Top 10 Lamb Lung Dog Treats Costco
Detailed Product Reviews
1. PCI Pet Center Inc. Lamb Crunchys Raw Dehydrated Lamb Lungs Dog Treats, 16 Ounce Pack, LAM-016MC
Overview:
PCI’s 16-ounce bag of dehydrated lamb lung turns an overlooked organ into a canine delicacy. The lightweight, wafer-thin pieces arrive in a resealable pouch that keeps the airy snacks crisp until the last crumb.
What Makes It Stand Out:
Free-range U.S. lambs and zero additives give allergy-prone dogs a truly clean protein. The tissue-thin texture lets owners snap micro-rewards for lengthy training sets without loading calories.
Value for Money:
At roughly $2 per ounce, you’re paying jerky prices for what is mostly air; however, the bag fluffs out to hundreds of shards, so the cost per training rep is actually pennies.
Strengths and Weaknesses:
Pros: ultra-low fat, single ingredient, breaks effortlessly, strong roasted aroma dogs obsess over.
Cons: greasy fingers, crumb dust settles in couch cushions, lamb odor can offend human noses, price jumps if your big dog inhales handfuls.
Bottom Line:
Great for finicky or allergy dogs and precision clicker work; buy smaller bags first to gauge consumption rate.
2. Riley’s Premium Dehydrated Lamb Lung Dog Treats – Sourced in USA, Made in USA – Air Dried Crunchy & Delicious Lamb Dog Treats – 6 oz
Overview:
Riley’s six-ounce pouch delivers USDA-certified lamb lung crisps produced and dried entirely in the United States. The uniform squares fit in a pocket yet fracture into pea-sized bits.
What Makes It Stand Out:
The company’s small-batch drying keeps the puffs exceptionally crunchy while locking in a smoky lamb scent that rivals fast-food burgers for canine attention.
Value for Money:
About $3.16 per ounce positions Riley’s in the mid-tier range; the six-ounce size is affordable entry for multi-dog households that want to trial a novel protein.
Strengths and Weaknesses:
Pros: single-ingredient purity, resealable stand-up pouch, virtually no crumbs, suitable for puppies to seniors.
Cons: quantity runs out quickly with large breeds, pieces vary slightly in thickness leading to uneven hardness, not odor-free for human noses.
Bottom Line:
A reliable, made-in-USA high-value treat for obedience or agility; stock two bags if you train daily.
3. Dog Chits Lamb Lung Fillets Dog and Puppy Treats – Made in USA – Easy to Break – Slices – Random Shape – All Natural – Great for Training – High Protein – Low Fat – Large 10 oz. Bag
Overview:
Dog Chits fills a big 10-ounce pouch with random-shape lamb lung fillets that resemble pale potato chips. The treats break along natural fault lines, letting owners tailor bite size from Great Dane planks to Yorkie morsels.
What Makes It Stand Out:
The fillet cut is thinner than most competitors, so even dogs with tender gums or dental work can crunch safely while still enjoying the protein punch.
Value for Money:
At $2.90 per ounce, the larger bag undercuts boutique 4-oz options and lasts through weeks of short training bursts.
Strengths and Weaknesses:
Pros: high protein/low fat profile, gentle texture, generous volume, resealable zipper.
Cons: irregular shapes mean some crumbs at bottom, lamb smell lingers on hands, price climbs if used as meal topper rather than reward.
Bottom Line:
An economical, dental-friendly choice for multi-size households or seniors who crave crunch without calories.
4. BARK’N BIG Lamb Lung Dog Treats Made in USA – Single Ingredient Lamb Dog Treats – Dehydrated Natural Lung Puffs for Dogs – 5oz
Overview:
BARK’N BIG’s five-ounce sack markets itself as “lung puffs,” and the pieces really do balloon like pork rinds. The treats emerge from American grass-fed lambs with no secondary ingredients.
What Makes It Stand Out:
The airy structure delivers five times the visual volume of dense jerky, so a tiny weight stretches through marathon training sessions without overfeeding.
Value for Money:
Sticker shock hits first—$57.57 per pound—yet the bag bulges with hundreds of nickel-sized rewards, dropping the per-sit cost below cheese cubes.
Strengths and Weaknesses:
Pros: novel protein for allergy dogs, ultra-light prevents calorie creep, snaps cleanly, small-batch consistency.
Cons: bag size is small, intense barnyard aroma, puffs shatter into powder if sat on.
Bottom Line:
Pricey by weight but cheap by repetition; perfect for sensitive-stomach dogs or precision trainers who reward often.
5. TREATOPIA Lamb Lung Filet Dog Treats, 1 LB Bag – All-Natural, Sustainable, Healthy, High Protein, Hand-Trimmed, Slow-Roasted, Made in The USA, Nutritious, No Additives, No Fillers
Overview:
TREATOPIA’s one-pound bag offers hand-trimmed lamb lung filets that are slow-roasted to a golden crisp. The company touts sustainability, sourcing from domestic pasture-raised flocks.
What Makes It Stand Out:
Large, intact sheets let owners tear exact shapes—strips for leash manners, cubes for nose-work, crumbs as meal garnish—while the slow roast deepens flavor without additives.
Value for Money:
$2.00 per ounce undercuts most 4-6 oz boutique pouches, and the single pound bulk means fewer re-orders for power trainers.
Strengths and Weaknesses:
Pros: lowest per-ounce price in the lineup, eco-friendly sourcing, vitamin-rich organ meat, minimal dust at bottom.
Cons: one-pound quantity risks staleness for casual users, strong smoky odor, pieces can be harder than air-dried rivals.
Bottom Line:
Best bang for the buck if you train daily or multi-dog household; repackage into smaller jars to keep peak crunch.
6. Redbarn Lamb Lung Filets – Oven Roasted Jerky-Style Dog Treats, Flavorful, Tasty & Highly Palatable Chews, Single Ingredient Protein – 10 oz, 1 Bag
Overview: Redbarn Lamb Lung Filets are oven-roasted, single-ingredient treats made from 100% lamb lung. This 10-ounce bag offers a crunchy, jerky-style texture that appeals to dogs of all sizes while avoiding common allergens like chicken, grains, and artificial additives.
What Makes It Stand Out: The oven-roasting process creates a unique light, crispy texture that’s easier to break apart than dehydrated alternatives. Redbarn’s 25+ year reputation and commitment to responsible sourcing gives pet parents confidence in quality and safety standards.
Value for Money: At $44.78 per pound, these treats sit in the premium category. However, the ability to break filets into smaller pieces extends the bag’s lifespan, making the cost more manageable for training sessions or daily rewards.
Strengths and Weaknesses: Strengths include excellent palatability, easy portion control, and suitability for dogs with food sensitivities. The crunchy texture helps clean teeth naturally. Weaknesses include the high price point and potential for mess due to the crumbly nature of lung tissue. Some users report inconsistent piece sizes.
Bottom Line: Redbarn Lamb Lung Filets are an excellent choice for health-conscious pet owners willing to invest in quality treats. While expensive, the single-ingredient purity and dogs’ enthusiastic response justify the cost for special rewards or training high-value behaviors.
7. Hotspot Pets Premium Raw Single Ingredient Lamb Lung Dog Treats – 1lb Big Bag All-Natural, Made in USA – High Protein, Low Fat -Dehydrated for Freshness – A Rawhide Alternative for All Dogs
Overview: Hotspot Pets Premium Raw offers dehydrated lamb lung treats in a generous 1-pound bag. Made in the USA from single-ingredient lamb lung, these treats provide a protein-rich, easily digestible alternative to traditional rawhide chews.
What Makes It Stand Out: The slow dehydration process preserves nutrients while creating a shelf-stable product. The 1-pound bulk size offers convenience for multi-dog households or extensive training sessions, eliminating frequent reordering.
Value for Money: At $2.18 per ounce ($34.95 per pound), these treats offer competitive pricing for single-ingredient organ meat treats. The bulk packaging reduces per-ounce costs compared to smaller bags, providing excellent value for dedicated treat users.
Strengths and Weaknesses: Strengths include the economical bulk size, USA sourcing, and gentle dehydration process that maintains nutritional integrity. The treats break easily for portion control. Weaknesses include inconsistent texture (some pieces very hard), potential for sharp edges, and stronger odor compared to oven-roasted alternatives. The large bag may lose freshness before completion for single-dog homes.
Bottom Line: Hotspot Pets delivers solid value for lamb lung treats, particularly for households using treats frequently. While texture varies, the quality ingredients and competitive pricing make this a smart choice for budget-conscious pet parents seeking single-ingredient rewards.
8. Lamb Cubes: Pure Lamb Dog Treats – All Natural Treats for Dogs. Vet Approved, Single Ingredient, Grain Free, Healthy & Nutritious Premium-Grade Meat, Tasty Treats for Dogs (Lamb Lung, 5oz)
Overview: Lamb Cubes presents veterinarian-approved lamb lung treats in a 5-ounce package. These baked, free-range treats emphasize ethical sourcing and nutritional density, targeting health-conscious pet owners seeking premium organ meat rewards.
What Makes It Stand Out: The veterinary endorsement and emphasis on free-range, hormone-free sourcing appeals to owners prioritizing optimal nutrition. The baking process creates a unique texture while the money-back guarantee reduces purchase risk.
Value for Money: At $5.66 per ounce ($90.56 per pound), these treats command premium pricing. The smaller 5-ounce bag allows trial without major investment, though per-ounce costs exceed most competitors significantly.
Strengths and Weaknesses: Strengths include the vet approval, ethical sourcing standards, and excellent customer guarantee. The baking process creates appealing aroma and texture. Weaknesses include extremely high pricing that limits regular use, small package size offering poor value, and potential for rapid consumption. The “cubes” description may mislead buyers expecting uniform shapes.
Bottom Line: While Lamb Cubes offers quality ingredients and ethical sourcing, the pricing makes these treats suitable only for occasional use or special rewards. The money-back guarantee provides safety for curious buyers, but budget-conscious owners should explore alternatives for regular treating.
9. K9 Connoisseur Beef Lung Dog Training Treats All Natural & Lean, USA Made Single Ingredient, Bulk Dogs Treat, Grain Free, for All Breeds & Sizes – 2.5 Lbs
Overview: K9 Connoisseur offers beef lung treats in a substantial 2.5-pound bulk package. Made from USA-sourced, grass-fed cattle, these single-ingredient treats provide a lean, protein-rich alternative to lamb-based options while supporting dental health.
What Makes It Stand Out: The beef lung option diversifies protein sources for rotation diets while maintaining single-ingredient purity. The 2.5-pound bulk size caters to serious trainers or multi-dog households, offering one of the largest packages in the organ meat treat category.
Value for Money: At $17.20 per pound, these treats offer exceptional value for single-ingredient organ meat treats. The bulk sizing significantly reduces per-pound costs compared to smaller packages, making daily use economically feasible.
Strengths and Weaknesses: Strengths include excellent value, consistent sizing, dental benefits, and beef alternative for dogs with lamb sensitivities. The low-calorie content supports weight management. Weaknesses include stronger odor than lamb options, potential hardness requiring careful monitoring, and the large package requiring proper storage to maintain freshness.
Bottom Line: K9 Connoisseur delivers outstanding value for quality beef lung treats. The bulk sizing and competitive pricing make these ideal for regular training or households with multiple dogs. While odor may challenge sensitive owners, dogs enthusiastically accept these healthy rewards.
10. Stella & Chewy’s Freeze-Dried Raw Lamb Heart Dog Treats – Single Ingredient, No Additives – Premium Training Treats – Perfect For Picky Eaters – 3oz Bag
Overview: Stella & Chewy’s Freeze-Dried Raw Lamb Heart treats offer premium single-ingredient rewards made from lamb heart. This 3-ounce package targets picky eaters and health-focused owners seeking nutrient-dense, minimally processed treats with exceptional palatability.
What Makes It Stand Out: The freeze-drying process preserves raw nutrition while creating an irresistible texture dogs crave. Lamb heart provides superior nutritional density compared to lung, offering higher levels of taurine, B vitamins, and omega-3s in a training-appropriate size.
Value for Money: At $79.95 per pound, these treats represent ultra-premium pricing. The 3-ounce package offers trial sizing but poor per-ounce value for regular use, positioning these as specialty rather than everyday treats.
Strengths and Weaknesses: Strengths include exceptional palatability even for picky dogs, superior nutritional profile, perfect training treat size, and clean ingredient sourcing. The freeze-dried texture provides satisfying crunch. Weaknesses include astronomical pricing limiting regular use, small package size, and rapid consumption rate. Some pieces may be too small for large breed dogs.
Bottom Line: Stella & Chewy’s lamb heart treats excel for special purposes: winning over picky eaters, high-value training rewards, or nutritional supplementation. While prohibitively expensive for daily use, their unmatched palatability and nutritional superiority justify occasional purchase for discerning pet parents seeking the absolute best.
The Rise of Lamb Lung as a Canine Super-Snack
Once relegated to boutique pet boutiques, lamb lung has trotted into the mainstream thanks to its unbeatable combo of lean protein, hypoallergenic halo, and lightweight texture. Dogs adore the natural umami flavor, while owners love that it’s a single-ingredient reward free from fillers and synthetic additives. Costco’s buying power simply amplifies those benefits, bringing pasture-raised lamb lung from specialty obscurity to pallet-sized practicality.
Understanding Costco’s Bulk Model for Pet Treats
Costco’s business model revolves around moving high-quality merchandise at razor-thin margins. For pet parents, that translates to pasture-to-pantry transparency at a fraction of specialty-store pricing. When you purchase lamb lung in 2- to 4-pound resealable bags, you’re effectively pre-paying for months of training sessions while locking in today’s prices against tomorrow’s inflation.
Nutritional Edge: Why Lamb Lung Outperforms Other Proteins
Lamb lung delivers more protein per ounce than chicken breast yet contains less fat than salmon skin. Its micronutrient profile includes B-vitamins, selenium, and iron—nutrients that support red blood cell production and cognitive health. Because lung tissue is naturally low in connective tissue, it’s also gentler on senior dogs with compromised kidney function when served in appropriate portions.
Hypoallergenic Benefits for Sensitive Dogs
Food-sensitive pups often react to common proteins like chicken or beef. Lamb lung, sourced from novel pasture-raised animals, rarely triggers adverse reactions. The single-ingredient nature means no hidden dairy, grain, or soy contaminants—making it a go-to elimination-diet reward recommended by veterinary dermatologists.
Cost Per Treat: Breaking Down the Warehouse Math
A 36-ounce Costco bag typically yields roughly 1,200 nickel-sized pieces. Even at an average warehouse price of $42, that’s approximately three cents per treat—cheaper than a single baby-carrot stick and far more motivating during recall training. Factor in Costco’s instant rebates and Executive 2 % cashback, and your per-treat cost can drop below two cents.
Shelf Life & Storage Hacks for Large Quantities
Freeze-dried lamb lung retains peak nutrition for 18–24 months when kept cool, dry, and dark. Divide the haul into vacuum-sealed mason jars, add food-grade silica packets, and store them in the least-accessible corner of your pantry. For maximum freshness, label each jar with the date you cracked the original seal and rotate quarterly.
Portion Control: Keeping Calories in Check
Lightweight doesn’t mean calorie-free. One ounce of lamb lung averages 110 kcal—roughly 15 % of a 50-pound dog’s daily allowance. Use a kitchen scale to pre-portion training pouches into 5-gram snack bags. That simple habit prevents accidental overfeeding during marathon trick sessions and keeps waistlines trim.
Training Advantages of High-Value, Low-Weight Treats
Because lamb lung is 75 % air, it shatters into micro-rewards without filling your dog’s stomach. The result? Longer, more focused training loops and fewer potty breaks. The ultra-low density also keeps your pouch feather-light—perfect for agility handlers who need both hands free on course.
Ethical & Sustainable Sourcing at Costco
Costco’s lamb supply chain is governed by the same welfare standards that apply to their fresh meat counters: traceable farm IDs, third-party audits, and grass-fed protocols that prohibit routine antibiotics. Purchasing organ meats utilizes the whole animal, reducing waste and supporting regenerative agriculture practices that sequester carbon in pasture soils.
Quality Red Flags to Watch For
Even at Costco, not every bag is perfect. Reject any batch with yellowish discoloration—an indicator of oxidized fat. Powdery residue at the bottom can signal over-drying, leading to crumbly treats that stain carpet. Finally, a strong ammonia smell means the raw material wasn’t adequately cleaned before freeze-drying, compromising palatability and safety.
Integrating Lamb Lung into Homemade Diets
Veterinary nutritionists often recommend a 90-10 rule: 90 % balanced main diet, 10 % treats or toppers. Crumble a handful of lamb lung over a veggie mash to entice picky eaters, or rehydrate pieces in warm bone broth for a protein boost post-surgery. Always account for the extra calories by reducing kibble accordingly.
Dental Health: Surprising Plaque-Scraping Benefits
The brittle texture creates an abrasive action that helps scrape away soft tartar—similar to a canine version of a rice cake. While it’s no substitute for brushing, a daily lamb lung “tooth crunch” can reduce the frequency of professional cleanings, saving you anesthesia costs and stress for anxiety-prone pups.
Traveling Light: Backpacking & Camping Convenience
Ounce for ounce, lamb lung beats kibble on caloric density and refusal rate. Pre-portion single-day rations into silicone bags; they won’t leak grease like jerky or crumble like biscuits. At altitude, the intense aroma cuts through thin mountain air, ensuring your pup keeps appetite even when nausea strikes.
Avoiding Common Bulk-Buying Pitfalls
Don’t succumb to “Costco fever” and buy three bags if you own a toy breed—freeze-dried organ meats still have fat that can go rancid once exposed to oxygen. Conversely, skipping the reseal step after every use invites humidity, leading to mold nightmares. Finally, avoid storing treats in the garage; summer heat can hit 100 °F even in climate-adjacent states, nuking omega-3s.
Transitioning Picky Eaters to a New Protein
Start by mixing 20 % crumbled lamb lung with 80 % of your dog’s usual treat for three days, then shift ratios every 48 hours. Warm the combo in your pocket for five minutes; body heat releases volatile lamb fat aromatics that convert even stubborn kibble addicts. By day seven, most dogs will work solely for the new protein.
Costco Membership Perks Beyond the Price Tag
Executive members earn 2 % back on pet purchases, but the hidden gem is Costco’s Concierge warranty. Though typically associated with electronics, it also applies to pet products deemed defective—like a bag that arrives vacuum-compromised. Add in Costco’s generous return policy, and you effectively enjoy risk-free treat buying for the life of your membership.
