A useful dog food review does three things. It tells you whether the reviewer fed the food to a real dog, it discloses any free product or affiliate link, and it ideally covers more than one animal.
Do affiliate links mean a review can't be trusted?
Not on their own. An affiliate link means the site earns a small commission if you buy through it, and plenty of honest reviewers use them to cover the cost of running a site.
The link itself tells you nothing about honesty. What matters is whether the reviewer discloses it, and whether the same product would have made the list without it. A site that's upfront about affiliate links, and still tells you when a food isn't great, is doing the job properly. Little Green Dog runs an affiliate programme too, and reviewers who cover our kibble are free to use it.
Did the reviewer actually feed the food to a dog?
This is the biggest single tell, and it's the easiest one to miss. A lot of "reviews" are built from the ingredient list and the guaranteed analysis on the bag, with no dog involved at all.
Look for specifics that only come from feeding it. How the dog's stool changed, whether they ate it eagerly or picked at it, how long the bag lasted, whether the coat or energy shifted over weeks rather than days. A review that only repeats what's printed on the packaging is a summary. You can write one of those without ever opening the bag.
How many dogs did the review cover?
One dog's reaction to a food is one data point, not a verdict. A dog that does brilliantly on a food might be an easy case, and a dog that reacts badly might have an unrelated issue. Neither tells you much about your own dog.
The more useful reviews either test across several dogs, or are honest that it's a single-dog account and frame it that way. Watch for a review that generalises from one dog to a sweeping claim about the whole brand. That's a bigger call than the evidence supports.
Does the review say if the food was given for free?
It should. A reviewer who received a free sample and says so upfront lets you judge whether that changed the outcome. Where there's no disclosure at all, you can't tell either way.
Little Green Dog sends free samples to reviewers who want to try the kibble, the same way most brands do. Any reviewer covering our food is welcome to say so.
What are review-farm sites, and how do I spot one?
A review-farm site publishes ranked "best dog food" lists for dozens of brands. The write-ups are near-identical, the photos are stock, and there's no sign a dog ever ate any of it. The giveaway is the writing itself. Every entry is the same length, hits the same three adjectives, and never names a dog or a result.
Check the site for an "about" page with a real person and a real dog. Then check the publish date. A "2026 guide" written in 2022 and never updated is worth less than it looks.
How do I read customer reviews differently from editorial reviews?
Customer reviews are useful for pattern-spotting but weak on individual judgement. One glowing review means little. Fifty that all mention the same thing, a dog's itching easing off or a fussy eater finally eating, are harder to fake. The named ones beat the anonymous ones: a review giving the dog, the problem, and how long the change took is a claim someone has put their name to. "Great product, five stars" is not.
Editorial reviews carry more weight each, because the reviewer has more dogs and more foods behind them to compare against. The trade-off is that their own dog's tolerance still shapes the result. Read customer reviews for volume and an editorial review for depth.
What should I actually look for on a food, beyond the reviews?
Reviews are one input. The bag itself tells you more, if you know where to look. We've written a full checklist for reading a bag in order if you'd rather check a food yourself than rely on someone else's write-up.
If you're weighing up which food suits your own dog, that's covered separately in our guide to choosing the best dog food in NZ.
Our own kibble uses a single hydrolysed chicken protein, broken down so small most sensitive dogs stop reacting to it. It's grain-free and free from beef, dairy, gluten, wheat, fillers, and artificial colours. It's vet-formulated with 6+ functional superfoods, and every batch is checked by an independent laboratory across 73 factors. You can try it with a $19.99 2kg sample, backed by our 30-day Sensitivity Promise, before committing to a full bag.
Questions people ask
Are dog food review sites in NZ paid to rank certain brands?
Some are. Affiliate commissions and free samples are common and not inherently dishonest, but a site should disclose both. If a site won't say how it makes money or whether it received free product, treat the ranking with caution.
Does Little Green Dog pay reviewers or review sites for coverage?
We send free samples to reviewers who want to try the kibble and run an affiliate programme that reviewers can use if they choose to. We don't pay for a specific ranking or placement.
What's the fastest way to check if a review is genuine?
Look for a specific dog, a specific result, and a disclosure of any free product or affiliate link. If a review has all three, it's worth reading properly. If it has none, treat the rating as marketing.
