What it does

The bacteria and the fuel they need.

The bacteria, the fuel, and the enzymes

Probiotics without prebiotics is hiring staff and skipping payroll. This scoop ships the 5-strain blend, the prebiotic fiber that feeds it, and a 7-enzyme digestive blend to help break the meal down.

A calmer, boring gut

Boring is the goal: formed stools, steady appetite, less drama after diet changes, boarding, or antibiotics.

Immune support starts in the gut

A large share of immune activity happens in the digestive tract — supporting one supports the other.

What to expect

The honest timeline.

Days 3–7

The changeover

The gut population starts shifting. Some dogs get briefly gassier — that's the changeover, not a problem.

Weeks 2–4

What owners notice

Steadier stools and fewer sensitive-stomach episodes.

Ongoing

Balance through everything

Daily use keeps the balance through diet changes, stress, and seasons.

And we back every one of those 90 days.

If you don't see a difference by then, we'll refund you — no return needed.
