Lauren J.
Every single time someone came over she'd piddle on their shoes and I stopped inviting people because I was so embarrassed. I tried the whole ignore-her-for-ten-minutes-when-you-walk-in thing for months and it never stuck. My sister came over Sunday and there was nothing — no towel, no spray, nothing.

Bought this after watching my dog on the camera pacing at the door for like 40 min before he went on the rug. Broke my heart. Anyway. It's been about a month. Floors have been clean for 2 weeks straight now. He does not love the taste, I have to put it in wet food, but he takes it.

Put a camera up thinking I'd catch him doing it out of spite and instead watched him pace at the door for forty minutes. Found PetCalm Co. in a Reddit thread that night at 2am. Floors have been clean two weeks straight now, he does hate the taste though so it goes in wet food.

Crate made it worse, he'd just go in it and sit there. My sister in law swore by these so I caved. 5ish weeks and he's out of the crate during the day, I genuinely did not expect to be writing this.

Stop Indoor Peeing And Anxiety In Dogs With This Science-Driven Solution
Your dog isn't being bad. They're panicking — and the accidents are what panic looks like.
Cleaning the carpet doesn't touch that. Neither does a plug-in that only works in the room it's in.
PetCalm Co. Calming Drops work from the inside. They calm the stress response itself, so your dog settles instead of pacing, whining and circling by the door the moment you leave.
A few drops in their food each morning. That's it. They stay calm while you're at work — not just while they're standing near a diffuser.
Calm dog. Clean floors. No crate.

Trustpilot Reviews
Love this for my senior dog
Vet ruled out a UTI twice which somehow made it worse because that meant it was me. Someone in a dog Facebook group mentioned PetCalm at like 11pm when I was venting. Third bottle now. Still had one Tuesday so I won't say cured, but it's once a week instead of daily.
Huge Difference!
Put a camera up thinking I'd catch him doing it out of spite and instead watched him pace at the door for forty minutes. Floors have been clean two weeks straight now. Only reason it's not five stars is he clocks it if I don't put it in wet food.
Worth Every Penny
Crate made it worse, he'd just go in it and sit there, which was horrible to come home to. My sister in law swore by these so I caved. 5ish weeks and he's out of the crate during the day. Genuinely did not expect to be writing a review.
Finally Relief
He pees when my husband walks in but never me, and it's been a whole thing between us for a year — my husband thinks the dog hates him. Vet tech mentioned PetCalm offhand at a checkup and I wrote it on my hand. Hasn't happened since mid June.
Did you know indoor peeing affects 84% of dogs?
Thousands of dog owners trust PetCalm Co.
Just a few drops of PetCalm Co. Advanced L-Theanine mixed straight into food once a day is enough to reach what the cleaning, the crate and the extra walks never did.
The accidents aren't a training problem — they're a stress response. So the drops don't work on the behaviour. They work on the panic underneath it, calming your dog's stress response so they settle on their own instead of pacing, whining and circling the moment you leave the house.
Calm, not sedated. No zombie effect, no personality wiped out, no prescription. Same dog, just not a frightened one.
That's a dog who settles while you're gone, a floor that's clean when you get home, and no more crating them for eight hours to protect the carpet.
No fillers, no gums, no pill battle. Precision-dosed by bodyweight, straight into their dinner — they won't know it's there.

Frequently Asked Questions
How fast will I see a difference?
+
Most owners notice a change within the first 2–3 days — usually the pacing and whining settling before anything else. The accidents typically drop off from there as your dog stays calm through the days you're out.
Is this vet reviewed or 3rd party tested
+
Both. The formula is reviewed by a licensed veterinarian, and every batch is third-party tested by an independent US lab for purity, potency and contaminants. We don't just say what's in the bottle — we verify it.
Will my picky dog actually eat it?
+
Yes — the drops have a subtle chicken flavour and are odourless, so mixed into their normal food they won't even know it's there. It's exactly why we made this a potent liquid instead of a chew — there's nothing to sniff out, spit behind the couch, or refuse.
Why liquid instead of a chew or a tablet?
+
Because liquid is more potent and research shows its tolerated and absorbed better.
Some dogs HATE chews and because chews are one-size-fits-all and dogs aren't. Drops are dosed precisely to your dog's bodyweight, absorb faster than a chew or tablet, and disappear into their normal dinner — no sniffing it out, no spitting it behind the couch, no pill battle.
Can I give it with his heart or any other medication?
+
PetCalm Co. is generally safe to give alongside other medications — but if your dog is on heart medication, prescription anxiety medication, or any ongoing treatment, check with your vet f
Where is this made and sourced
+
Everything is sourced from USA farms and made in Colorado, in an FDA-registered facility. No imported ingredients, no overseas manufacturing, no mystery supply chain — grown here, made here, tested here.
Im not sure if my dog is anxious should I still give it?
+
Anxiety in dogs rarely looks like "anxiety" — it looks like pacing, key-jangling panic, circling by the door, and accidents that only happen when you're out. If your vet has ruled out a medical cause, stress is the most likely reason for the peeing — and it's exactly what the drops are made for.
