Short answer. Most calming chews are dosed by body weight and given every day, not only on the bad day. Trueleaf's Calming Support chews are one chew per 10 lb of body weight a day, so half a chew for a 5 lb dog and ten for a 100 lb dog. The common calming ingredients, L-theanine, chamomile and lemon balm, are studied for supporting a relaxed state rather than for sedation, so what owners describe is usually subtle and shows up over days rather than minutes. Give it two to four weeks of consistent daily feeding before you decide either way, and give it at the same point in the day rather than around events.
How much calming chew should I give my dog?
By body weight, every day, at roughly the same time. Splitting the daily amount between morning and evening is fine and is often easier on a small dog's stomach.
| Body weight | Chews per day |
|---|---|
| 5 lb | ½ |
| 10 lb | 1 |
| 20 lb | 2 |
| 30 lb | 3 |
| 40 lb | 4 |
| 50 lb | 5 |
| 60 lb | 6 |
| 80 lb | 8 |
| 100 lb | 10 |
| 120 lb | 12 |
| 140 lb | 14 |
The calculator on any Calming Support product page shows the same table for the pack you are looking at, which is the safer place to check if you are between sizes.
During times of increased stress, the pack says it is okay to double the daily amount, as needed.
If your dog is on medication, pregnant, nursing or has a diagnosed condition, talk to your veterinarian before starting any supplement.
What is actually in a calming chew?
L-theanine. An amino acid found in tea leaves, and the most researched of the calming ingredients in companion animals. It is studied for supporting a relaxed but alert state rather than for sedation. Trueleaf uses AlphaWave L-theanine, a branded form. Research in dogs exists, the studies are small and results vary between individual dogs.
Chamomile. Long traditional use for supporting calm. The veterinary evidence base is thinner than the human one, and it is usually included as part of a blend rather than on its own.
Lemon balm. Melissa officinalis, usually paired with L-theanine or chamomile. Most of the research is in humans.
Hemp seed oil and hemp seed powder. This is the part most often misread. Hemp seed is a food ingredient, a source of Omega-3, 6 and 9 fatty acids and protein, the same seed sold in grocery stores. It is not a plant extract and has no sedative effect of its own.
One thing worth asking of any brand, including ours: what is the amount per chew? A label that names L-theanine with no milligram figure beside it tells you nothing about whether the amount matches what was studied. Ours are on the ingredients page.
How long should I give it before deciding?
Two to four weeks of daily feeding before you decide either way. That is the honest answer, and any product promising a same-day transformation is overselling.
Here is a method that beats impressions. Before you start, pick one specific countable thing. Minutes of pacing before you leave the house. Number of times they bark at the window between five and six. Whether they settle within ten minutes of you sitting down in the evening. Write the number down for a week before you start anything, then again in week four.
Memory is generous and inconsistent. A count is neither. Most owners who tell us something did or did not work are describing a feeling, and half the time the written numbers say something different.
If nothing has changed after four weeks of consistent daily feeding at the right weight band, this is not the right product for that dog. The next step is a conversation with your veterinarian about behaviour, not a second supplement.
What a supplement will not fix
Separation distress, noise sensitivity and reactivity are training problems. Sometimes they are medication problems too. A supplement sits alongside behaviour work. It does not replace it.
A supplement sits alongside the work that carries the weight: desensitisation done properly, a predictable routine and a managed environment. Blackout blinds and a white noise machine on fireworks night will do more than anything you can feed. For a full checklist, see Halloween fireworks and your dog or cat: how to get ready.
If your dog is destroying doors, injuring themselves or panicking to the point of not eating, that is a veterinary behaviour case today. Not a supplement case.
Chew or oil?
Calming Support Chews are easier to dose and most dogs take them as a treat. The Calming Support Oil suits dogs who spit chews out, dogs on a restricted-calorie diet and anyone who would rather mix it into food. Same ingredient family, different delivery. The chews come in 90 g, 200 g and 600 g bags, and both formats sit in the calming range.
Some owners run the chew daily and keep the oil for travel, because a dropper bottle is easier to manage away from home than a bag of chews and a measuring decision. The full comparison, with both dose tables and cost per day, is in chews or oil: how to choose the format.
Common questions
How much do I give?
By body weight, daily, using the table above or the calculator on the product page.
How long should I give it?
Two to four weeks of consistent daily feeding, judged against a behaviour you counted before you started.
Can I give a calming chew and a joint chew on the same day?
Yes. They are different formulas and the daily amounts are worked out separately by weight. Do not reuse one table for the other, because the weight bands differ. Our hip and joint guide has that table.
Will it make my dog drowsy?
The ingredients are studied for supporting a relaxed state rather than sedation. If your dog is noticeably sleepy or unsteady, stop and speak to your veterinarian.
Is it going to make my dog drowsy? No. Hemp seed oil and hemp seed powder are nutritional ingredients, not sedatives.
What if they will not eat it?
Try it in food, break it into pieces or move to the oil. Do not introduce it on the same day you change anything else, or you will not know which change caused what.
Can I use it just for fireworks or a car trip?
It is a daily supplement, given by body weight, rather than something to reach for on the day. Follow the amount on the pack.
When to talk to your vet instead
Any sudden change in behaviour deserves a veterinary appointment before a supplement, because pain is a common and easily missed cause. So does anything that is getting worse rather than staying the same. A supplement is for supporting a dog who is basically well. Your veterinarian knows your dog's history and we do not, and nothing on this page is a substitute for that conversation.
Not sure which one fits your dog? Try the supplement finder. A few taps and it picks the product, the size and the daily amount.
