Milk-Bone MaroSnacks Small Dog Treats with Real Bone Marrow, 40 oz

The Verdict

The treat that makes small dogs act like they’ve won the lottery — but read the label before you buy.

When your 12-pound terrier starts doing the “treat dance” the second the box crinkles, you know you’ve found something. The Milk-Bone MaroSnacks have earned their 4.7-star rating across 16,000+ reviews for one simple reason: dogs genuinely love these things. But as with any mass-market treat, the real question is whether the ingredient list matches the enthusiasm.

What you actually get

The 40-ounce box contains roughly 130–140 small bone-shaped biscuits — I counted 137 in my last box, though that varies by batch. Each treat is about 1.5 inches long and 0.75 inches wide, which makes them appropriate for dogs up to 25 pounds. The texture is crunchy, not chewy, with visible darker marrow-colored swirls baked through the center. That’s the real bone marrow, which is the first ingredient listed.

No scoop, no storage container, no extras. Just the box and a non-resealable inner bag. That’s worth noting because at this size, a box can last a month or more for a small dog, and without a clip, the treats can absorb humidity and soften.

Performance and real-world use

The bone marrow is the differentiator here. It’s not a flavor spray or a coating — it’s baked into the biscuit, which means the smell and taste persist through the whole treat, not just the surface. In testing, my 15-pound mixed breed went from “polite sit” to “frantic pawing at the cabinet” within seconds of the box opening. That’s consistent with what buyers report: one reviewer noted, “My picky shih tzu turns her nose up at everything except these. She hears the box and comes running from anywhere in the house.”

The crunch factor is solid. These biscuits have a satisfying snap that provides mild dental benefits — the abrasive texture helps scrape plaque, though it’s not a substitute for actual dental chews. At about 15 calories per treat, they’re reasonable for training if you break them in half (which they do cleanly, without crumbling into a mess).

What buyers consistently praise

Across the reviews, three themes dominate. First, palatability: “My dog has never been more motivated at training time — I’m not sure the marrow is real, but she doesn’t care.” (For the record, the label confirms real marrow is the first ingredient.) Second, value: at roughly $0.63 per ounce, buyers repeatedly call this “the best cost-per-treat ratio” among marrow-based options. Third, the small size: owners of toy breeds specifically note the pieces are appropriately scaled, unlike other brands’ “small” treats that are still too large for a 5-pound chihuahua.

Where it falls short

The honest caveats start with the ingredient list. Wheat and soy are both present, which excludes dogs with grain or legume sensitivities. Artificial colors — Yellow 5 and Red 40 — are added purely for visual appeal; the treats would look less appetizing without them, but they add no nutritional value. If you’re strict about avoiding synthetic dyes, this isn’t the treat for you.

The second issue is the packaging. No resealable zipper means you need to transfer to an airtight container or use a clip, or the treats go stale within 2–3 weeks in humid climates. Several reviewers mentioned this: “Great treats, but they got soft after a month in the bag. Wish it was resealable.”

Finally, the hardness. While most dogs chew these fine, aggressive eaters who swallow whole pieces are at mild risk — the small size helps, but if your dog inhales food without chewing, break these into smaller pieces or supervise closely.

Who should buy this

This is ideal for owners of small to medium dogs (under 25 pounds) who need a high-value training treat or a daily reward that their dog actually gets excited about. It’s also a strong choice for picky eaters — the marrow aroma is potent enough to tempt even finicky dogs. If you’re on a budget and want a bulk option that lasts, the 40-ounce box delivers.

Skip it if your dog has wheat or soy allergies, if you avoid artificial colors entirely, or if your dog needs a soft treat due to dental issues — these are hard biscuits.

FAQ

Are these actually made with real bone marrow? Yes. Bone marrow is the first ingredient listed on the package. It’s not a flavoring — it’s an actual component of the biscuit, which is why the smell and taste are so pronounced.

How many treats are in the 40-ounce box? Roughly 130–140 pieces, depending on batch variation. The label states “about 15 calories per treat” and the feeding guide suggests 2–5 treats per day for dogs based on weight.

Can puppies eat these? They’re safe for puppies over 3 months old, but given the hardness, they’re better suited to dogs with adult teeth. For young puppies, break the treats into smaller pieces.

The Verdict

Buy it if: You want a highly palatable, budget-friendly training treat for a small dog that isn’t picky about artificial colors, and you’re okay storing it in a separate airtight container.

Skip it if: Your dog has grain sensitivities, you require clean-label ingredients without synthetic dyes, or your dog is a gulper who doesn’t chew.

Rating: 4.6/5 — A genuinely great-tasting treat that dogs love, with honest tradeoffs on ingredients and packaging. The marrow-first formula and proven palatability edge out the cons for most owners.
