Greenies Blueberry Large Dog Dental Treats Review

Intro

Hey — The Pet Dude here. I live for gear and treats that actually do the job without turning my kitchen into a science experiment. Greenies Blueberry large dental chews are one of those products that comes with a lot of claims: qualified professional-recommended, designed to clean down to the gumline, and clinically shown to reduce tartar and plaque by specific percentages in 28 days. I dug into the listing details, the product specs, and my compilation of owner experience notes to see how these chews perform in the real world for adult large-breed dogs. This review sticks to what the listing and my research notes actually say — no made-up numbers, no medical advice, just the facts and what owners in my notes experienced.

What it is / first look

Greenies Blueberry Large Dog Dental Treats are a pouch of -focused dental chews made by Mars Petcare US. The specific pack I looked at comes as a 12-ounce pouch that lists an 8-count format in the product title; the listing also identifies the item form as a bone and the product as intended for dental care.

The listing leads with an oral-health focus: Greenies say these chews were crafted to support the four areas professionals check most — plaque, tartar, gums, and breath — and the copy cites a claim that their dental chews reduce tartar by 47% and plaque by 40% in 28 days (Data on file). The brand also highlights that the chews are qualified professional-recommended, are made with natural ingredients plus vitamins, minerals and nutrients, and are rawhide-free.

Key listing facts at a glance:

• Manufacturer: Mars Petcare US
• Product: Greenies Blueberry Flavor Large Dog Dental Chews
• Pack size noted in title: 12 ounces, 8 treats
• Intended for: adult dogs; breed recommendation: large breeds (made for dogs between 50–100 lb.)
• Claims: qualified professional-recommended; reduces tartar and plaque by the percentages above in 28 days (Data on file); rawhide-free; bendable/won't snap

The listing also lists other flavor/pack options beyond Blueberry, which I note below since flavor choice matters to picky dogs.

Available flavors and packs

The listing presents multiple flavor and pack choices. Based on the product pages and image filenames, available flavors and variety pack options may include:

• Blueberry (this review)
• Gingerbread
• Mint
• Original
• Sweet Potato
• Pumpkin Spice
• Variety packs: Original/Blueberry/Mint and Original/Blueberry/Sweet Potato

In daily use

I approached daily-use observations in two ways: what the listing promises about performance and what my research notes from actual dog owners showed. The listing positions Greenies as a daily dental chew that integrates into an oral-care routine. The brand copy specifically says the design "works like a toothbrush to clean down to the gumline" and supports breath and oral health maintenance.

Palatability and how dogs take to them

Palatability is a major factor for dental chews — if the dog won’t eat it, it can’t help dental health. In my research notes, a strong positive theme was how many dogs absolutely love these chews. Multiple notes say dogs went nuts for the blueberry flavor, some owners called them a favorite treat, and several people said their dog whines in the morning until they get one. That aligns with the listing’s focus on flavor and reward.

That said, palates vary. One of my notes flags that some owners bought the large size and then realized it was too big for their dog’s comfort — they recommended choosing the correct size. If you have a smaller adult dog, the listing does show other sizes and variety packs, so pick the size that matches your dog's weight (the large size is made for dogs 50–100 lb.).

Portioning and how owners actually give them

Daily feeding instructions are not spelled out in the listing copy beyond the product being intended for adult dogs and the manufacturer recommended age of 1 month and up. However, my research notes show many owners divide a large chew into halves to make them last longer or to adjust portion size. Several notes specifically mention breaking a large Greenie in half for daily use.

Practical points: smell, bag handling, and freshness

Two practical themes came through in my notes. First, the aroma is polarizing — some owners say the blueberry scent is almost pleasant, while others call the smell awful. Second, one owner noted that the bag was easy to use and resealable, which helps keep treats fresh between servings. The listing itself specifies the container type as a pouch, but it doesn't enumerate resealability in the spec fields; the resealable-bag report comes from my research notes.

Effect on breath and dental signs

The listing gives specific clinical-style claims: 47% less tartar accumulation and 40% less plaque accumulation in 28 days (Data on file). Those numbers are presented as part of the product's clinically proven dental-care messaging. In my research notes, owners commonly reported fresher breath after using Greenies, and some said their dog’s breath noticeably improved — that anecdotal feedback matches the listing’s breath-support claim, at least in the owner experience I collected.

Materials & build quality

For edible products I look at formulation transparency and the chew's physical design. The listing describes the chews as made with "natural ingredients plus vitamins, minerals, and nutrients," but it does not list a full ingredient breakdown or ingredient percentages in the spec fields. The item form is a bone-shaped chew and the copy calls out a "unique texture" that cleans along the gumline; it also claims the chew is bendable and "won't snap."

What that means practically: the chew is intended to be soft or flexible enough to bend rather than shatter, which the listing frames as a safety and digestibility feature. My research notes echo that owners find them easy to chew and digest for many dogs, and the rawhide-free label in the listing is consistent with the idea that these are not traditional rawhide chews.

Because the listing does not include a full ingredient panel in the product facts, I can't say more about specific ingredients, sourcing, or percentages beyond the brand's wording about natural ingredients and added vitamins/minerals/nutrients.

Safety considerations

Pet safety is always first for me. I looked for red flags in the listing and in my research notes.

• Size matters: The listing repeatedly identifies this large size as made for dogs between 50–100 lb. That is the clearest safety and fit guidance the product gives. My research notes contain multiple reminders from owners who ordered the large size and then found it too big for their dog — so double-check weight recommendations before you buy.
• Rawhide-free and digestibility: The listing explicitly says the product is rawhide-free and calls the chews "easy to chew and digest." That reduces some traditional rawhide concerns, but it doesn't eliminate all digestive or choking risks for every dog.
• Flexible—won't snap: The listing claims the chews are bendable and won't snap, which the brand presents as a safety feature. In my notes, owners echoed that the treat is not a hard, brittle chew that shatters.
• Digestive reactions: My research notes include reports of digestive side effects in some dogs. A notable theme: a few owners reported that the chews gave their dog significant gas. One quote in my notes even says, "Great breath, bad gas." Another owner explicitly said the treats didn't give their dog diarrhea, showing that reactions vary by animal. These are important considerations if your dog has a sensitive stomach.
• Gums and aggressive chewing: One note mentions a dog’s gums bleeding when chewing a treat; that owner interpreted it as the chew doing its job. The listing itself claims the design cleans down to the gumline and supports gum health, but the presence of gum bleeding in my notes is a signal to watch your dog the first few times and stop if you see concerning injury. I can’t diagnose or give medical advice — consult a qualified professional if you see bleeding or injury.

Overall, the listing's safety messaging centers on rawhide-free formulation, chew flexibility, and proper sizing (50–100 lb for large). My research notes add real-world nuance: strong palatability, some digestive upset for a minority of dogs, and size-mismatch problems when buyers pick the wrong size.

Who this is for / who should skip

I break this section down by dog size and life stage because the listing gives specific size and age cues.

Best fit: Large adult dogs (50–100 lb)

• The listing explicitly says the large size is made for dogs between 50–100 lb. If your dog falls in that range and tolerates chewy dental treats, this is the stated target.
• The product form and listing call the treats "for adult dogs," and the manufacturer recommended age field shows "1 month and up," but the item is labeled in the title and bullets as an adult dental chew. My recommendation: if your dog is an adult within the 50–100 lb range and you want to include a daily dental chew, this product is a designed match.

Who should skip or be cautious

• If your dog is substantially under 50 lb, the large size will likely be too big — owners in my notes suggest choosing the appropriate size rather than forcing a single size to fit all. The listing includes other sizes and packs, so pick the size that matches your dog’s weight.
• If your dog has a very sensitive stomach or a history of gas or digestive upset, my research notes show this chew gave some dogs noticeable gas. That doesn't mean every dog will react that way, but proceed with caution and try one chew to observe the reaction before making it routine.
• If you’re specifically seeking full ingredient transparency or exact sourcing, the listing provides general wording about natural ingredients plus vitamins, minerals, and nutrients, but it does not present a full ingredient panel in the spec fields. If you need full ingredient detail for allergy or dietary reasons, the listing is not exhaustive in the spec fields and you may want to seek a full ingredient list from the brand or retailer.

Verdict

Here’s how I summarize what Greenies Blueberry large dental chews bring to the table, based strictly on the listing details and my research notes:

• What they do well: Many dogs find them highly palatable — the blueberry flavor is frequently called a hit in owner notes. The listing positions these chews as qualified professional-recommended dental treats that support plaque, tartar, gum, and breath care, and it states specific reductions in tartar and plaque in 28 days (47% tartar, 40% plaque, Data on file). The chews are rawhide-free, described as bendable ("won't snap"), and the listing says they are easy to chew and digest.
• What to watch for: Price sensitivity came up repeatedly in my notes — owners often call them pricey and wish there were more per pouch. Some dogs experienced digestive upset (notably gas) in my compiled notes, and a few owners discovered the large size was too big for their dog. The listing’s ingredient phrasing is positive but not a full ingredient panel in the spec fields, so buyers needing full transparency should verify ingredients through the brand if needed.
• Overall take: For adult dogs in the 50–100 lb range who enjoy chewy dental treats, Greenies Blueberry large chews offer a professionalerinarian-recommended, rawhide-free option designed to support oral health and breath. They’re a solid daily-treat choice if you monitor your dog for digestive reactions and buy the correct size.

Check before you buy (my quick checklist)

• Confirm your dog’s weight—this large size is made for dogs between 50–100 lb.
• Decide if you want the blueberry flavor or a different flavor/variety pack listed by the brand.
• Plan your serving size—owners commonly split a large chew in half to stretch the pouch.
• Watch your dog the first few times for digestive reactions (my research notes include reports of gas).
• If ingredient details are important (allergies or dietary restrictions), the listing says "natural ingredients plus vitamins, minerals & nutrients" but does not include a full ingredient panel in the spec fields — request a full ingredient list if you need it.

FAQ

Q: Are Greenies Blueberry large dental chews safe for my adult dog?

A: The listing states these chews are rawhide-free, easy to chew and digest, and bendable ("won't snap"), and the product is intended for adult dogs between 50–100 lb. My research notes include both positive digestion reports and some reports of gas in a minority of dogs, so watch your dog the first few times and consult a qualified professional if you see concerning symptoms.

Q: Will these treats actually reduce plaque and tartar?

A: The listing claims a 47% reduction in tartar and a 40% reduction in plaque accumulation in 28 days (Data on file) and labels the product as clinically proven. Owner notes in my research often report improved breath, which aligns with the listing's breath-support claim.

Q: What size dog is the large chew for?

A: The listing explicitly says the large size is made for dogs between 50–100 lb and recommends the product for adult dogs. Owners in my notes who picked the wrong size reported it felt too big, so match size to your dog’s weight.

Q: How many treats come in the pouch?

A: The product title and item fields show this pack as a 12-ounce pouch with an 8-count notation in the title ("12 Ounces 8 Treats"). If exact treat count per package is critical, double-check the retailer page for the specific SKU you plan to buy.

Q: My dog has a sensitive stomach — will these give them diarrhea?

A: The listing states the chews are easy to chew and digest and are rawhide-free, but my research notes include mixed reactions: some owners reported no digestive issues, while others reported significant gas. The listing does not guarantee no digestive side effects, so try one chew and observe your dog before making it a daily routine, and consult a qualified professional for health-specific questions.

Q: Are the chews brittle or do they shatter?

A: The listing states the chews are bendable and "won't snap," and owners in my notes described them as soft enough to chew and break into pieces or be halved. That said, always supervise chews to manage any unexpected breakage or aggressive chewing behavior.

That’s the full breakdown. If you want a short comparison to other flavors or sizes in Greenies’ line, I can dig through the specific ingredient panels for those SKUs next — or if you tell me your dog's exact weight and chewing style, I can recommend which size or flavor to try first.
