Top 10 Freeze Dried Liver Dog Treats
Detailed Product Reviews
1. Nutri Bites Freeze Dried Beef Liver Dog & Cat Treats | Healthy Pet Training Treats or Food Topper | All Natural, Single Ingredient, High Protein | Premium Bulk Value Pack, 17.6 oz
Overview: Nutri Bites delivers a wallet-friendly 17.6 oz pouch of pure beef-liver crunch that works for both dogs and cats. The pieces are uniform, low-crumb, and sized for quick training rewards or meal toppers.
What Makes It Stand Out: The brand’s “less dust” freeze-dry method really does leave almost no powder in the bag—handy if you toss a handful in your pocket. The resealable pouch keeps the liver aromatic for months without refrigeration.
Value for Money: At ≈$1.19/oz you get almost 18 oz of USA-sourced liver; that’s roughly 30% cheaper per ounce than big-name tubs, making it the sweet spot for multi-pet homes.
Strengths and Weaknesses:
Pros: single ingredient, high protein, pets universally love the taste, large quantity lasts 8-10 weeks for a 50-lb dog.
Cons: occasional inconsistency in piece size (some chunks need breaking), bag is bulky for small kitchens, not made in USA (sourced from South America).
Bottom Line: If you want maximum ounces per dollar and aren’t picky about country of origin, Nutri Bites is the best bulk buy for everyday rewarding.
2. Stewart Single Ingredient Freeze Dried Raw Dog Treats, Beef Liver, 21 Ounce Value Size, Approx. 475 Pieces per Resealable Tub, Training Treats or Meal Topper, High Protein, Grain Free, Gluten Free
Overview: Stewart has been freeze-drying liver in Dayton, Ohio since 1973 and packages 21 oz (≈475 treats) in a screw-top tub that sits neatly on a shelf.
What Makes It Stand Out: CNN Underscored’s 2024 “top treat” pick; trainers like the tub because it opens one-handed and the liver aroma stays locked in. USDA-certified U.S. beef only.
Value for Money: $1.71/oz is higher than competitors, but you’re paying for domestic sourcing, small-batch production, and a reusable tub—still under 8¢ per treat.
Strengths and Weaknesses:
Pros: uniform dice-sized cubes, virtually no crumbs, made & sourced in USA, long 3-month supply, cats love them too.
Cons: premium price, tub lid can crack if dropped, slight greasy film on inside wall in hot weather.
Bottom Line: For owners who value American craftsmanship and a tidy container, Stewart is the professional’s choice—worth the extra cents per day.
3. Nutri Bites Freeze Dried Beef Liver Dog & Cat Treats | Healthy Pet Training Treats or Food Topper | All Natural, Single Ingredient, High Protein | Premium Bulk Large Size Pack (27 OZ)
Overview: Nutri Bites ups the ante with a 27 oz “XL” bag—same single-ingredient beef liver as their 17.6 oz version, just more of it.
What Makes It Stand Out: Largest single-pouch option on Amazon at under $0.91/oz; still claims low-dust processing and added zinc & vitamin A for immune support.
Value for Money: Cheapest per ounce in the entire lineup; one bag lasts a 70-lb dog the better part of four months.
Strengths and Weaknesses:
Pros: unbeatable price-to-weight ratio, resealable zipper, high palatability for picky eaters.
Cons: foreign sourcing (South America), bag is awkwardly tall for some cabinets, vitamin claims aren’t third-party verified, occasional overly hard shards.
Bottom Line: If your mantra is “volume over pedigree,” the 27 oz XL bag is the budget king—just inspect each piece for hardness before handing it to small dogs.
4. Vital Essentials Beef Liver Dog Treats, 2.1 oz | Freeze-Dried Raw | Single Ingredient | Premium Quality High Protein Training Treats | Grain Free, Gluten Free, Filler Free
Overview: Vital Essentials packages 2.1 oz of “butcher-cut” Midwest beef liver in a bright pouch aimed at raw-feeding purists who want artisanal quality.
What Makes It Stand Out: Protein frozen within 45 minutes of harvest, then slow freeze-dried; company offers the widest single-protein catalog for rotation feeding.
Value for Money: $2.85/oz makes this the priciest per ounce—think of it as the craft-beer equivalent of liver treats.
Strengths and Weaknesses:
Pros: ultra-fresh aroma, paper-thin light pieces perfect for tiny puppies or cats, USA sourced & processed, no fillers whatsoever.
Cons: wallet shock, only ~40-45 treats per bag, zipper sometimes fails after opening, crumbs settle at bottom.
Bottom Line: Ideal for sampler trials, travel, or ultra-picky pets; buy it for quality, not quantity, and keep a cheaper tub for daily use.
5. Caledon Farms Freeze Dried Beef Liver Bites Dog Treats, 150 Grams/5.3OZ
Overview: Canadian company Caledon Farms freeze-dries 150 g (5.3 oz) of beef liver into airy, thumbnail-sized bites sold at big-box stores and boutique pet shops alike.
What Makes It Stand Out: Light texture breaks instantly in a dog’s mouth, reducing choking risk for brachycephalic breeds; resealable stand-up pouch has a clear window so you can see leftover volume.
Value for Money: Mid-range at $1.51/oz; you pay for Canadian food-safety standards without the import premium of some U.S. brands.
Strengths and Weaknesses:
Pros: single ingredient, low odor, easy snap for training “jackpots,” iron & zinc content clearly labeled.
Cons: only 5 oz means heavy trainers will burn through it in a week, some bags arrive half powder, not quite as aromatic as U.S. competitors.
Bottom Line: A solid middle-weight option for owners who want ethical sourcing and gentle texture without committing to a 20 oz tub.
6. Tomo Wellness NutriBites Freeze Dried Liver Treats for Dogs & Cats – High-Protein Single Ingredient Freeze Dried Dog Treats, Beef Liver – Proudly Made in Canada – 27 OZ HIGH PROTIEN Natural Grain
Overview: Tomo Wellness NutriBites deliver a massive 27-ounce tub of Canadian-sourced, freeze-dried beef liver that works for both dogs and cats. The bulk format is designed for multi-pet households or trainers who rip through treats fast.
What Makes It Stand Out: You get nearly 2.5× the weight of most competitors for under $23, dropping the per-pound price to $13.62—one of the lowest in the single-ingredient category—while still keeping the recipe 100 % beef liver with zero fillers.
Value for Money: At roughly 50 cents an ounce, this is the budget king of freeze-dried liver. The resealable plastic tub reduces crumble waste, and the uniform cube size makes portion control easy, so the bag lasts longer than cheaper, dust-heavy alternatives.
Strengths and Weaknesses: Strengths include unbeatable price per pound, neutral aroma compared with greasy trays, and a texture that breaks cleanly for tiny mouths. Weaknesses: cubes can vary in dryness, occasional powder at the bottom of the tub, and the large size means you’ll need freezer space if you want to keep it ultra-fresh after opening.
Bottom Line: If you burn through high-value rewards daily, NutriBites is the smartest wallet-friendly choice without sacrificing protein purity or palatability.
7. PureBites Beef Freeze Dried Dog Treats, 1 Ingredient, Made in USA, 11oz
Overview: PureBites Beef Liver treats cram 2.2 lb of raw USA beef liver into an 11-oz bag, yielding about 270 paper-than shards that melt quickly in a dog’s mouth. The brand targets health-conscious owners who want human-grade, single-ingredient rewards.
What Makes It Stand Out: PureBites uses a “delicate” freeze-dry cycle that leaves each piece RAW yet shelf-stable, locking in 5-calorie micro-treats ideal for repetitive training. The recyclable bag and 100 % money-back guarantee add eco and purchasing confidence.
Value for Money: At $40.71/lb you’re paying premium, but you’re also buying 2.2 lb of fresh liver that would cost ~$10 raw and spoil in days; the convenience, portion count, and diabetic-friendly profile justify the tariff for many.
Strengths and Weaknesses: Pros: ultra-light, easy to hide in pockets, virtually no smell, and dogs go bonkers for them. Cons: high price per pound, lots of dusty crumbs at the bottom, and fragile pieces that turn into powder if sat on.
Bottom Line: For precision training, allergy management, or dogs on restricted diets, PureBites is worth the splurge—just store the bag upright to save every last flake.
8. Stella & Chewy’s Freeze-Dried Raw Beef Liver Dog Treats – Single Ingredient, No Additives – Premium Training Treats – Perfect For Picky Eaters – 3oz Bag
Overview: Stella & Chewy’s Freeze-Dried Raw Beef Liver comes in a petite 3-oz pouch positioned as a premium, USA-made topper or high-value training reward for picky eaters. The company leans on its raw nutrition heritage to promise superior palatability.
What Makes It Stand Out: The morsels are diced into uniform “pill-size” cubes that don’t leave greasy residue on your hands; the brand also advertises naturally occurring iron, copper, and B-vitamins to support liver function and coat shine.
Value for Money: At $79.95/lb this is the most expensive option on the list—over $5 per ounce—so you’re buying boutique branding and consistent cube sizing more than sheer quantity.
Strengths and Weaknesses: Strengths include dogs’ frantic enthusiasm, resealable pouch that actually works, and virtually no dust. Weaknesses: wallet-busting cost, small bag runs out fast during heavy training, and cubes can be hard for toy breeds to chew.
Bottom Line: Perfect for spoiling a picky eater or jazzing up boring kibble, but budget-minded shoppers should reserve it for special occasions rather than daily reinforcement.
9. McLovin’s Pet Freeze Dried Raw Beef Liver Dog Treats and Toppers, 14 oz. – Single Ingredient, Grain-Free, Gluten-Free, High-Protein Treat – Healthy Dog Training Treats
Overview: McLovin’s Pet offers 14 oz of single-ingredient beef liver in a mid-sized, resealable stand-up pouch marketed as both treat and meal topper. The brand name may raise eyebrows, but the recipe is dead-serious: just liver, freeze-dried in the USA.
What Makes It Stand Out: The pieces are sliced thinner than most, creating crisp “chips” that break without crumbling excessively—great for owners who like to customize treat size on the fly. Grain/gluten-free credentials cater to sensitive stomachs.
Value for Money: $22.49 for 14 oz lands at $25.70/lb—middle of the pack—while still undercutting premium labels like Stella & Chewy’s by 65 %.
Strengths and Weaknesses: Pros: light texture dogs inhale, minimal odor, generous fill level, and zip-top that stays closed. Cons: chips can shatter into shards during shipping, lighter color suggests slightly longer freeze-dry time (less nutrition retention), and name branding feels gimmicky.
Bottom Line: A solid, fairly priced workhorse treat that balances quality and quantity; ideal for multi-dog homes that need high-value rewards without the sticker shock of boutique brands.
10. Amazon Brand – Wag Freeze-Dried Raw Single Ingredient Dog Treats, Lamb Liver, High Protein, Healthy Training Treats or Meal Topper for all Dogs, Grain-Free, 3.3oz
Overview: Amazon’s Wag Lamb Liver treats swap the usual beef for New Zealand/Australian lamb liver, freeze-dried in the USA and sold in a 3.3-oz pouch. The house-brand pricing aims to undercut name competitors while maintaining single-ingredient purity.
What Makes It Stand Out: Lamb offers a novel protein for dogs allergic to beef or chicken, and the $9 price point translates to $43.64/lb—cheaper than PureBites or Stella & Chewy’s but pricier than Tomo or McLovin’s beef options.
Value for Money: You’re paying for novelty protein and Amazon’s no-questions return policy. The 3.3-oz size is trial-friendly, yet cost per pound climbs if you move to larger bags (currently unavailable).
Strengths and Weaknesses: Strengths: strong lamb aroma drives motivation, pieces are soft enough to tear, resealable pouch keeps freshness, and sourcing transparency is solid. Weaknesses: limited size range, lamb smell can be polarizing for humans, and some inconsistency in piece thickness.
Bottom Line: A smart, affordable intro to novel-protein training treats—great for allergy testing or adding variety—though heavy users will want a bigger bag option soon.
What Makes Freeze-Dried Liver a High-Value Reward?
High-value is trainer-speak for “will-work-for-anything-else-is-boring.” Freeze-dried liver checks the box because it delivers three critical reinforcers: scent intensity, rapid dissolve, and rare-ingredient novelty. The low water activity concentrates odor molecules, making the cloud of aroma that escapes the pouch a built-in attention magnet. Meanwhile, the porous structure breaks down in seconds, allowing lightning-fast delivery and lightning-fast swallowing—perfect for shaping precise behaviors.
Understanding the Freeze-Drying Process
Freeze-drying (lyophilization) is not dehydration’s cousin; it’s the VIP lounge of preservation. Raw liver is flash-frozen to –40 °C, then placed in a vacuum chamber where ice sublimates directly into vapor, skipping the liquid phase. The result: cellular architecture stays intact, amino acids remain unoxidized, and pathogens are arrested without the nutrient-leaching side effects of high heat.
Nutrient Retention vs. Other Preservation Methods
Oven dehydration can denature heat-sensitive B-vitamins by 30–60 %, while air-drying exposes fats to rancidity. Freeze-drying preserves 97 % of vitamin A and virtually all selenium, heme iron, and taurine—nutrients that turbo-charge retinal health, oxygen transport, and cardiac function.
Texture and Palatability Drivers
Sublimation leaves micro-tunnels inside each cube, creating a honeycomb that fractures under the slightest jaw pressure. That crunch-then-creamy mouthfeel triggers both mechanoreceptors and fat-taste receptors, explaining why even picky eaters pause mid-zoomie to comply.
Species Spotlight: Beef, Lamb, Pork, Chicken, Turkey, and Exotic Options
Each species carries a unique flavor signature and micronutrient fingerprint. Beef liver is richest in copper and vitamin B-12, while lamb offers a slightly gamey aroma favored by herding breeds. Pork is naturally sweeter, chicken is hypoallergenic for many, and turkey sits lowest on the calorie-per-gram scale. Bison, venison, alpaca, and kangaroo appeal to elimination-diet dogs and sustainability-minded handlers.
Functional Benefits for Training, Sports, and Enrichment
Liver treats are calorie-dense, so a sesame-seed–sized piece can mark a perfect heel pivot without filling a dog before dinner. The rapid absorption of heme iron supports oxygen kinetics—handy for agility dogs sprinting 20-second courses. Crumbled dust at the bottom of the bag doubles as scent-work sprinkle, turning cardboard boxes into a brain-draining puzzle.
Key Nutrients: Iron, B-Vitamins, Vitamin A, and Taurine
One gram of freeze-dried beef liver provides roughly 200 % of a 20 lb dog’s daily vitamin A requirement—crucial for night vision in dock-diving competitions under stadium lights. The complete B-complex acts as enzymatic co-factors for energy metabolism, keeping detection dogs mentally crisp during 4-hour searches. Taurine, abundant in lamb and poultry liver, underpins cardiac contractility inlarge-breed athletes.
Sourcing Transparency: Pasture-Raised, Grass-Fed, and Regenerative Farming
Regenerative farms rotate livestock on diverse forage, increasing soil carbon capture and yielding liver with a healthier omega-3:6 ratio—translating to silkier coats and less systemic inflammation. Look for on-farm slaughter and single-day freeze-dry schedules; every extra hour at ambient temperature oxidizes lipids and drops palatability.
Quality Red Flags: Fillers, Additives, and Misleading Labels
“Liver flavor” or “liver product” can signal spray-dried digest rather than pure organ. Silicon dioxide prevents clumping but strips moisture from canine oral mucosa. Avoid treats preserved with BHA, BHT, or ethoxyquin—the same synthetic antioxidants banned in human food in 160 countries.
Portion Control and Calorie Density
Freeze-dried liver packs 4–5 kcal per gram; a piece the size of a postage stamp equals a teaspoon of commercial kibble. Use the 10 % rule: treats should stay under one-tenth of daily caloric intake to avoid diluting complete-and-balanced meals. Investing in a jeweler’s scale lets you portion to the 0.1 g, ensuring precise drive without waistline creep.
Allergies and Novel Protein Strategies
Liver is glandular tissue, so it shares allergenic epitopes with muscle meat. If your dog reacts to chicken breast, chicken liver is likely off-limits. Rotate among three novel species every 4–6 weeks to minimize antibody development, and keep an eye on ear-pinna redness or post-treat foot-chewing as early warning signs.
Safety Concerns: Pathogen Control, Storage, and Handling
Although freeze-drying knocks down Salmonella and E. coli by 5–6 logs, it does not sterilize. Opt for brands that conduct post-dry HPP (high-pressure processing) or test each lot for Enterobacteriaceae. Once opened, transfer treats to a food-grade desiccant jar; oxygen absorbers prevent lipid oxidation and extend shelf life to 18 months post-pack date.
Sustainable Packaging and Carbon Pawprint
Aluminum-lined kraft pouches are recyclable through store drop-off programs, whereas multi-layer plastic films are legacy waste. Some 2025 suppliers pilot compostable cellulose bags with plant-based valves—look for the “OK Home Compost” seal to ensure backyard breakdown within 26 weeks.
Price Per Training Rep: Budgeting for Serious Trainers
A 200-treat-per-week agility program can burn 400 g monthly. Calculate cost per gram, then divide by average reps per gram (roughly 40 for pea-sized pieces). Premium pasture-raised beef liver may land at $0.025 per rep—half the price of string cheese and three times the motivation.
DIY Freeze-Drying at Home: Feasibility, Costs, and Food Safety
Home freeze-dryers start at $2,500 and require a 20-amp circuit plus vacuum pump maintenance. You’ll need to pre-freeze liver slabs for 48 hours, then run 24-hour cycles. Factor in electricity (≈$3.50 per batch) and periodic pump oil changes. Unless you process 100 lb of meat yearly, the ROI still favors boutique suppliers with batch-testing protocols.
Transitioning From Commercial Treats to Pure Liver
Sudden jumps to rich organ meat can trigger loose stools. Swap 25 % of old treats every three days, simultaneously lowering meal kibble to offset calories. Add a spoon of canned pumpkin to support microbiome transition and firm up stools without adding significant calories.
Vet and Nutritionist Insights on Long-Term Use
Board-certified veterinary nutritionists caution against liver exceeding 5 % of total daily intake for months on end; hypervitaminosis A can cause new bone formation around joints. Schedule bloodwork every 12 months if you train daily, monitoring serum vitamin A, ALP, and bile acids for hepatic workload.
Trends to Watch in 2025: Functional Coatings, Probiotics, and Traceability Tech
Expect nano-coated liver cubes infused with postbiotics for gut-brain axis support and QR-code batch tracking that geofarms the pasture of origin. Early trials of collagen-wrapped liver strips claim 30 % slower chew time, ideal for impulse-control drills.
