Sarah M. ✓ Verified Buyer

“Got our golden retriever at 8 weeks … cried nonstop for the first 2 nights… ordered not really expecting much but by the end of the week she was settling within about 10 minutes. Even my husband admits it’s doing something now.”

Chris D. ✓ Verified Buyer

“Thought our border collie would just settle on his own. Two weeks after cubby and things are genuinely better. I just wish id started it from day one instead of waiting for it to “sort itself out””

Priya K. ✓ Verified Buyer

“Within a few days the howling dropped off enough that even our neighbour said something unprompted. Absolute lifesaver if you want to calm your pup.”

Rachel & Steve ✓ Verified Buyer

“We have raised two dogs before with no problems. Our kelpie pup needed a little bit of help. Started calming down straight away and now at three weeks shes behaving better than ever. Sometimes you just get a puppy who needs a bit more help and thats fine”

Liv ✓ Verified Buyer

“Bought my sister one when she got a puppy. Texted me after about a week saying her pup was sleeping through the night already. It’s one of those things where you don’t realize how much its helping until you think about how bad the first few nights were compared to now.”

What to expect, and when

  1. The signal starts the moment you plug it in
    Day 1

    The signal starts the moment you plug it in

    No activation, no waiting period. The same scent signal your puppy's mother produced starts working in the background from the first night home.

  2. The adjustment window
    Day 7

    The adjustment window

    This is usually the stretch where the crying at the door, the crate resistance, and the 3am pacing start to ease.

  3. The new normal
    Day 30+

    The new normal

    By now it's routine, not a novelty - for your puppy and for you. Subscribe & Save keeps the signal running through the rest of the early-development period. The goal was never a puppy "fixed" overnight - it's one you raised through the hard part properly.

The mechanism

The signal was always real. It just stopped early.

In 1999, a veterinary researcher identified the exact compound a mother dog produces for her puppies in the days after birth. Not a drug. Not a fragrance. A scent signal her puppies are already wired to read as safe.

Cubby releases a lab-identified replica of that same signal, continuously, so the move home doesn't come with an abrupt stop to something your puppy already trusted.

It isn't ours and we don't claim it is. It was identified by researchers, it's used across the category, and it works because it's biology your puppy already knows — not because of anything we invented.

Not a sedative. Not a masking scent.
The same signal, kept going.

Common questions

Will this actually work for my dog?

We won't promise a universal fix — no calming product works identically for every dog. What we can say is this continues a real biological signal your puppy already trusts, not a new intervention. If it's not a fit, the 30-day guarantee means you're not stuck with it.

Is this just another subscription trap?

No. Subscribing is opt-in, not required to purchase, and you can pause or cancel any time. We'd rather you cancel cleanly than get a support ticket about a charge you didn't expect.

Is this safe for a puppy this young?

Yes — checked against the manufacturer's own spec specifically for young animals, not just a general "safe for dogs" label.

I already tried a calming chew / ThunderShirt / camera app — why would this be different?

Different mechanism. Chews are ingested and can carry dosing or drowsiness side effects; a wrap manages the symptom, not the cause; a camera app manages your anxiety, not your puppy's. This is a passive scent signal — nothing to dose, nothing to wear that restrains them, nothing to watch.

Isn't this a waste of money?

The diffuser + refill starts at $49.99 — less than most calming-chew subscriptions over the same period, with no ongoing dosing cost baked in. Backed by a 30-day money-back guarantee either way.

My puppy is still really young — should I just wait and see?

Early intervention is what prevents this period from calcifying into adult temperament — waiting isn't the safer default, starting early is.

Will this make my puppy drowsy or sedated?

No — this isn't a sedative and there's nothing your puppy ingests. It's a scent signal they're already wired to recognise, not a drug with a dosing or drowsiness risk like some calming chews carry.

How long does one kit actually last?

Your kit ships with the diffuser and two refill bottles — about 30 days of continuous coverage. Subscribe & Save times the next shipment to that, so you never run out mid-transition.
