Walk into any pet shop in October and you will find a wall of calming products - diffusers, sprays, chews, tablets, collars and wraps. They are not interchangeable. They work in different ways, take different amounts of time to kick in, and suit different animals. This guide explains what each format actually does so you can pick the right one, and more importantly, start it early enough to work.
Most calming products need time to work!
Diffusers and daily supplements need about two weeks.
Sprays and tablets are the only genuine short-notice options.
What Calming Products Do - and Don't Do
The aim is to lower the intensity of your pet's stress response so they can settle themselves. A calming product does not switch fear off, and it is not a sedative. A pet on a calming supplement should still be alert, responsive and behaving like themselves - just less reactive to the thing that normally sets them off.
That distinction matters, because it sets expectations correctly. If you are hoping your dog will sleep through a firework display, no over-the-counter product will deliver that. If you are hoping they will shake less, settle faster and recover sooner, that is a realistic goal.
Calming products are not the answer to every problem. They help with fear and anxiety - noise, fireworks, travel, vet visits, visitors, being left alone, a house move or a new baby. They will not fix:
- Hyperactivity or over-excitement caused by too little exercise or stimulation
- Indoor toileting from incomplete house training or a medical problem
- Problem behaviour rooted in inconsistent training
- Aggression of any kind towards people or other animals
For any of those, speak to your vet or a qualified trainer or behaviourist. A diffuser will not substitute for the right advice, and aggression in particular needs professional input rather than a shop-bought product.
The Formats Explained
Pheromone diffusers
The strongest option for a pet that is anxious at home. They plug into a socket and release a synthetic copy of a pheromone the animal's own species produces naturally - the appeasing pheromone a mother dog gives her pups, or the facial pheromone a cat leaves when it rubs against furniture. The animal reads it as a signal that this space is safe.
Because they are species-specific, a dog product does nothing for a cat and vice versa. They are odourless to us and do not interfere with medication. The catch is lead time: allow around two weeks to build up in a room, and plug it in where your pet actually spends time rather than where it is convenient.
Calming sprays
The same active idea in a bottle you can apply directly to bedding, a blanket, a crate, a carrier or the back of the car. Sprays are the most flexible format and the best genuinely short-notice option - spray fifteen minutes before and let it dry rather than spraying onto a pet.
Daily supplements and chews
Given with food or as a treat, these work from the inside and build up over days. They suit pets who are generally anxious rather than only on one night, and they are the easiest format to keep going year-round. A chew has a practical edge over a tablet: no wrestling a pill into a nervous dog, and the treat itself becomes a positive moment.
Tablets and drops
Faster-acting than daily supplements and designed for a known event - a car journey, a vet appointment, a night of fireworks. Most want to be given a few hours before, not during. These are what you reach for when the forecast has changed and you need something today.
Calming collars
A wearable, slow-release version that travels with your pet rather than staying in one room. Useful for dogs that move between rooms or spend time away from home. Less powerful than a plugged-in diffuser in a closed room, but it goes where they go.
Pressure wraps
A snug garment that applies constant, gentle pressure to the chest and torso - the same principle as swaddling a baby. The response is genuinely variable: some dogs visibly relax within minutes, others are unmoved. Worth trying, not worth relying on alone. Fit matters, and introduce it on a calm day first so the wrap does not become a warning sign.
Which Format, How Fast, How Long
| Format | Start it | Lasts | Best for |
|---|---|---|---|
| Pheromone diffuser | 2 weeks ahead | About a month per refill | Ongoing anxiety at home, one main room |
| Calming spray | 15 minutes ahead | A few hours | Bedding, crates, carriers, the car, short notice |
| Daily supplement or chew | 1-2 weeks ahead | Continuous while given | Generally anxious pets, year-round support |
| Tablets and drops | A few hours ahead | Hours | A specific known event |
| Calming collar | A few days ahead | About a month | Pets that move around or travel |
| Pressure wrap | Minutes - but practise first | While worn | Dogs that respond to physical contact |
Our Calming Range
Clover+ Peaceful Pooch
Clover+ Peaceful Pooch is our own daily calming supplement, made as a soft treat rather than a tablet. That sounds like a small thing and it is not - getting a pill into an already anxious dog is its own small battle, and one that works against what you are trying to achieve. Most dogs take these straight from the hand.
How to use it: daily, starting about two weeks before you need the effect. It suits year-round use for dogs that are anxious about more than fireworks - travel, visitors, being left alone.
The wider Clover+ range covers joints and mobility, digestion, and skin and coat, all in the same daily treat format.
Shop Clover+ Peaceful Pooch →Adaptil - dogs
Adaptil is the best-known dog pheromone range and the one most vets will name first. Clinically studied, odourless, and safe alongside other treatments.
Where to start: the Calm Home Diffuser in the room your dog settles in, running from two weeks out, with a refill in the cupboard - Irish firework season runs well beyond the 31st. The On The Go Collar covers dogs that travel or spend time away from home, and the Travel Spray handles bedding, crates and car journeys.
Shop Adaptil →Feliway - cats
Feliway is the cat equivalent, and the range is more varied than people realise because cats get stressed about more than noise.
Where to start: Feliway Classic is the general-purpose choice for noise, change and new environments. Feliway Optimum is the enhanced formula for cats that are anxious across the board. Feliway Friends targets tension between cats in a multi-cat house, which a stressful night tends to inflame. There is also a spray for carriers and bedding, which is the one to have before a vet trip.
Shop Feliway →Pet Remedy - every species
Pet Remedy takes a different route - a valerian-based blend rather than a pheromone, which means one product works for dogs, cats, rabbits, guinea pigs, birds and horses alike.
Where to start: this is the obvious pick for a mixed household, or for small animals, who are rarely catered for by anything else. The plug-in diffuser for the main room, or the calming spray for bedding, hutch covers and carriers. The spray is also the best thing on this page if Halloween has crept up on you.
Shop Pet Remedy →VetIQ Serene and Johnson's
The tablets-and-drops end of the range, for when you need something on the day. VetIQ Serene covers calming tablets, an Xtra Calm strength for pets that need more, and calming drops that are easier to hide in food for a fussy animal. Johnson's Calm-Eze tablets do a similar job.
Where to start: match the product to your pet's weight, give it a few hours before the event rather than once the noise has started, and treat it as a top-up to a diffuser that has been running for a fortnight rather than a replacement for one.
Shop Calming Tablets →NutriPaw - calming chews and toppers
NutriPaw make a calming chew and a powder topper that stirs into food, which is the easier option for a dog that inspects anything new in the bowl. A natural supplement route if you would rather not use tablets.
Shop NutriPaw →ThunderShirt and Petlife KarmaWrap
The pressure wraps. ThunderShirt is the original and best known; the KarmaWrap is the more affordable alternative. Both need a correct fit to do anything, and both are worth testing on an ordinary evening before you depend on one.
Shop Anxiety Wraps →Stacking Them Properly
Calming products work better in combination than alone, because each one addresses a different part of the problem. A sensible plan for a dog that struggles with fireworks looks like this:
- From two weeks out: daily calming supplement, and a pheromone diffuser plugged into the room they settle in.
- From a few days out: build the den, and spray the bedding so the smell is familiar rather than new.
- On the day: a calming tablet a few hours before dark if your pet needs the extra help, the wrap on if it works for them, and the den open.
Check labels before combining anything, and if your pet is on medication or has a health condition, run the plan past your vet first.
Not sure where to start? Our teams in all 14 stores deal with this every October. Tell them your pet's species, weight, how bad the reaction gets and how long you have, and they will point you at the right format rather than the most expensive one.

Frequently Asked Questions
Which calming product works fastest?
A calming spray, applied to bedding about fifteen minutes beforehand. Tablets and drops come next, needing a few hours. Diffusers and daily supplements are the most effective overall but need roughly two weeks, so they are a planning tool rather than a rescue.
Can I use more than one calming product at once?
Yes, and it usually works better than one alone - a diffuser, a daily supplement and a sprayed bed all target different things. Check the labels, and if your pet takes medication or has a health condition, confirm the combination with your vet.
Will a calming product make my pet drowsy?
No. These are not sedatives. Your pet should stay alert and behave normally, simply with a lower reaction to whatever usually worries them. If a pet seems genuinely drowsy, stop and speak to your vet.
Can I use a dog calming product on my cat?
Not the pheromone ones - Adaptil and Feliway copy different, species-specific chemicals and do not cross over. Pet Remedy is the exception and suits every species. Always check the label for species and weight.
Do calming products work for rabbits and guinea pigs?
Pet Remedy does, and it is the main option for small animals. They are prey species, so their fear response is to freeze silently rather than make noise - a very still rabbit is not a calm rabbit. Spray the hutch cover rather than the animal.
My pet is still distressed even with calming products. What now?
Talk to your vet. Severe noise phobia - panic, escape attempts, self-injury, refusing food the next day - is beyond what an over-the-counter product can manage, and prescription options exist. They work far better planned in advance than reached for mid-panic.
