Pet parents want “real benefits,” not vague promises. But functional claims can backfire fast when results feel slow, unclear, or overstated.
Skin & coat and joint health tend to convert well because the need feels concrete, especially for dogs. Probiotics also sell, but they trigger skepticism when brands skip strain/CFU details, overpromise outcomes, or blur the line between “supports” and “treats.”

In practice, “skepticism” is not one problem. It is a mix of priority gaps (what owners say matters vs what they buy), evidence gaps (what is claimed vs what is shown), and expectation gaps (what owners expect to see vs what biology can deliver). This article uses published consumer data and veterinary literature to separate what drives purchase from what triggers doubt.
Which functional benefits actually drive purchase in pet food—and how do dog vs cat priorities differ?
Many brands treat “functional” as one checkbox. Pet parents do not. They rank needs, and dogs and cats do not rank the same.
Dog owners most often select skin & coat and joint health as top health-related purchase drivers, while cat owners are more likely to choose “none of the above,” with digestion and urinary/kidney concerns appearing more often when they do choose a benefit.
Why this matters for claims strategy
When a benefit matches a clear, common “need state,” it feels easier to justify at the shelf. When it does not, the claim must work harder to earn belief. This is why broad “daily wellness” claims often need stronger proof cues, while skin & coat can rely more on perceived visibility. It also explains why cat claims can feel harder: more buyers do not shop by function, and the top needs are narrower. If a brand ignores this split, the same front-of-pack claim can convert for dogs and do almost nothing for cats.

Why probiotics sell (digestive visibility) but also trigger skepticism (strain/CFU/viability gaps)?
“Gut health” is easy to understand. That makes probiotics attractive. It also makes exaggeration easy, which is why this category attracts pushback.
Probiotic claims drive purchase when they connect to observable outcomes like digestion regularity, stool quality, or sensitivity management. Skepticism rises when labels omit strain identity, CFU targets, or how viability is protected through shelf life.
What buyers silently expect to see
In veterinary and scientific reviews, probiotic effects are discussed as strain-specific and outcome-specific, with uneven evidence across endpoints and species. That means a claim like “supports immunity” can be technically possible but hard to prove in a way that feels concrete at the shelf. When brands avoid specifics, consumers often interpret that as “marketing.” On the other hand, when a label states the strain(s), intended benefit, a CFU level at end of shelf life, and simple storage guidance, it reads like a controlled product rather than a slogan. This is not only a science issue. It is a trust issue.

Why joint claims convert for aging pets—and where “mobility” claims start to feel like hype?
Joint support is a high-intent need state. But it is also where brands often overpromise, and where results are hardest for owners to attribute to one product.
Joint and mobility claims convert because owners fear decline and pain. Skepticism appears when claims imply treatment, or when ingredient lists lack dose clarity and realistic time windows.
The evidence is mixed, so the wording must be disciplined
In the veterinary literature, common joint nutraceuticals show mixed or inconclusive results across studies. That does not mean “no one benefits.” It means the average buyer should not be promised guaranteed outcomes. For trust, joint claims should avoid disease language and focus on “supports mobility” with a defined evaluation window (for example, weeks, not days), plus the main confounders owners should control: weight management, activity pattern, and baseline diet consistency. When labels do not do this, the most common consumer story becomes: “I tried it and nothing changed,” which quickly turns into skepticism about all functional claims. A claim can be compliant and still feel untrustworthy if it sets the wrong expectation.
| Joint claim risk |
What to do instead |
| Implying arthritis treatment |
Use structure/function language: “supports mobility” |
| Ingredient name only |
Provide standardization or dose transparency where possible |
| “Fast results” expectation |
State realistic evaluation windows and key confounders |

Why skin & coat claims feel more believable—and what evidence people implicitly expect (omega specifics)?
Skin and coat benefits look “visible,” so they feel believable. But visibility also raises expectations, and poor specificity can still trigger doubt.
Skin & coat claims convert well when they are tied to omega sources and realistic timelines. Skepticism grows when “Omega-3” is treated like a magic word without source, dose context, or rancidity control.
Omega is not one thing
In veterinary discussions of fatty acids, the “what” matters: EPA/DHA from marine sources behave differently than ALA from plant sources, and product freshness matters because oxidized oils can undermine both palatability and perceived benefit. This is where skepticism becomes practical. If a label does not explain the omega source, owners may assume it is a token add. If packaging does not protect oils from oxygen, light, and heat, owners may experience odor changes or reduced acceptance and conclude the benefit was fake. A skin & coat claim is therefore not only a formulation decision. It is also a stability decision. Brands that align the claim with source clarity and oxidation control signals tend to earn more belief.

What trust signals reduce skepticism: evidence style, wording boundaries, and credible sources?
Skepticism is often caused by missing signals, not by the claim topic itself. People buy when they feel the brand is measurable and honest.
Trust increases when packaging uses compliant “supports/helps maintain” language, shows specific proof cues (ingredient identity, dosing logic, stability logic), and points to credible validation pathways without promising cures.
A practical “claim credibility” checklist for packaging and landing pages
To reduce skepticism, separate three layers: (1) the benefit statement, (2) the proof signal, and (3) the expectation boundary. The benefit statement should stay in structure/function territory, not disease territory. The proof signal should be specific enough to look verifiable (for probiotics: strain + CFU logic; for joint: ingredient standardization or clear rationale; for skin: omega source and stability control). The expectation boundary should tell the buyer what success looks like and when to evaluate it. This is also where packaging matters: if the product is sensitive to moisture, oxygen, or heat, the pack must protect it, and the messaging must match that reality. As a flexible packaging manufacturer, we focus on barrier design, seal integrity, and route-stress durability so your product performance does not contradict your front-of-pack claims.

FAQ
- Which pet food functional claim converts best?
In many dog-food purchase-driver datasets, skin & coat and joint health are among the most selected health benefits, but performance depends on species and need state.
- Why do probiotic claims get questioned more often?
Because outcomes feel broad, and many labels omit strain identity, CFU logic, and viability protection details, which makes the claim feel less verifiable.
- How can brands avoid “medical claim” risk while still being persuasive?
Use structure/function language (supports/helps maintain), describe normal function outcomes, and avoid “treat/cure/prevent” phrasing.
- Do omega-3 claims need more detail than “contains Omega-3”?
Yes. Source clarity and stability signals matter because oxidation and weak specificity can undermine trust and perceived results.
- How does packaging affect functional claim credibility?
If the pack fails to protect sensitive actives (moisture, oxygen, heat), consumer experience can contradict the claim, which increases skepticism and returns.
