What Chewy, PetSmart, and Amazon Are Actually Looking for in Pet Product Claims

Most pet brands assume retailers are evaluating products - and they are. They're looking at ingredients, quality, category fit, pricing, consumer demand, packaging, reviews, and whether the product fills a gap in the market.

But that's only part of the picture - retailers are also evaluating risk.
That becomes very obvious when a product sails through formulation, branding, and marketing development, only to get stalled because of a few sentences on a package, website, or Amazon listing.

I've seen founders spend months perfecting a product, only to get stuck debating whether a claim should say "supports healthy joints" or "helps dogs with arthritis." To the brand, those statements may feel similar. To a retailer, they are very different.
​
Understanding that difference can save a lot of frustration, revisions, and delayed launches.

Preparing product listings, packaging, or retailer submissions? This is usually the stage where claim problems are easiest and least expensive to fix. I help pet brands identify issues before retailers do. Start with a claims review.

Retailers Are Looking at More Than Marketing

When a retailer reviews your product, they're asking this question:
Could this create a regulatory, legal, or marketplace problem for us?

That's the lens many brands miss.
Retailers have no interest in becoming part of a regulatory dispute. They don't want products making unsupported disease claims. They don't want customers filing complaints because marketing promises don't match reality. They don't want listings flagged, challenged, or removed.
From their perspective, every claim creates a certain amount of risk.
The stronger the claim, the greater the scrutiny tends to become.
That doesn't mean retailers want boring marketing.
​It means they want marketing that can be defended.

Disease Claims Are Still the Fastest Way to Create Problems

The biggest issues often start with disease claims.
These are claims that suggest a product diagnoses, treats, mitigates, prevents, or cures disease.
Examples include language such as:

• Treats arthritis
• Prevents urinary tract infections
• Eliminates allergies
• Reverses cognitive decline
• Reduces anxiety disorders
• Heals skin disease

Disease claims place products into a very different regulatory conversation. Once marketing starts sounding like medicine, reviewers naturally begin asking questions about evidence, intended use, regulatory status, and substantiation.

Most pet supplement and wellness brands are not trying to enter that conversation.

That's why structure/function claims are often safer and more appropriate.
"Supports healthy joint function" communicates something very different than "treats arthritis," even though both statements may be attempting to describe a similar customer benefit.

Small wording choices creates very different levels of risk.

Retailers Also Evaluate Implied Claims

Here's where things become a little more complicated.

Many brands know enough to avoid obvious disease claims, but they overlook implied claims. An implied claim doesn't directly say a product treats a disease. Instead, it strongly suggests it.

For example:
"My dog's arthritis disappeared."
"Our cat no longer needs medication."
"A natural alternative to prescription treatment."

Statements like these frequently appear in testimonials, reviews, graphics, videos, social media posts, Amazon A+ content, and website copy. The problem is that reviewers often evaluate the overall message, not just the technical wording.

A compliant product description sitting next to a risky testimonial can still create concerns.

I've seen brands carefully edit their package claims while completely overlooking the customer stories displayed three inches away.

Burn this into your brain: retailers look at the entire consumer experience, not just a single sentence.

Evidence Matters More Than Industry Habit

One of the most common misconceptions in pet marketing is the idea that a claim is acceptable because everyone else is using it, but that's not actually how it works. 

A claim doesn't become stronger because it's popular. It becomes stronger because it can be supported.

Retailers increasingly want confidence that brands can substantiate what they're saying. If a claim is challenged, can the company explain where it came from? Is there research supporting it? Can the brand provide a reasonable basis for the statement?

The more specific a claim becomes, the more important those questions become.

For example, "supports normal immune function" generally carries a different evidentiary burden than "improves immune response by 63%."
One is broad support language. The other is a measurable performance claim. That difference matters a LOT to regulatory bodies and retail platforms. ​​

Many retailer review problems aren't caused by the product. They're caused by the way the product is positioned. Brands hire me to pressure-test claims before launch, not after a listing gets flagged. Learn more about claims review.

Amazon Adds Another Layer

Amazon introduces challenges that many brands don't anticipate. Founders often imagine a reviewer reading every word of a listing from beginning to end, but usually automated systems identify issues first.

Amazon uses systems designed to detect language that may create compliance concerns. Disease references, treatment language, risky terminology, and unsupported health claims can attract attention before a customer ever sees the listing.

What makes this frustrating is that the triggering language is not always obvious.

Sometimes it's a phrase in an image. Sometimes it's a testimonial. Sometimes it's buried in A+ content that nobody has reviewed in months.
​
If you've ever spent a Tuesday afternoon trying to figure out why a listing was flagged, you know exactly what I'm talking about.

Consistency Matters More Than Most Brands Realize

At the end of the day, platforms look at the entire consumer takeaway. The problem occurs when:
​

• Marketing says one thing.
  
• Packaging says something slightly different.
  
• The website introduces new language.
  
• Amazon content adds additional benefits.
  
• Customer testimonials push the claims even further.

Individually, each piece may seem harmless. Collectively, they create confusion about what the product is actually intended to do.

Retailers want a clear and consistent story. But when every touchpoint describes the product differently, risk increases because reviewers have a harder time understanding the intended positioning.

Consistency in your marketing copy makes it more credible, and less likely to be flagged or delisted.

The Brands That Move Through Review More Smoothly

No review process is perfect, and no retailer applies standards exactly the same way. Still, the brands that tend to encounter fewer problems usually share a few characteristics.

They understand the difference between structure/function and disease claims. They maintain substantiation for important claims. They review testimonials before publishing them. They align packaging, website content, retailer listings, and sales materials around the same core messaging.

Most importantly, they build compliance and veterinary review into the content development process instead of treating it as a final review step. That shift alone can prevent a remarkable number of problems.

​Compliance Isn't Just About Avoiding Trouble

Many brands think claim compliance is simply about staying out of trouble, and sure, that's part of it.
But there's another benefit that often gets overlooked.
Good claim strategy builds trust.

Retail buyers are paying attention. Pet parents are paying attention. Veterinary professionals are paying attention.
​
When claims are clear, supportable, and appropriately framed, they create confidence. Customers understand what the product is designed to do. Retailers understand how it should be positioned. Brands spend less time defending their marketing and more time growing their business.
Overstated claims may generate attention in the short term, but credibility tends to create better long-term outcomes.

​The Bottom Line

Chewy, PetSmart, Amazon, and other retail channels are not simply evaluating products. They're evaluating the risk associated with the claims surrounding those products. That means reviewers are paying attention to disease claims, implied claims, testimonials, substantiation, consistency, and overall product positioning. The brands that navigate retail review most successfully are rarely the ones making the biggest promises. They're usually the ones making the clearest promises. When you understand what your product does, what evidence supports it, and how to communicate those benefits responsibly, retailer review becomes much less painful.
​
And that's usually a better use of your time than spending a Tuesday afternoon trying to figure out which sentence got your listing flagged.

Retailer policies are only one piece of the puzzle. My Complete Guide to Pet Supplement Claims explains how retailer standards fit alongside FDA considerations, veterinary review, and evidence-based marketing.
