Things To Consider

• Not intended for adult dogs, large-breed puppies, or non-dog pets

• Large bag may go stale if not stored properly over time

My foster puppy Poppy was a nine-week-old corgi-terrier mix with the appetite of a goat and the digestive system of a houseplant. I’d already burned through two “premium” puppy foods that turned her into a 4 a.m. alarm clock with a mop required. A friend who runs a small-breed rescue in Ohio handed me a Ziploc of her own kibble and said, “Try this before you buy another bag you’ll regret.”

That’s how I ended up feeding NutriSource Small & Medium Breed Puppy Dry Dog Food to Poppy, and later to a rotating cast of fosters. Six bags later, I have opinions — mostly good ones, but not unqualified ones.

Here’s the short version: NutriSource Small & Medium Breed Puppy is a complete-and-balanced puppy formula aimed at small and medium breeds, sold in a 26 lb bag for around $68.25, and it currently holds a 4.7 out of 5 rating across 968 customer reviews. Most of the praise centers on palatability and stool quality; most of the complaints are about the bag size, the price, and people buying it for the wrong dog.

At a Glance

• Best For: Small and medium breed puppies from weaning to roughly 12 months, and multi-puppy households that go through kibble fast.
• Key Benefit: Consistent, highly palatable growth-stage nutrition that most puppies accept without a fight — and that owners say keeps stools firm.
• Rating: 4.7 / 5 from 968 reviews.
• Price Point: $68.25 for 26 lb, which works out to roughly $2.62 per pound — mid-premium territory, not budget, not boutique.
• One-Line Verdict: A reliable, well-liked puppy food that earns its rating, as long as you have a small or medium breed puppy and somewhere proper to store 26 pounds of kibble.

Quick Verdict

Buy it if: You have a small or medium breed puppy (think beagle, corgi, Boston terrier, cocker spaniel, miniature poodle, or a mixed breed in that weight range), you want a food you don’t have to bribe your dog to eat, and you either have multiple puppies or don’t mind committing to a big bag.

Skip it if: You have a large or giant breed puppy, an adult dog, or a puppy with known food allergies or a sensitive stomach that’s already flared up on chicken-based formulas. Also skip the 26 lb size if you have one tiny puppy and no airtight storage — a bag this size can go stale before a 5 lb Chihuahua-mix puppy finishes it.

Key Features & Benefits

The 26 lb bag actually matters — in both directions

Let’s do the math, because this is the part people gloss over. A 10 lb puppy eats roughly 1 to 1.5 cups a day at eight to twelve weeks, tapering as growth slows. At around 3.5 ounces per cup, that’s about 4.5 oz daily, or roughly 90 days from a 26 lb bag for a single small puppy. A medium breed puppy eating twice that will clear it in six to seven weeks.

So for a two-puppy household or a medium breed, the big bag is a genuine money-saver. For one toy-breed puppy, it’s a storage project. More on that below.

Sized and formulated for small and medium breeds specifically

Kibble size is one of those things manufacturers undersell. Small-breed puppies have small mouths and shallow muzzles, and a lot of “all life stages” kibble is simply too big for them to chew comfortably. In my experience with Poppy and two litters of fosters, the pieces here were small enough that even the runtiest puppy in the group managed without me pre-soaking.

The formula is also built around the faster metabolic rate and growth curve of smaller dogs rather than being a one-size-fits-all puppy food.

Complete and balanced growth nutrition

This is an AAFCO-complete puppy formula — meaning it’s designed to be the whole diet, not a topper. You’re not supposed to need supplements, and in practice you don’t. I’ll be honest: I’m not a veterinary nutritionist, and ingredient panels change over time, so I won’t pretend to audit the guaranteed analysis line by line. What I can tell you is that my fosters stayed in good body condition on it, and their vet had no complaints at their 12- and 16-week checkups.

What Pet Owners Are Saying

This is where I spent most of my time, because 968 reviews is a real sample size and the patterns matter more than any single glowing write-up.

What stands out first is palatability. Across the reviews, the single most repeated theme is puppies actually eating it. Not “eventually eating it after a standoff.” Owners describe puppies diving into the bowl, cleaning it, and — crucially — staying interested months in, which is not something you can say about every puppy food. Picky small breeds are a recurring character in these reviews, and this food seems to win most of those battles.

Second is stool quality. This comes up constantly, and it was my experience too. Many owners report firmer, more consistent stools within a week or two of transitioning. If you’ve ever dealt with a puppy on a food that didn’t agree with them, you know how much that matters at 2 a.m. Several reviewers specifically mention switching away from another brand because of loose stools and seeing improvement here.

Third is value at the bag size. Owners with two puppies, or with a medium breed puppy, repeatedly note that the 26 lb bag lasts long enough to justify the price. A few mention that per-pound it beats what they were paying for smaller bags of comparable food. That tracks with the math above.

Now the complaints, and there are real ones. A common concern is that buyers didn’t read the label carefully enough. This is a small and medium breed puppy food — not for adult dogs, not for large-breed puppies (whose calcium and phosphorus needs are genuinely different, and getting that wrong during growth is not a minor issue), and obviously not for cats or other pets. I saw more than one review from someone who bought it for a Lab or a Great Dane puppy and then complained. That’s a reading problem, not a product problem — but it’s worth flagging because the listing title doesn’t shout it.

The second real complaint is staleness. The oils that make kibble smell appealing to dogs oxidize once air hits them, and a 26 lb bag left rolled up in a warm pantry will go rancid before it’s empty. A handful of reviewers mention their puppy losing interest near the bottom of the bag. That’s very likely a storage issue — but it’s a genuine downside of buying this size. My advice: decant into an airtight container, keep it cool, and don’t leave it in the original bag with the top folded over.

The third is allergies and sensitivities. Some puppies just don’t do well on a given protein source. If your puppy has already shown itching, ear issues, or digestive trouble on a similar formula, don’t buy 26 pounds of it. Start with a smaller bag from a different line, or read our guide to limited-ingredient and hypoallergenic puppy foods before committing.

One more thing I noticed: the negative reviews are almost entirely about fit, price, or storage — not about the food failing at what it’s designed to do. That’s a good sign. A 4.7 across nearly a thousand reviews usually means the product itself is solid and the one-star reviews are mostly misfires.

Pros From Real Users

• Puppies eat it enthusiastically, including notoriously picky small breeds and toy mixes.
• Owners frequently report firmer stools and fewer digestive surprises after transitioning.
• The 26 lb bag brings the per-pound cost down meaningfully for multi-puppy or medium breed homes.
• Kibble size is genuinely appropriate for small mouths, which isn’t a given at this price point.
• Coat and energy levels come up often in longer-term reviews as staying good through the growth phase.

Cons From Real Users

• It’s puppy-only — feeding it to an adult dog means paying puppy prices for the wrong nutrition.
• Not appropriate for large or giant breed puppies, whose mineral needs differ significantly.
• Won’t work for puppies with allergies or sensitivities to the formula’s protein sources.
• A 26 lb bag goes stale if you don’t store it properly, and some owners report exactly that.
• The upfront $68.25 stings if you’re used to buying 5 lb or 15 lb bags.

Who It’s For

This food fits best in a household with one or two small or medium breed puppies, or a breeder or foster who’s feeding a rotating group. It’s also a good pick for someone who’s already tried a couple of puppy foods and dealt with either refusal or loose stools — that’s the exact scenario where this tends to show up and, going by the reviews, tends to work.

It’s a poor fit for large breed puppy owners, single-toy-breed owners without airtight storage, and anyone whose puppy is already showing signs of a food sensitivity.

Final Verdict

NutriSource Small & Medium Breed Puppy isn’t flashy. It doesn

How We Evaluated This Product

We based this evaluation on the manufacturer’s published nutritional data, AAFCO compliance for growth-stage puppies, and a close read of more than 200 owner reviews across major retailers and pet forums. Our priority criteria were ingredient quality and protein sourcing, kibble size and texture for small-to-medium mouths, digestibility and stool consistency, and overall cost per day at the 26 lb bag price. We also weighed how consistently the formula performed across different breeds and appetites, since puppy food lives or dies by whether picky eaters actually finish the bowl.

Frequently Asked Questions

Q: Is NutriSource Small & Medium Breed Puppy worth the price compared to cheaper puppy foods?

At around $68 for a 26 lb bag, this sits in the mid-to-premium range rather than the budget tier. What you’re paying for is a meat-first recipe with named protein sources, added probiotics and taurine, and a kibble sized specifically for smaller mouths, which many budget foods don’t offer. If your puppy has a sensitive stomach or you want to avoid low-quality fillers, the per-day cost is reasonable for what’s in the bag. If you’re feeding a large litter or a very tight budget, a cheaper formula may work fine, but you’ll likely trade some ingredient quality.

Q: What size puppy is this food actually suited for?

Despite the name, this formula works well for puppies expected to land anywhere from roughly 10 to 50 pounds as adults, which covers most small and medium breeds like Beagles, Cocker Spaniels, French Bulldogs, and Shetland Sheepdogs. The kibble is small enough for tiny mouths but not so tiny that medium puppies inhale it. For toy breeds under about 10 pounds or giant breeds headed past 70 pounds, a breed-specific formula is usually a better fit.

Q: How should I store and handle the 26 lb bag to keep it fresh?

The 26 lb size is convenient but takes a while to finish for a single small puppy, so storage matters. Keep the kibble in the original bag, squeeze out excess air, and place the whole bag inside an airtight container rather than dumping it loose, since the bag’s lining helps preserve freshness. Store it somewhere cool and dry, and aim to use it within about six weeks of opening for best palatability. Wash your scoop and container between refills to avoid oil buildup and stale odors.

Q: Are there common allergens or safety concerns I should watch for?

The main proteins here are chicken and fish, so puppies with known chicken sensitivities should look elsewhere. It does contain grains, so it’s not suitable for a grain-free diet, though grains aren’t inherently an allergy risk for most dogs. As with any new food, transition over seven to ten days to avoid digestive upset, and watch for itching, ear infections, or loose stools that could signal an intolerance. This formula meets AAFCO nutrient profiles for growth, so the base safety profile is solid.

Q: How does this compare to other small-breed puppy formulas like Blue Buffalo or Purina Pro Plan?

NutriSource generally lands between budget options and the most premium boutique brands. Compared to Purina Pro Plan, it offers similar protein levels but leans on a slightly different ingredient philosophy with no corn, wheat, or soy, which some owners prefer. Compared to Blue Buffalo’s small breed puppy formula, NutriSource tends to be a bit more expensive per pound but is often praised for firmer stools and better acceptance by picky eaters. If your priority is proven feeding trials and lower cost, Pro Plan is a strong alternative; if you want a meat-forward recipe with probiotics and a smaller kibble, NutriSource holds its own.
