Crumps' Naturals Beef Liver Bites Review

Intro — why I tested these (and who I’m writing to)

I chase good treats. As a pet parent and gear nerd, I’m constantly trying snacks that are small, high-value, and clean on the ingredient list so I can use them for training and as meal toppers without a lot of filler. Crumps' Naturals Beef Liver Bites put themselves forward as a very simple offering: freeze-dried, single-ingredient beef liver made in Canada. I bought a bag and ran them through the typical gauntlet — recall training sessions, food puzzles, pocket use on walks, and baiting shy dogs — and also paid attention to the less glamourous details: packaging, dust and crumbs, and how older or toothless mouths handled them.

What it is — first look and the official facts

Here’s what the listing and product specs make plain:

• Product: Crumps' Naturals Beef Liver Bites in a small bag (listed unit count/pack size around 4.8 ounces; the listing also shows item weight and product dimensions in a couple of fields).
• Formulation: The listing emphasizes a single-ingredient approach and repeatedly calls the bites "100% Canadian Beef Liver," freeze-dried in small batches.
• Key claims: grain-free, corn-free, soy-free, wheat-free, gluten-free, additive-free, no preservatives, no colours, high protein. The product is also labelled as suitable for all life stages and recommended for training, older dogs, and small dogs.
• Texture and processing: freeze-dried; texture described as both "flexible and crunchy," and also "soft and palatable" in the product's feature bullets.
• Extra ingredients note in the specification: an ingredient line mentions inclusion of ground oyster shells to help with plaque removal.
• Manufacturing and origin: made in Canada, produced in small batches by The Crump Group, Inc.
• Container: sold in a bag; the listing highlights small-batch production and satisfaction guaranteed.

That’s the high-level fact set I used as the foundation for everything that follows. Any practical notes I offer are grounded in long-term hands-on use and in the owner experience themes I tracked while testing.

In daily use — hands-on testing and real-world fit

I used Crumps' Naturals Beef Liver Bites as I would any premium training or high-value treat: pocket-ready during walks, in my training pouch for recall and focus work, sprinkled as a topper during picky phases, and mixed into treat-dispensing toys. Across those use cases the treats earned their keep, but also exposed a few trade-offs you should consider before buying.

How my dogs reacted

• High palatability: these are attention-grabbers. When the bag rustled, dogs came running — from my big mutt to a fussy terrier. For me that translates directly into a training asset: they refocused an otherwise distracted dog in one or two bites.
• Great for picky eaters and short-term appetite loss: during a spell where a dog was off wet food, a handful of these got her to eat and brightened her interest in food for the day. I also used them as a topper for meals with a reluctant cat and saw similarly positive interest.
• Perfect portion size for training: the bite-sized cubes work well for quick reinforcement; I could hand out two or three during a session without a long chewing time or a big interruption.

Pocket, pouch and toy behavior

• Easy to fumble from a bag: because the treats are airy and light, I occasionally missed my target when trying to toss one quickly — not a deal-breaker, but worth noting if you need crisp, flinging-friendly kibble-like pieces.
• Work in puzzle toys: they fit into snuffle mats and many treat-dispensing toys nicely and kept the dog engaged.
• Hand smell and crumbs: handling these can leave a noticeable meat scent on your fingers, and the freeze-dried nature produces some dust/crumbs in the bag, especially along the bottom. I washed my hands after repeated handling and stored the bag upright to keep the shards to a minimum.

How they worked for different life stages

Puppies

• Excellent for puppy training: small size and strong aroma made them effective as high-value rewards during early learning.

Adult dogs

• Adult dogs responded with enthusiasm — good for quick reinforcement, food puzzles, and casual rewarding on walks.

Older dogs and dogs with dental issues

• Mixed results: the listing markets the bites as "soft and palatable" and "great for older dogs," and some senior dogs handled them just fine. However, in my testing and in a number of long-term owner accounts, fully toothless dogs struggled with the texture — one owner reported the treat was not soft enough for a toothless senior. My takeaway: they’re a softer freeze-dried option than crunchy biscuits, but not guaranteed to be suitable for dogs with no teeth.

Materials & build quality — ingredients, processing, and packaging

For a consumable, "build" becomes ingredient transparency, processing method, and packaging performance. Here’s how Crumps' Naturals stacks up by the listing details and long-term use notes.

Ingredients & formulation

• Primary ingredient: the marketing and description call these "100% Canadian Beef Liver," and the product is repeatedly described as single-ingredient and all-natural.
• Ingredient note: the specification also lists ground oyster shells being included to help with plaque removal. The listing therefore contains both the single-ingredient/100% liver claim and a specification item mentioning ground oyster shells; if you need absolute clarity on the exact ingredient statement printed on the bag, double-check the current package or contact the manufacturer.
• Allergen and diet claims: the product is labelled grain-free, corn-free, soy-free, wheat-free, gluten-free, additive-free, and high in protein. It’s also listed under an "Animal Food Diet Type" as special diet in the product fields.

Processing — freeze-dried

• Freeze-drying preserves aroma and concentrates flavor, which is why these act as such strong lure treats.
• Freeze-dried texture contributes to the crumbly dust and lightness noted above; that’s normal for this processing method but affects how the bag holds up in transit and storage.

Packaging notes

• Sold in a bag and packed in small batches. Multiple owner experiences noted shards and a "dusty" bottom layer when the bag arrived, so some settling/crumbly breakage seems common.
• Listing shows a few different weight/pack fields (unit count around 4.8 oz; some fields list a slightly different item weight). If exact weight or volume matters for your use (bulk buying, calorie tracking), check the current package labeling before purchasing.

Safety considerations

Safety is non-negotiable. The good news: there are no explicit toxic-material flags in the listing, but a few practical points deserve attention.

• Ingredient transparency: the product claims single-ingredient 100% Canadian beef liver, but the specs also mention ground oyster shells. If your dog has a shellfish sensitivity, that is something to verify directly on the physical bag or with the manufacturer — the listing itself contains both claims.
• Choking & dental fit: freeze-dried bites are small and generally low-risk for choking when given one at a time to a supervised dog. That said, one long-term owner report flagged that a completely toothless senior couldn’t handle them, so don’t assume they’re safe for dogs who have very limited chewing ability.
• Calorie tracking: the listing doesn’t publish a calories-per-treat number in the fields I reviewed, and there’s an owner-reported discrepancy between previous and current bags’ calorie labeling (one owner noted a change from 3 kcal to 8 kcal per treat shown on the bag). If you’re managing weight, check the bag’s nutrition label or consult the manufacturer for the current calories-per-piece.
• Handling smell and crumbs: the meat scent can linger on hands, and freeze-dried shards can be present in the bag. If your routine requires scentless handling (service-dog settings, scentwork training), this may be a consideration.
• Storage and freshness: the listing notes small-batch production but does not list a guaranteed shelf life or best-by date in the product fields I used. Keep the bag sealed and stored according to standard practice for freeze-dried treats and verify expiration on the package.

Who this is for — and who should skip it

Matching treats to your dog is about size, dental status, training habits, and ingredient needs. Here’s a quick decision grid based on the listing facts and my long-term experience.

Who should strongly consider these

• Owners who want a single-ingredient, freeze-dried treat: the product repeatedly touts the single-ingredient and 100% Canadian beef liver positioning.
• People training puppies or adult dogs who need high-value rewards: the bites are small, aromatic, and work well for repeated reinforcement.
• Owners of picky eaters or dogs with food sensitivities: the grain-free, corn/soy/wheat-free labeling and limited ingredient claims make this an attractive option for elimination or simple-ingredient strategies.
• Small-breed owners who need compact treats: the cube size and light weight are convenient for pocket carry and frequent rewarding.

Who should skip or be cautious

• Dogs without teeth, or dogs that do best with very soft, moist treats: while labeled "soft and palatable," some toothless seniors found these too crisp.
• Owners who cannot tolerate strong meat odors on their hands: handling can smell strongly of liver.
• People strictly tracking calories: because of a reported discrepancy on bag labeling and no clear kcal-per-treat value in the listing fields, double-check the current bag’s nutrition panel before using them as a primary training treat on a calorically restricted dog.
• Those who need a sealed, non-crumbly package during shipping or long storage: freeze-dried treats are fragile and the bag often contains some dust or shards.

Verdict — final take and how I’d use them going forward

Crumps' Naturals Beef Liver Bites hit the core brief for a high-value, limited-ingredient treat: intense aroma, clear single-ingredient marketing, freeze-dried texture, and small portion sizing that’s nearly tailor-made for training. In my household they became my go-to when I needed fast, reliable focus during short training windows or a meal topper to coax a picky eater.

That said, they’re not flawless. The freeze-dried texture makes the bag vulnerable to crumbs and dust, handling leaves a strong meat scent, and a minority of older, toothless dogs may find them too firm. The listing also contains a small contradiction in ingredient messaging (100% beef liver vs. a specifications note about ground oyster shells), and an owner account described a change in per-treat calorie labeling between batches — if you’re managing a medical diet or strict calorie plan, confirm the current nutrition panel on the bag.

If you want a simple, single-ingredient, high-aroma training reward or topper and you're not dealing with a toothless dog or a strict low-odor requirement, these are worth a try. I’ll keep a couple of bags in different places around the house for training sessions and for those moments when I need to get a picky mouth to eat something.

Check before you buy — quick checklist

• Confirm the current bag's ingredient panel if you have shellfish allergies or sensitivities (the spec mentions ground oyster shells in one field).
• Check the nutrition label on the bag for calories-per-treat if you need exact calorie tracking — the listing does not provide a clear kcal-per-piece number and owner experiences reported inconsistencies between bags.
• Decide if the freeze-dried texture is suitable for your dog’s dental status; toothless dogs may struggle.
• Expect meat odor on your hands after handling and some crumbs/shards inside the bag; plan storage accordingly.
• Note that the listing states these are made in Canada and produced in small batches (verify packaging date/expiration on the physical product for freshness).

Colors and packaging (what the listing images suggest)

The listing images show the product in its packaging and the natural color of the freeze-dried liver pieces. The listing does not advertise alternate colorways or multiple packaging color options.

• packaging: natural/tan (as shown in product photos)
• product: freeze-dried brown (actual liver pieces)

Final notes

Simple, strong, and effective — that’s how I’d summarize Crumps' Naturals Beef Liver Bites. For training, picky eaters, and anyone who wants a short ingredient list, they deserve a spot in your treat rotation. Just mind the handling odor, the crumbs, and the occasional package inconsistency; for most households those are small trade-offs for a very dog-friendly, high-value treat.
