Ask five dog owners about multivitamins and you'll get five different opinions — some convinced they're essential, others sure they're a waste of money. Most of that disagreement comes down to a handful of persistent myths. Here's a closer look at each one.
"My dog's food already has everything they need."
What's actually trueCommercial dog food is formulated to meet AAFCO's minimum nutritional standards — a baseline, not necessarily an optimum. Processing, storage time, and your dog's individual age, breed, and activity level all affect how much of that nutrition actually gets absorbed. Meeting the minimum on a label isn't the same as your dog absorbing everything they need day to day.
"Multivitamins are just marketing — they don't actually do anything."
What's actually trueThe ingredients themselves aren't invented marketing claims — B-complex vitamins, biotin, zinc, and antioxidants have well-documented roles in canine energy metabolism, coat health, and immune function. The real variable is quality and consistency: a poorly formulated or inconsistently-used supplement won't do much. A well-formulated one, given daily, is a different story.
"I can just give my dog a human multivitamin."
What's actually trueThis one matters for safety, not just effectiveness. Dosages and safe nutrient ranges differ between species, and some common human supplement ingredients — like xylitol in gummy vitamins — are toxic to dogs. If you're supplementing, it needs to be formulated and dosed for dogs specifically.
"Only old or sick dogs need supplements."
What's actually trueNutrition gaps aren't reserved for senior or unwell dogs — highly active dogs burn through nutrients faster, picky eaters may not get consistent nutrition from meals, and even healthy adult dogs can benefit from proactive daily support rather than waiting for a problem to show up.
"All dog multivitamins are basically the same."
What's actually trueFormulation, ingredient sourcing, and the form of the product all vary a lot — and the best supplement in the world doesn't help if your dog won't eat it. That's the thinking behind PetVita Multivitamin Chews: a vet-inspired formula in a soft chew dogs actually want, with no artificial colors or unnecessary fillers.

Common Questions
Do I need a vet's approval before starting one?
It's always a good idea to check with your vet first, especially if your dog has an existing condition or takes medication.
How long until I might notice a difference?
Every dog is different. Some pet parents report noticing changes in energy and coat within a few weeks of consistent daily use.
