Rawboost Whole Grain Gut Health Chicken & Brown Rice Dry Dog Food
Verified May 26, 2026
This is a high-protein, whole-grain dry dog food that combines chicken-based kibble with freeze-dried raw chicken pieces, designed for dogs needing support for everyday digestion. It uses brown rice, barley, and oatmeal as the main carbohydrates, with added prebiotics, multiple probiotic strains, and fiber sources like beet pulp and chicory root to help maintain a healthy gut. Omega fatty acids, joint-support nutrients, and antioxidant-rich fruits and vegetables round out the formula for all life stages, except large-breed puppies.
Nutritionally, this is a high-quality, protein-rich kibble with added freeze-dried raw pieces and a strong focus on digestive support. It offers good levels of animal protein from multiple chicken sources and fish meal, along with whole grains and targeted gut-health ingredients like prebiotics and several probiotic strains. It suits most puppies and adult dogs well, but it is not appropriate for large-breed puppies and may not be ideal for dogs with chicken or egg allergies.

Strengths
- 30% protein and 15.5% fat from named animal sources (chicken, chicken meal, fish meal, freeze-dried chicken and organs) provide strong overall amino acid and energy support.
- Includes whole grains such as brown rice, barley, and oatmeal, plus diverse fiber sources (beet pulp, chicory root, citrus pulp) that can support regular stools and gut health.
- Added probiotics (multiple strains totaling at least 80 million CFU per pound), prebiotic fibers, and omega-3 and omega-6 fatty acids for digestive and skin/coat support.
- Contains glucosamine and chondroitin sulfate, which can help support joint health, and is AAFCO-formulated for all life stages except large-breed growth.
Considerations
- Not suitable for large-breed puppies (expected adult weight 70 lb or more) based on the AAFCO statement; those dogs should be on a diet specifically formulated for large-breed growth.
- Chicken, chicken meal, chicken liver/heart, egg, and fish are key ingredients, so this food will not work for dogs with allergies or intolerances to these common proteins.
- At 428 kcal per cup, this is a relatively calorie-dense food, so portion control is important, especially for less active or small dogs to help avoid weight gain.

Top 5 Ingredients Explained
01
Chicken
Chicken is a common animal-based protein in dog and cat foods, supplying essential amino acids, B vitamins, and energy-dense fats that support muscle maintenance, growth, and overall health; for cats it also contributes toward dietary taurine but must be present in sufficient amounts or provided via supplementation. It is prized for its digestibility and palatability, though some pets develop sensitivities or allergies to chicken, and nutritional value and safety depend on ingredient quality and processing—raw chicken carries pathogen risks and whole bones can pose choking or GI hazards.

03
Brown Rice
Brown rice is a whole-grain carbohydrate and fiber ingredient commonly used in dog and cat foods to provide digestible energy, dietary fiber, and modest amounts of B‑vitamins and minerals; it typically offers more nutrients and fiber than white rice. It’s generally well tolerated and can help with sensitive stomachs, but because it is high in carbohydrates (not a primary protein source) and can contain trace inorganic arsenic depending on sourcing, it should be included in balanced formulations and monitored in overweight or diabetic pets.
04
Barley
Barley is a cereal grain used in pet foods primarily as a digestible carbohydrate and source of dietary fiber (including soluble beta‑glucans), along with modest amounts of B vitamins and minerals. It can support healthy digestion, help moderate post‑meal blood sugar and aid weight management in dogs, but provides limited protein for obligate carnivores like cats, must be cooked/processed for good digestibility, and may be unsuitable for pets with grain sensitivities or calorie‑restricted diets.
05
Fish
Fish is commonly used in pet foods as a highly digestible animal protein and an excellent source of omega‑3 fatty acids (EPA and DHA) that support skin and coat health, joint function, and cognitive development in both dogs and cats. It also supplies B vitamins and minerals but can be a common allergen, may contain environmental contaminants or mercury depending on species and sourcing, and raw fish can contain thiaminase—so choose properly processed, nutritionally balanced, and sustainably sourced fish ingredients.
