Dr. Marty Nature's Blend Freeze-Dried Raw Dog Food 48 oz (3 inch
✅ PROS
- Single-source protein formula (beef) that works well for dogs with poultry or grain sensitivities
- Freeze-drying preserves nutrients without high-heat processing; no fillers, artificial preservatives, or by-product meals
- Picky-eater track record is strong — multiple owners report dogs who refused kibble switching without a transition period
❌ CONS
- Premium price translates to roughly $4–6 per day for a 50-lb dog; budget shoppers will feel the hit
- Crumbly texture at the bottom of the bag — some powder residue is normal, not a defect
- Not a complete AAFCO meal for all life stages; puppies and gestating females need a different formula
The Verdict
If you’ve spent any time in dog nutrition circles, you’ve seen Dr. Marty’s Nature’s Blend pop up in social media ads and vet-adjacent forums. The 48-ounce bag commands premium pricing, but the real question is whether freeze-dried raw delivers on its promises — or just burns a hole in your wallet. I’ve dug through the ingredient panel, analyzed the feeding cost, and cross-referenced what 225 Amazon reviewers actually say. Here’s the unvarnished breakdown.
What’s actually in the bag
Nature’s Blend is a freeze-dried raw formula built around beef as the primary protein, with beef heart, liver, and kidney rounding out the organ content. The freeze-drying process removes moisture while preserving enzymes and nutrients that high-heat kibble manufacturing destroys. No corn, wheat, soy, or artificial preservatives — the ingredient list is short enough that you can read it in one breath.
The 48-ounce bag is the largest size available, and it’s worth noting the caloric density is high. One cup (about 4 ounces) delivers roughly 430 kcal, which means a 50-pound dog eats around 1.5 to 2 cups daily depending on activity level. That’s a real consideration when comparing against standard kibble — you’re paying for concentrated nutrition, not water weight.
Real-world performance and feeding experience
The texture is dense and crumbly — think a dry meatball that you break apart. Most owners rehydrate with warm water for 5-10 minutes before serving, which turns it into a soft, palatable mix. If you skip hydration, you’ll want to ensure your dog drinks plenty of water; the freeze-dried state is extremely low-moisture.
One thing I appreciate: this formula has a single protein source. That’s a meaningful advantage for dogs with known poultry sensitivities or grain allergies, which is a common reason owners migrate to raw in the first place.
What buyers consistently praise
The picky-eater conversion stories are the most consistent theme across verified reviews. One owner wrote, “My 11-year-old beagle has refused every kibble we’ve tried for two years. He cleaned his bowl the first night with Nature’s Blend.” Another noted, “I was skeptical of the price, but my dog’s coat is noticeably shinier after three weeks.”
Multiple reviewers with senior dogs reported improved energy levels and firmer stools within two weeks. That aligns with the nutrient profile — freeze-dried raw avoids the starch-heavy binders that kibble relies on, which often translates to better digestion.
Where it falls short
Let’s be direct about the downsides. First, cost. At roughly $4-6 per day for a medium-sized dog, this is a significant monthly expense — we’re talking $120-180 per month versus $40-60 for premium kibble. That’s the tradeoff for raw nutrition, and it’s not for every budget.
Second, the texture can be frustrating. The bottom of the bag inevitably collects fine powder from the freeze-dried chunks rubbing together during shipping. It’s not a defect — just rehydrate it along with the rest — but it’s a minor annoyance.
Third, and this matters for some households: this is not an AAFCO complete-and-balanced meal for all life stages. It’s formulated for adult maintenance. If you have a puppy under one year or a pregnant/nursing dog, you need a different product. Read the label before committing.
Who should buy this
- Owners of picky eaters who’ve exhausted kibble brands and need a proven appetite trigger
- Dogs with poultry or grain sensitivities — the single-protein beef formula eliminates common allergens
- Families already feeding raw who want a shelf-stable, travel-friendly option that doesn’t require freezer space
- Not for you if you’re on a tight pet-food budget or have a puppy under 12 months
FAQ
Q: How much do I feed per day? A: For a 50-lb dog, start at 1.5 cups daily in two meals. Adjust based on activity and body condition — the bag has a clear chart. Rehydrate with warm water for 5-10 minutes.
Q: Can I mix this with kibble? A: Yes, many owners use it as a topper to boost palatability. Just be aware that mixing reduces the overall nutritional profile to whatever the kibble provides — you lose some of the raw benefits.
Q: Does it need refrigeration? A: No, that’s the beauty of freeze-dried. Store in a cool, dry place and it’s shelf-stable for months. Once rehydrated, refrigerate leftovers and use within 24 hours.
The Verdict
Buy it if: Your dog is a chronic picky eater, has food sensitivities, or you’re ready to commit to premium nutrition and the budget that comes with it.
Skip it if: Your dog thrives on high-quality kibble, you have a puppy under a year, or the $150+ monthly cost is a stretch.
Rating: 4.6/5 — The price is the only real deterrent. For nutrition density, ingredient quality, and picky-eater success, this delivers exactly what it promises.
