For current Plentum customers

Microbiome Care isn't changing.
We've added four new formulas

If your dog is on Microbiome Care, keep going. The four new formulas are for dogs who need extra help with one thing, like digestion or itching.

You don't need to add one. If you do, start with what you notice most.

Why a Plentum sachet

  • Sized to your dog

    Your dog takes 1 to 4 sachets a day, depending on the formula and their weight.

  • A powder

    There are no binders, because there's no chew to hold together.

  • Five formulas

    It's our daily formula, plus four targeted ones.

  • What it costs a day

    From $1.17 a day

    That's the price for a small dog. Add their weight and we'll show yours.

You know your dog best

You're usually the first to notice when your dog skips breakfast or scratches more than usual. A daily sachet is an easy way to support them, and it goes on the food they already eat.

  • Format It's a powder in a 2 g sachet that you pour over their food.
  • Binders Powder doesn't need binders to hold its shape.
  • Dose Every sachet holds a measured 2 g dose, with nothing to chew through.
  • Measuring Your dog takes 1 to 4 pre-measured sachets a day, by weight.
  • Mealtime Pour it over their food. A splash of warm water makes a light gravy.
  • Freshness Single-serve sachets stay sealed until you tear one.

Questions dog parents ask

What makes Plentum different from other pet supplements?

Most supplements are chews, and chews need binders to hold their shape. Ours is a powder, so it doesn't need a binder at all.

How do I give it to my dog?

Pour the pre-measured sachet (or sachets, for bigger dogs) over their food once a day. A splash of warm water makes a light gravy.

How soon will I see results?

Give it 4 to 12 weeks of daily use. Snap a photo and jot a few notes in week zero so you have something to compare against. Every dog is different, and results vary.

Can I give it to a dog with a sensitive stomach?

Ease it in gradually, starting with the sachet count for your dog's weight. If your dog takes medication or has a diagnosed condition, check with your vet first.

Will my picky eater actually eat it?

Many dogs eat it right over their food. If yours is fussy, a splash of warm water makes a light gravy.

What are the main ingredients?

It depends on the formula. Microbiome Care pairs a postbiotic with prebiotic fiber, and each targeted formula adds ingredients for its area. Tap a formula to see its full list.
