A routine for two dogs

Heath was concerned about taste because their dogs often refuse vitamins. This time, both dogs accepted the supplement readily. The positive response made it easier to keep the routine going, and giving it has become a regular part of their household’s daily care.

CELLULAR AGING RESEARCH

Curiosity starts at the cellular level.

Scientists are exploring how NAD+ pathways relate to aging in dogs. Protocol brings NMN and NAD+ together with resveratrol and CoQ10 in an everyday liquid formula.

2024 canine trial

A closer look at aging dogs.

Randomized, placebo-controlled study · Senior dogs

Researchers enrolled 70 dogs to study a separate senolytic and NAD+ precursor combination. Owner-assessed cognitive scores differed between groups at three months; measured activity and in-house cognitive testing did not show significant group differences.

The cited trial tested LY-D6/2, a different senolytic and NAD+ precursor combination—not Pawprint Protocol. It did not establish increased lifespan or results for this formula. Research context is not an individual outcome promise.

GOOD QUESTIONS.

Let’s make
it simple.

More clarity. A little less guesswork.

Talk to the Pawprint team ↗
How long does a bottle last?

Each bottle contains 60 mL. The bundle chooser shows estimated supply and the matching Recharge delivery interval for your selected dog size and bottle count. Follow the serving directions on your bottle and review the actual recurring plan before ordering.

When should I expect a change?

There is no guaranteed timetable. Follow the label, keep a consistent routine and discuss your observations with your veterinarian. A supplement complements everyday care.

When will my subscription refill?

The buy box shows the actual delivery interval for the available Protocol subscription. It is separate from the daily serving. Review the recurring price and interval before ordering; manage, pause or cancel through your account.

How does Protocol differ from Daily Wellness?

Protocol contains NMN, NAD+, resveratrol and CoQ10, with a focus on cellular energy and senior dog vitality. Wellness uses a different ingredient formula. Review the labels with your veterinarian to choose what fits your dog.

Can I combine it with medication or other supplements?

Ask your veterinarian to review the complete label before combining products or changing your dog’s existing care. Your dog’s history and individual needs matter.

What comes with a subscription?
