FAQ — Frequently Asked Questions

Lull is a soft plush companion with a removable module that plays a gentle, steady heartbeat and gives off a little warmth. For a dog — especially a puppy — that rhythm echoes the mother and littermates they used to sleep against, so a crate or a quiet room feels less alone. It's a comfort aid, not a medical device.

Yes. No pills, no sprays, nothing your dog swallows or absorbs — just a heartbeat and gentle warmth. For dogs with severe or ongoing anxiety, your veterinarian should always be your first call.

A small heartbeat module sits in a zippered belly pocket and pulses a slow, steady rhythm. It runs on 2 × AAA batteries (not included), so there's nothing to recharge and no throwaway electronics — just replace the batteries when they run low.

Yes. Slip the module out through the zip and the whole plush is machine-washable. Let it air-dry, pop the module back in, and it's ready for the next night.

About 35 cm of soft, breathable plush over PP-cotton fill — sized to hold, nuzzle and sleep against. In the box: one Lull plush companion and one removable heartbeat module.

Every dog is different. Many settle within a night or two once the heartbeat becomes familiar; some take a little longer. Keep it in the same spot — crate or bed — for a few nights so it becomes part of the routine.

First nights in a new home, rescues and adoptions settling in, crate training, fireworks and storms, vet visits and travel, and dogs who struggle with alone-time by day. Lull is a comfort companion, not a treatment for medical conditions.
