Simple daily care for dogs, one meal at a time

Our mission is to support your dog's everyday health with simple daily care.

Every supplement is sized to your dog, vet formulated, and backed by published research.

We picture that care fitting into the meal you already serve, for every dog.

Six steps behind every supplement

This is how each supplement goes from research to a sachet, and where you can check each step.

  • 35unique actives, each one explained
  • 5supplements, each with its own focus
  • 2 gper sachet, 1 to 4 a day by your dog's weight
  • 0binders in the sachet
  1. 01

    Research the actives

    We start with the ingredient and read what's been studied in dogs, and what hasn't, before anything goes near a supplement.

  2. 02

    Choose the dose

    Every active gets an amount we can explain from the research. If a study used more, we say so on the ingredient page.

  3. 03

    A binder-free 2 g sachet

    A powder needs no binder to hold its shape. Pour the pre-measured sachets for your dog's weight over the food they already eat, so you don't need a new bowl or a new food.

  4. 04

    Test every lot

    Every lot of all five supplements is lab-tested before it ships, and each one has a Certificate of Analysis.

  5. 05

    Say where the research stops

    For each active we say what the research shows and where it stops. The studies looked at the ingredients, not at Plentum's own supplements.

    Listen to dog parents

    Your questions shape what we explain and what we build next. We read every message.

We only sell what we'd give to our own dogs

Plentum started as a passion project for our own dogs.

What we stand behind, and where to check it

These are our promises, and how you can check each one.

  • Who made it, and how to reach us

    Every box says “Manufactured for Plentum Inc., New York, NY”. Microbiome Care is made in the USA, and our four newest supplements are made in Canada in an FDA-registered facility. Questions? Email hello@plentum.com.

  • Sized to your dog

    Dosing goes by weight, so a small terrier and a big shepherd each get the amount that fits them. Every supplement is vet formulated.

  • Every lot is lab-tested

    Every lot of all five supplements is lab-tested and has its own Certificate of Analysis. Lots of the four new supplements are tested for Salmonella, E. coli and more. See the results.

  • Your vet comes first

    If your dog has a health condition or takes medication, check in before starting anything new.

  • Careful wording

    A daily supplement supports normal function, so that's how we describe ours. We don't borrow other brands’ results.

What the research shows

We read the published research on every active. The studies are about ingredients, or about other products that contain them.

Our ingredient pages put each dose next to the research behind it. Each ingredient page shows the dose beside the study it comes from.

How we read the science →   The ingredient library →

We leave out chew binders and artificial flavors and colors. Each label lists the other ingredients.

Five supplements, each with its own focus

Start with a daily foundation, then add a focused supplement when one area needs extra attention. Every supplement uses the same routine: tear open a sachet and pour it over food.
