The BARF model diet is the most common and popular raw diet for dogs. A BARF diet can be home prepared with multiple ingredients to provide recommended allowances for essential nutrients.
BARF diet feeding ratios are slightly different from PMR diet ratios to include vegetables, seeds, and fruit.
BARF Model Ratio Guidelines
It is important to note the muscle meat ratio does not mean to feed muscle meat exclusively. This ratio is a large category containing multiple ingredients such as saturated fat for energy and muscular organs such as heart muscle meat.
Raw Edible Bone
Soft, raw edible bones are an important component to BARF diets to provide essential calcium, phosphorous, and other essential nutrients. The raw edible bone ratio guideline starts at 10% of the overall daily intake.
The amount of raw meaty bones a dog may need to maintain firm and consistent stool will vary. The 10% ratio is a starting guideline. However, many dogs do well on 12% to 15% raw edible bone content. Always adjust according to the dog’s individual needs.
The 5% liver ratio is a starting guideline and this amount of liver provides more than recommended allowances for vitamin A. For dogs who are sensitive to organs, feeding as low as 2% liver will still provide essential vitamin A.
Other secreting organs, such as kidney, are beneficial ingredients in BARF diets to provide essential minerals and water-soluble vitamins. The other organ ratio guideline starts at 5% of the overall daily intake.
Other secreting organs are beneficial in completing essential NRC nutritional requirements for dogs. The 5% ratio guideline is a starting recommendation, and more or less secreting organs can be fed to complete nutritional requirements.
Vegetables are beneficial in completing essential nutrient requirements for dogs. The 7% ratio guideline is a starting recommendation, and more or less vegetables can be fed to complete nutritional requirements.
Seeds & Nuts
Raw seeds and nuts are beneficial ingredients in BARF diets to provide essential minerals, fatty acids, and fat-soluble vitamins. The raw seed and nut ratio guideline starts at 2% of the overall daily intake.
Seeds and nuts are beneficial for completing essential nutrient requirements for dogs, but they must be pre-soaked and ground for feeding. Raw nuts and seeds contain phytates which are anti-nutrients that can negatively affect nutritional balance. Soaking raw seeds and nuts reduce phytates and grinding promotes optimal digestion. The 2% ratio guideline is a starting recommendation, and more or less can be fed to complete nutritional requirements.
Fruit includes beneficial ingredients in BARF diets to provide antioxidants, but they are fed in small amounts due to their sugar levels. The fruit ratio guideline starts at 1% of the overall daily intake.
If BARF ratio guidelines are fed without specific raw ingredients, the raw diet will be deficient in a few essential nutrients. The ratio guidelines for BARF are category terms and include a variety of ingredients that provide different nutrients essential to health.
Debunking Myths about Plant Ingredients
The inclusion of plant ingredients in raw diets for dogs can create a debate among many. There are many myths associated with feeding plant ingredients to dogs:
Dogs cannot digest plant ingredients.
Dogs can fully digest and absorb the nutrients from plant ingredients when they are prepared in a method to support optimal digestion. Puréeing raw, non-starchy vegetables is the easiest and most recommended method of preparation. Additionally, lightly steaming or fermenting vegetables are alternative preparation methods to promote optimal digestion.
If starchy vegetables are selected to feed, they must be thoroughly cooked before feeding. Boiling or baking starchy vegetables until fully cooked allows the starch to become digestible for dogs.
Vegetables and fruit are not needed for nutrients.
It is correct to say that vegetables and fruit are not needed for essential nutrients, but they do play a beneficial role in completing nutritional requirements in diets. Vegetables and fruit provide carbohydrates which can be used as a source of energy as well as fiber to support vitamin K synthesization and colon health.
Vegetables prove useful when completing nutrient requirements in PMR meals. Leafy greens are high in magnesium, which is a nutrient often deficient in PMR model meals.
Additionally, specific diets with ingredient restrictions rely on plant ingredients to complete nutritional gaps where needed. An example is low purine diets where organ meats are not fed. Therefore, the use of plant ingredients is warranted to create a complete and balanced diet.
Plant ingredients are not beneficial.
Vegetables and fruit contain carotenoids, flavonoids, antioxidants, and many other phytochemicals that are beneficial to immune function and health. These phytochemicals are not found in any other food sources other than plant ingredients.
To Feed or Not to Feed Plant Ingredients
Adding vegetables, seeds and nuts, and fruit to a dogs meal is not harmful in any way when dog-safe ingredients are selected. The dog can and will digest and absorb the nutrients from plant ingredients when they are prepared to support optimal digestion.
Selecting to add plant ingredients to a dog’s meal depends on individual requirements and how the dog tolerates plant ingredients. Always adjust to the dog’s individual needs.
