused: The Prey Animal Principle and BARF are related, but not identical.

BARF (Biologically Appropriate Raw Food) is a complete nutritional concept – daily, calculated, with bones, offal, supplements. The Prey Animal Principle is the logic behind it, which you can also apply to individual components of a normal feeding routine.

So, you don't have to feed BARF to think according to the Prey Animal Principle. You can feed dry food as the main meal and still choose snacks that follow the logic – i.e., pure meat without frills. This is not a contradiction, but a pragmatic middle ground.

What a "prey animal-like" snack fulfills

I find lists practical because they shorten discussions. Here's my standard when shopping:

An ingredient list that you understand at first glance is usually closer to the principle than one where you have to Google what's actually in it. That's trivial, but it works.

Mutti's Moment: How I handle it in everyday life

For Emil, I do it like this: For snacks, I strictly follow the Prey Animal Principle. Training cubes made of pure horse, trachea, dried beef, sometimes a tendon. What he gets as a reward or for occupation has an ingredient list of at most two lines. That's my guiding principle.

For the main meal, I'm more pragmatic. He gets high-quality dry food with clear declarations and occasionally fresh meat – not pure BARF, because the effort for a calculated raw feeding is too much for me in everyday life. This isn't "by the book," but it's the line I can consistently maintain.

And honestly: a maintained pragmatic middle ground is worth more than a perfect concept that collapses after three months because there's no time left. I don't believe in striving for ideals that don't work in everyday life.

Who benefits most from this

The Prey Animal Principle is not equally important for every dog. For an uncomplicated, healthy dog that tolerates everything, it's a good guide, but not a must. However, there are groups that benefit significantly from it:

Sensitive and allergic dogs – because fewer and clearer ingredients mean fewer variables. A dog that reacts to poultry can work clearly with a monoprotein horse snack. With "meat and animal by-products," they are in the dark.

Dogs with sensitive digestion – because pure, gently processed meat is often better tolerated than highly processed mixed products with sugar, binders, and flavorings.

Seniors – because digestion becomes more sensitive with age, and simple recipes cause fewer problems.

Dogs that receive many snacks – because with frequent feeding, the quality of each individual piece adds up. If you give ten snacks a day, you should be sure what's in them.

Where the principle reaches its limits

So that I don't get carried away with praise – a few honest limitations.

The Prey Animal Principle is a logic, not a panacea. Even a perfectly principle-abiding snack can be the wrong choice for your dog if they don't tolerate the protein source, if the format doesn't fit their mouth size, or if the amount is too high.

Furthermore: pure meat is usually more expensive than diluted standard products. Those with a limited budget have to weigh "less, but better" against "more, but average." Both are legitimate. Nobody feeds their dog poorly because their budget doesn't allow for premium – but for snacks, the conscious choice is often worthwhile because they tie up a much smaller budget than the main meal.

And a final point: a snack is not complete nutrition. Even the purest meat snack does not replace a balanced main meal. Snacks are a side dish, not the main course. A maximum of 10% of the daily ration, the rest comes from the bowl.

Frequent Questions about the Prey Animal Principle for Snacks

Do I have to feed BARF to feed according to the Prey Animal Principle?

No. The principle also works if you give dry food or wet food as the main meal. You can simply apply it to your snack selection – that's the low-threshold option.

Is grain in snacks automatically bad?

No. A little rice or oats in a dog biscuit is not problematic. The Prey Animal Principle is violated when grain becomes the main ingredient and meat only serves as a flavor. Pay attention to the order in the ingredient list.

Which protein source is the "most natural"?

There is no ranking. Game, horse, poultry, lamb, beef, fish – anything can fit, depending on the dog. More important than the animal species is that it is a single source and the origin is transparent.

Are snacks with vegetables or fruit fundamentally wrong?

Not wrong, but not necessary. Some snacks have small amounts of vegetables or fruit – that doesn't make the snack worse, but also not better. The main question remains: what is the main ingredient?

How do I recognize if a snack is truly "prey animal-like"?

Three quick checks: Is an animal species with a percentage listed first in the ingredient list? Is the list overall short (under five lines)? Are sugar, artificial additives, and unclear generic terms absent? If yes to all three: it fits.

If you are looking for snacks that are based on the Prey Animal Principle – monoprotein, transparent origin, short ingredient list – you will find exclusively products that follow exactly this logic in the Dogvanture assortment. More about this can also be found on the Snackology page, where the principle is explained in detail.
