      It ended the nightly pacing by week 3. He settles on his bed now instead of circling the room until 2am.

      Non-sedative is the whole point. He is still goofy and himself, just not wound up over every noise outside.

      Our rescue used to melt down on walks. 4 weeks in and she can pass another dog without losing it.

      Storms used to mean a shaking dog under the bed for hours. Last one she stayed on the couch with me.

      You got questions, we got answers

      Find answers to the questions dog owners ask us most.

      No. CalmAxis is non-sedative. It works on the gut-brain axis rather than knocking your dog out, so their personality, energy and appetite stay exactly the same. They are just calmer underneath it.

      Most owners notice easier evenings inside the first week. Give it a full 21 days of daily chews for the complete effect, since the postbiotic complex needs time to rebuild the gut lining.

      2 chews a day for every size. Up to 25 lbs, 26 to 75 lbs, and over 75 lbs all get the same simple daily dose, so there is no weight math and no guessing.

      CalmAxis is a daily supplement, not a drug, and many owners use it alongside or while tapering off a prescription. Check with your vet before changing anything your dog is currently on.
