Most calming supplements rely on a single ingredient. CALM+CHILL naturally supports healthy stress levels and promotes relaxation and calmness across four complementary areas. Because stress in pets is rarely one-dimensional.

Natural herb support

A healthy gut microbiome plays an important role in your pet's calm and balanced behaviour. Our targeted probiotic complex supports a healthy gut microbiome and helps promote calmness from the inside out.

Got CALM+CHILL Questions? We're Here to Help.
From daily use to serving suggestions, find answers to the most common questions about CALM+CHILL. Still wondering about something? Just reach out. We're always happy to help.
How do I start my pet on CALM+CHILL?
For most healthy adult cats and dogs, you can start at the full recommended daily amount immediately based on your pet's weight.
If your pet is particularly sensitive or has a history of supplement sensitivity, we recommend starting at half the amount for 3–5 days before increasing.
Always consult your veterinarian if you have any concerns.
Can I give CALM+CHILL every day?
Yes. CALM+CHILL is designed for daily use. Consistency is key. The benefits of daily nutritional support build over time, and many pet parents use it as a permanent daily addition to their pet's routine.
What is the Rescue Dose?
In times of need, the daily amount may be doubled for that day only.
If your pet is receiving behavioural medication, consult your veterinarian before increasing the daily amount.
My pet is on prescription medication. Can they take CALM+CHILL?
If your pet is receiving any behavioural medication, we recommend consulting your veterinarian before introducing CALM+CHILL or any new supplement, and before increasing the daily amount.
How long before I see results?
Every pet is different. Some pet owners notice changes within the first few days.
For the full benefit of daily nutritional support. Particularly from the probiotic complex and DHA, allow 4–6 weeks of consistent daily use.
Should I split the daily amount across meals?
Yes. For best results, divide the daily amount across morning and evening meals.
This helps maintain consistent support for calm, relaxed behaviour throughout the day.
Can cats take CALM+CHILL?
Yes. CALM+CHILL is formulated for both cats and dogs. All cats use the same daily amount: 1 scoop (3 g) per day regardless of weight, up to 10 kg.
Can I give CALM+CHILL alongside other Tandem Super Blends?
Yes. CALM+CHILL is designed to complement the Tandem Super Blend range and pairs particularly well with PRE+PRO for comprehensive gut health and nervous system nutritional support.
Is CALM+CHILL suitable for puppies and kittens?
CALM+CHILL is formulated for adult cats and dogs. If you are considering it for a younger animal, please consult your veterinarian first.
I have the pleasure of owning 2 miniature schnauzers who led very sheltered lives, with a DogsNZ breeder on a quiet property in rural Waikato, before being rehomed with me. I have had Reily 3½ years and Quita 2 years.
Reily was reserved and reactive when in a stressful situation. She was terrified of anything unknown, car travel, neighbours, traffic on the road etc. She slowly improved but I still had concerns about her nervousness which manifested as agression sometimes. Quita was more confident and has adjusted to her new life more quickly. She loves people but was unable to socialise well with other dogs, which has been difficult when walking on the beach everyday where I live.
I had no issues introducing CALM+CHILL to the girls. They love the taste and lick up every last crumb in their bowls. The change in my girls has been remarkable. Reily is still a bit wary of new experiences but is more inclined to be curious rather than frightened. She's a changed girl, confident, happy, playful and keen to meet people and other dogs. Quita, although always confident and fond of people, has become much calmer and less confronting around unknown dogs. She has a very relaxed (chilled) way about her now. Walking her is much more fun!
I am so pleased with the changes CALM+CHILL has made in my 2 girls lives, especially Reily. She has a real love of life now rather that being constantly fearful. I have enjoyed seeing her grow in confidence and show her real, cheeky, loving personality. I have even had my neighbour asked what has happened to Reily as she's so full of bounce, playful and happy now. That says it all!
When Mika our 12 year old Siberian Husky lost her best friend of 11 years, her whole world flipped upside down💔
Mika has always been sensitive, but after Roko passed she was constantly pacing, barking, trying to chew her way into the house when we left and even ripping pieces from the fence trying to escape and find us. She was genuinely panicking and starting to hurt herself in the process 😞
With help from our trusted vet, Mika was started on an medication daily to help keep her calm while we were at work. We knew this wasn’t something we wanted long term, so we started trialling CALM+CHILL alongside her treatment.
The difference has honestly blown us away ❤️ Mika is now completely off medication and with CALM+CHILL as part of her routine she is noticeably calmer at home, can self-settle when we leave and her pacing has reduced significantly.
For us, the pacing was one of the biggest signs of her stress, so seeing that change has meant everything. CALM+CHILL contains ingredients chosen to support calm behaviour and help dogs manage stress and while every dog is different, we’ve genuinely seen a difference in Mika.
After losing her best friend, we just wanted Mika to feel safe and like herself again. Seeing her finally able to relax has been incredible. 🥹❤️
We’ve been trialling CALM+CHILL with Max for the last few months and honestly, the difference has been life changing.
Max is the definition of an over excited, highly stimulated Staffy. He feels everything at 110% and while his enthusiasm is one of the things we love most about him, helping him regulate and settle himself at home has always been a challenge.
Since introducing CALM+CHILL into his routine, we’ve noticed such a positive change in his ability to switch off and regulate himself. He seems calmer, more settled and much better able to manage all those big Staffy emotions without constantly needing to be on the go.
What we love most is that it hasn’t changed who Max is, he’s still his cheeky, cuddly and energetic self but he seems to have found a much better balance between excitement and calm.
After several months of using it, we can genuinely say that CALM+CHILL has made a huge difference to our everyday life with Max. It’s become a regular part of his routine and we wouldn’t want to be without it.
Tandem’s new CALM+CHILL is not “just another ashwagandha” product out on the market. They have worked very closely with Massey to pick the right ingredients that help & support one another for our cats & dogs.
We used to sprinkle plain ashwagandha on Lucy's food prior to big events to help her nervous system, which we saw great results with but when Tandem told us about their specialised formula we knew we had to give it a try as I trust that they had a reason for each additional ingredient.
Lucy loves CALM+CHILL so much that she will happily lick it straight from the container, but it’s also suitable for sprinkling over their meals or turning it into a warm fluffy for the pups to enjoy on a cold winters morning..
I have personally seen a major improvement with Lucy as the additional ingredients compared to only ashwagandha have helped her regulate emotions and reactivity in new or unsure environments, Lucy has always been a quieter dog with new places or situations, I have noticed her being more confident & trusting that something isn’t always going to happen when she tries something new.
We started using Tandems CALM+CHILL Powder with Cooper after weaning him off his medication, and I’ve been genuinely so impressed with how well he has been doing.
Coming off medication was something I was quite nervous about. I wanted something that could give him a little extra support while still allowing him to be completely himself.
Since adding CALM+CHILL to his routine, we’ve continued to see so much progress. He seems more settled, is recovering from stressful situations much quicker, and we’ve had some really positive experiences out on walks and around other dogs. He’s still Cooper, it hasn’t changed his personality or made him sleepy or “zoned out”, he just seems better able to cope when something does worry him.
CALM+CHILL is only one part of the picture alongside all of the training and confidence building we’ve done with him, and every dog is different, but for Cooper it has become a product I’m really happy to keep as part of his daily routine.
Bo is a 5 year old GWP. IYKYK,
He has always been one of a two dog household and has a selected human out of the family. If either of them are away from him he would pace, stress pant, destroy stuff and generally have a terrible time. The reunion with his human is always really intense. Loud noises also stress him out.
Being part of this trial has been a actual god send for Bo. During the trial he’s has some massive changes which I believe it would have been so hard on him if it wasn’t for CALM+CHILL.
In the first few weeks his human who has always worked from home with him has started working away from the house and 5 weeks ago his companion dog passed away.
Since being on CALM+CHILL he calms so much quicker in a stressful situation, he hasn’t destroyed anything when left alone. And when Duke passed he acclimatised well. He now also chooses to settle himself alone if his human is busy in the house instead of being constantly at her side and reunions are much more calmer.
An added bonus is that CALM+CHILL hasn’t dulled Bo’s personality, just given him a calmness that helps him regulate himself.
We had the privilege of trialing CALM+CHILL from Tandem, and it has made a noticeable difference in helping manage Alfie’s stress levels.
We first started using CALM+CHILL when we moved houses. Moving was a big change for Alfie, but with the help of CALM+CHILL, he was able to settle into the new house relatively smoothly. There are still some areas we’re working on, but the difference compared to how Alfie is without CALM+CHILL is significant.
Alfie is also a very energetic dog. Even after going on adventures for 2+ hours, he would come home and immediately look for his ball to play again. One of the biggest changes we’ve noticed since starting CALM+CHILL is his behaviour at night. Alfie used to take a long time to settle and would constantly seek attention or want to play. Now, he is much more relaxed and can peacefully chill without needing to play every second of the evening.
At his previous vet, Alfie was never interested in being patted or interacting with the staff. Since starting CALM+CHILL, he has come a long way. He’s made lots of human friends at the new clinic and has even started giving the team lots of kisses, which is very unlike him!
Of course, he’s still hesitant when it comes to actual procedures, but CALM+CHILL seems to take the edge off and helps him stay a little more relaxed.
Every little bit counts, and that’s why we’ve been loving CALM+CHILL.
