Prey Model Raw (PMR)

Welcome to’s raw feeding section where you will find everything you need to know to start your four-legged friend on a species appropriate diet, there are two main models of raw feeding that are listed below.

  • Prey Model Raw (PMR) or Whole Prey Model,

  • BARF Model (Biologically Appropriate Raw Feeding or Bones and Raw food).

On this page, we are going to focus on the Prey Model Raw (PMR) approach to raw feeding so let’s jump straight in and learn how to start your pet on a Prey Model Raw (PMR) diet!

Prey Model Raw (PMR)


The ethos of this model is to attempt to resemble what our pet’s ancestors would eat in the wild which we know is whole prey. Prey Model Raw, if you haven’t guessed already this is when you feed your pet the whole animal.

An example of this is feeding a whole rabbit or squirrel.

This is the perfect model since we as raw feeders are ultimately trying to mimic what our dog’s ancestors the Grey Wolf would eat in the wild. A Prey Model Raw feeder believes that dogs are true carnivores and have strict rules on what they think is appropriate for their pet to eat.

The PMR model excludes:

  • Vegetables

  • Fruits

  • All Dairy

  • And Limits Supplementation,

This model is the strictest out of the two and a true PMR feeder thinks that their pet does not need to eat any of the above and their diet should solely consist of whole prey.

However, some PMR feeders do supplement with Omega 3 fatty acids, as standard commercial proteins such as intensely reared chickens have been fed a diet of high grains which results in much lower Omega-3 fatty acids being present than a high welfare bird or wild prey. Even though this model focuses on feeding whole prey there are two different approaches a PMR feeder can take when using this model.

Your options for feeding whole prey to your pet are

  • Feeding strictly just whole prey,

  • Or Franken Prey feeding.

Know we know what feeding strictly whole prey is but what is Franken Prey feeding?

Well, this is when PMR feeders piece together different proteins to reach the required ratios of whole prey. This is an easier way of feeding the PMR method as not everyone can get their hands on whole prey with feathers and innards still intact. An example of this is a PMR feeder giving their pet a whole duck or chicken from the supermarket and giving them offal and maybe some rabbit pelt on the side to mimic feeding whole prey.

My Staffordshire Bull Terrier, Nia loves eating whole prey, her favourite being a squirrel or whole rabbit. However, my Border Terrier Lily is far too fussy to even humour the idea of eating whole prey!! I think this model is great if you can get a constant supply of whole prey and even Franken Prey feeding is a more convenient way of feeding your pet using the Prey Model Raw (PMR) method.

If you want to follow the Prey Model Raw (PMR) method, then you will feed your pet:

  • 80% Muscle Meat

  • 10% Raw Meaty Bones

  • 10% Organs & Offal (5% of this must consist of liver!)

This is what a PMR feeder would give their pet following this method. To work out how much your pet should be eating each day simply head over to our Raw Feeding Percentages page.

The Pros of the Prey Model Raw/Whole prey method?

There are many pros to feeding a Prey Model Raw diet and below I’m going to list a small handful of the many benefits your pet can benefit from when consuming a raw food diet.

  • It’s the most simple and effective method out of the two for ensuring your pet is getting everything they require on a raw diet.

I would say this is the main selling point for me, the fact that all you have to do is find the correct weighing whole prey then stick it down for your furry friend to enjoy. There is no worrying about giving your pet the correct ratios because everything is already perfectly balanced.

  • It’s quick & easy which saves time.

One of my favourite things about feeding a Prey Model Raw diet is the how simple it is, all you have to do is make sure you are feeding the correct weighing whole prey and you’re sorted. Whereas when feeding the BARF method it is a lot more time-consuming if you choose to make your pet’s meals following the DIY BARF approach.

  • Identical to your pet’s natural diet.


Your pet is a domesticated wolf and shares a whopping 98.8% of its genetic makeup with a Grey Wolf, therefore the only real difference between the two is their temperament and appearance, their digestive systems are the same. By feeding your dog using this method you are providing them with a diet they are built to eat and that is similar to their closest ancestors, the Grey wolf.

So that’s the pros, now let’s talk about what could be considered not so great about the Prey Model Raw method.

The Cons of a Prey Model Raw Diet

There are a few drawbacks when it comes to feeding a Prey Model Raw diet but these can be easily solved and shouldn’t putting you off this raw feeding model.

  • It can be a bit messy.

The main issue with feeding a Prey Model Raw diet is that is can be a bit messy when feeding inside your home. Since your feeding, a whole animal that still has all its guts and unfortunately poo inside this can result in some of those innards going all over your kitchen floor. However, this can be solved easily by feeding outside in your garden or by purchasing an extra-large feeding mat.

  • It isn’t a good method for fussy pets.


I have both extremes with my girls, Nia is pretty much willing to eat anything and turns her nose up at very little. Whereas Lily the youngest out of the two is about as fussy as it gets and won’t consider eating whole prey. If we are lucky she will occasionally eat some rabbit pelt or a chick if she’s feeling adventures but that’s as far as she will go!

So this method of raw feeding for fussy pets is not the best.

  • It can be hard to get hold of enough whole prey to solely just feed your pet using this method.

Unless you’re a farmer or hunter it can be difficult to get hold of enough whole prey to feed your pet for the month. We order our raw food from Scruffles Pet Supplies, Durham Animal Feeds or Paleo Ridge and some months there isn’t a lot of whole prey on offer which limits how much we can feed. Therefore this is quite a drawback when it comes to feeding a Prey Model Raw diet.

I hope you all liked learning about the Prey Model Raw (PMR) method of raw feeding and if you do decide to start your pet on a raw diet do let us know. Prey Model Raw is a great raw feeding method and I would say my girl Nia eats a lot more whole prey than minces or chunks. Whereas Lily wouldn’t even humour the idea of eating whole prey so it certainly isn’t for everyone.

However, I think we can all agree that feeding our companion animals a diet that is suited to their genetic makeup is the best approach for keeping them strong and healthy and having them by our side for as long as possible. To learn about the other model of raw feeding, BARF (Biologically Appropriate Raw Food Or Bones and Raw Food) then simply head over to our Biologically Appropriate Raw Feeding page.
