Is bison really a novel protein for dogs?

Yes, for most US dogs. The vast majority of commercial pet food uses chicken, beef, turkey, lamb, fish, or pork as the primary protein source. Dogs that have never eaten bison have no prior immunologic exposure to bison-specific proteins, so bison is a useful elimination-diet protein for dogs with suspected food allergies or food sensitivities. Bison is also leaner than commercial beef (typically 2-3% fat in lean cuts), grass-fed by default in the US bison industry, and free from hormone implants used in some conventional cattle production. For elimination-diet protocols, novel proteins like bison, venison, rabbit, or kangaroo are the structurally aligned picks; beef-based diets like Answers Detailed Beef are not.

Raw Bistro vs Answers Pet Food: Which Is Better for Your Dog?

Q: Is Raw Bistro or Answers Pet Food better for dogs?

Effectively tied at A/90 vs A/90 on the v15 rubric. Raw Bistro leads with grass-fed Minnesota bison (novel protein for elimination diets) and eight USDA-certified-organic produce ingredients. Answers Pet Food leads with grass-fed beef and adds a uniquely deep raw-fermented-dairy layer (whey + butter + kefir with four named Lactobacillus strains). Pick on protein preference (bison vs beef) and probiotic priority (Raw Bistro’s clean panel vs Answers’ deep natural probiotic load).

Q: Does Raw Bistro have probiotics like Answers?

Not directly. Raw Bistro includes inulin (extract of chicory root) at #12 as a prebiotic fiber that supports hindgut bacterial fermentation, but it doesn’t include direct probiotic bacteria. Answers Pet Food includes whey + butter + kefir with four named Lactobacillus strains (L. bulgaricus, L. acidophilus, Leuconostoc mesenteroides, L. lactis) at densities synthetic probiotic supplementation can’t match. For owners specifically prioritizing deep natural probiotic load, Answers is the structurally aligned pick. For dogs with confirmed dairy allergy, Raw Bistro is the dairy-free alternative.

The short answer: Effectively tied at A/90 vs A/90 on the v15 rubric. Both are A-tier frozen-raw whole-prey-model recipes from independent (non-conglomerate) US brands. Raw Bistro leads with grass-fed Minnesota-family-farm bison and eight USDA-certified-organic produce ingredients including organic walnut oil. Answers Pet Food leads with grass-fed beef and adds a uniquely deep raw-fermented-dairy layer (whey + butter + kefir with four named Lactobacillus strains) that no other US commercial raw brand carries at this depth. Pick on protein preference (bison novel-protein vs beef) and probiotic priority (Raw Bistro’s clean panel vs Answers’ deep natural probiotic load).

The scores

Raw Bistro Frozen Bison Entree: A (90/100) — Bison, Bison Heart, Bison Kidney, Ground Bison Bone, Bison Liver.

Answers Pet Food Detailed Beef Formula: A (90/100) — Beef, Beef Heart, Beef Liver, Beef Kidney, Ground Beef Bone.

How the ingredients compare

The top-five ingredients reveal the formulation split between these two products:

Raw Bistro: Bison, Bison Heart, Bison Kidney, Ground Bison Bone, Bison Liver

Answers: Beef, Beef Heart, Beef Liver, Beef Kidney, Ground Beef Bone

Both products earn effectively the same v15 score, but the ingredient lineups tell different stories about how they got there — that is where the actual pick decision lives.

Where Raw Bistro pulls ahead

Novel-protein bison for elimination-diet utility: Raw Bistro leads with bison — a novel protein for most US dogs with no prior immunologic exposure. For dogs with suspected beef or chicken protein sensitivities, bison is a useful elimination-diet protein. Answers’ Detailed Beef Formula uses beef — common in the food-allergy trigger top six (beef, chicken, dairy, wheat, lamb, soy). Owners running elimination-diet protocols often need to avoid beef specifically; Raw Bistro’s bison is structurally aligned. Shop on Amazon →

Eight USDA-certified-organic produce ingredients + organic walnut oil: Raw Bistro runs every plant ingredient as USDA-certified-organic (butternut squash, broccoli, red peppers, blueberries, walnut oil, kelp, plus inulin from chicory). Few raw brands run their entire produce section as certified organic. Organic walnut oil for omega-3 ALA is also unusual — most peer brands use flaxseed or fish oil. Answers uses organic produce (carrots, green squash, eggs, broccoli) but not the full panel.

Minnesota family-farm independent ownership transparency: Raw Bistro is produced by a Minnesota family-farm operation that opened its first commercial small-batch raw-pet-food facility in 2009. Bison is sourced from US grass-fed ranches; produce is certified-organic from regional suppliers. The family-farm sourcing transparency and the single Minnesota facility model give owners tighter supply-chain visibility than larger multi-state operations.

Where Answers holds its own

Raw-fermented dairy layer with four named Lactobacillus strains: Answers includes whey, butter, and kefir with four explicitly-named strains (L. bulgaricus, L. acidophilus, Leuconostoc mesenteroides, L. lactis). No other US commercial raw brand carries this fermentation depth. Raw kefir routinely supplies 10-100 billion CFU per cup — densities synthetic probiotic supplementation (typically 10-100 million CFU per scoop) can’t match. For dogs with chronic GI sensitivity, post-antibiotic dysbiosis, or microbiome-axis skin issues, the structural probiotic load is the brand’s differentiator. Raw Bistro doesn’t include fermented components. Shop on Amazon →

Cod liver in primary position for marine omega-3: Answers includes cod liver at #9 — the whole-food form (not isolated cod liver oil), which delivers marine EPA + DHA omega-3 plus natural vitamin D in matrix form. The marine omega-3 contribution is more bioavailable for dogs than the plant ALA in Raw Bistro’s walnut oil (the ALA-to-EPA conversion in dogs runs only 5-10%). For dogs needing high direct marine omega-3 for joint, skin, or inflammatory support, Answers’ cod liver inclusion is structurally meaningful.

Beef as conventional palatability default: Answers uses beef — the most-commonly-accepted protein for picky-eater dogs and the easiest protein for transitioning dogs from beef-based kibble. Beef is also widely available, with no novel-protein supply-chain risk (some novel proteins like bison can have supply-chain disruption during ranching off-seasons). For owners specifically wanting a beef-based raw recipe with fermented-food differentiation, Answers’ Detailed Beef Formula is the structural pick. Raw Bistro’s bison is more elimination-diet specialized.

The bottom line

Effectively tied at A/90 vs A/90 — the pick comes down to protein and probiotic priority, not score gap. Pick Raw Bistro for novel-protein elimination-diet utility (bison), USDA-certified-organic produce sourcing across the whole panel, and Minnesota family-farm independent ownership transparency. Pick Answers Pet Food for the uniquely deep raw-fermented-dairy layer (whey + butter + kefir with four named Lactobacillus strains), beef as the conventional palatability default, and cod liver for direct marine omega-3. Both are frozen-raw whole-prey-model recipes requiring freezer space + thaw protocols + careful raw-meat handling.
