Is a food labelled vet tested automatically better?
Not necessarily. Vet tested has no standardised definition and can cover very different realities, from a one-off opinion to a rigorous feeding trial (WSAVA, 2021). What matters is the nature of the test: protocol, duration, independence, not the mere word vet.
General documentary information. For an individual animal, a veterinarian's advice takes precedence over any online content.
A vague phrase with no specification
Tested or approved by veterinarians is not a regulated claim; it states neither the protocol, nor the number of animals, nor the duration (FDA, 2024). It is a world away from a feeding trial run to AAFCO or FEDIAF protocols, which follows real animals over a set period. The concrete benchmark: an AAFCO adult maintenance trial requires at least 8 animals fed the food exclusively for 26 weeks, of which at least 6 must finish with no sign of deficiency or excess (AAFCO, 2024). A marketing phrase, by contrast, may reflect no protocol whatsoever.
What makes a test convincing
An informative test states its method and its independence. The WSAVA advises checking whether a brand employs a qualified nutritionist and publishes its research, rather than trusting the word vet (WSAVA, 2021). A test run or funded by the brand should be read with that in mind. Quality is judged on documented rigour, not on the endorsement printed on the front of the pack.
| Type of "test" | Reach | What to verify |
|---|---|---|
| Marketing phrase | Low | Protocol unstated |
| One-off vet opinion | Limited | Independence |
| Feeding trial (AAFCO, FEDIAF) | High | Duration, numbers, results |
Petipedia separates veterinary endorsement claims from documented feeding trials, to weigh what a test actually proves.
