There are multiple diet types for raw feeding – Prey Model Raw (PMR), Biologically Appropriate Raw Foods (BARF), and Ketogenic Raw Foods (Keto). Each diet type is unique in its own way, but they are all created with specific raw ingredients.
There are several factors to take into consideration when choosing a feeding model for a dog or cat. Identifying if PMR or BARF depends on the pet’s individual needs.
A raw diet following PMR guidelines includes 80% muscle meat, 10% raw edible bone, 5% liver, and 5% other secreting organs. Diet guidelines can be achieved through whole prey and Frankenprey feeding methods.
Whole prey is a whole, intact, prey animal with fur or feathers and the includes all internal organs, bones, blood, and glands. Frankenprey is the assembly of different animal sources to complete the PMR feeding guidelines.
A raw diet following BARF guidelines includes 70% muscle meat, 10% raw edible bone, 5% liver, 5% other secreting organ, and 10% plant ingredients. Diet guidelines can be achieved by using different animal sources and produce to complete the BARF feeding guidelines.
A Keto raw diet is a therapeutic diet intended to be fed to dogs and cats with cancer. A raw Keto diet requires a 2 to 1 ratio of fat to protein. The 2:1 ratio refers to a diet with twice the amount of calories from fat in comparison to protein and net carbohydrates combined. This diet plays a supportive role in fighting against cancer; but is not intended to be fed long term.
A hybrid raw diet encompasses both PMR and BARF feeding guidelines which is based on the premise that balance can be achieved over time. One meal can follow PMR guidelines and the next meal follows BARF guidelines to complete the recommended allowances for essential nutrients.
Balance over time is not recommended when feeding puppies due to their inability to store and regulate nutrients like an adult dog. Puppies require daily nutritional balance to support healthy growth and development.
Canines are facultative carnivores where their nutrient requirements are fulfilled by animal based foods. However, dogs can absorb and utilize nutrients from plant based foods when prepared to allow for optimal digestion.
Both PMR and BARF model diets are suitable for dogs. However, a PMR diet can be lacking in specific essential nutrients that are easily provided through vegetables, seeds, and fruit found within a BARF diet. Deficient nutrients in PMR style diets can be fulfilled with supplements, but it is recommended to utilize whole foods to include these nutrients. If whole prey is not frequently fed, a BARF model diet or a hybrid raw diet is recommended.
Felines are obligate carnivores where their nutrient requirements must be fulfilled by animal based foods. PMR model diets by feeding Franken Prey and Whole Prey are suitable for cats.
