Why should I include vitamins & supplements in my pet’s diet?
Most commercial pet foods include baseline vitamins and nutrients, but some may not have the adequate amount to suit your pet’s exact health needs.

Consult your veterinarian to determine the best vitamins and supplements for your furry friend.

It is recommended to give the suggested dosage based off your pet’s weight. Please refer to the Feeding Instructions tab and consult with your veterinarian for more information.
Is this supplement safe to use with the medication my pet is currently taking?

Say “Yes” to Less Stress
Prolonged stress and anxiety can cause your dog to act out or even make him ill, leading to issues like inappropriate marking, chewing, aggression and even digestive problems. Composure helps calm dogs with a synergistic blend of colostrum, L-theanine and thiamine, to address stress and stop problems in their tracks. Just give your pup the tasty soft chews or liquid formula at the first sign of stress behavior or during stressful situations.&n


Manage Daily Stress
Composure can be given every day to calm anxious dogs and help those in new and stressful situations cope. The non-herbal, non-pharmaceutical formula has no known side effects and won’t make your pal drowsy or change his personality—he’ll just be his best self! The yummy chews come in three delicious flavors your buddy will love.
Fast Acting, Long Lasting
Composure starts working within 30 minutes, so you can give it as soon as you notice stress behaviors or before stressful situations like trips to the vet. Fireworks, thunderstorms, separation anxiety or just plain old fear don’t need to ruin your pup’s day anymore. The formula keeps working for up to 4 hours, so your best buddy can weather any storm.


Fully Researched Ingredients
The ingredients in Composure have been extensively researched and recognized for their calmative properties. Colostrum Calming Complex helps relieve stress and improve cognition, L-theanine relaxes and lessens irritability, while thiamine acts on the central nervous system to induce calm. All three work together to produce pleasant state of balance and well-being.
Use More if You Need It
During times of heightened stress or when you’re expecting stressful situations to arise, you can safely double or triple the dose. Give extra when phobia triggers arise like noise, encounters with new people or dogs or trips to the vet. The natural formula won’t impair your pup and isn’t addictive like some pharmaceuticals.

Amazing Product
By Kendra on Feb 9, 2021
This product has done wonders for my two dogs. I have a Golden Retriever that is known for being a Nervous Nelly. She gets stressed from thunderstorms and loud noises. A veterinarian recommended this product as a beginning step (before putting her on actual medication) and it has worked great. While she still has some nervous spells, this has greatly reduced them. I have another dog (a Corgi) that will eat anything he can get ahold of. After putting him on this product (as my Golden was getting it and I wondered if it would help him) he has calmed way down and doesn't feel the need to look for food every second (I believe he was a stress-eater who ate when he didn't know what else to do or became This product has done wonders for my two dogs.

Both dogs think these are treats and are extremely happy to get them. Once again, I highly recommend it for behavior problems in general. … more

Unfortunately Not for Us
By Thea on Feb 11, 2021 Top 1000 Contributor
I had high hopes for this supplement based on a recommendation from a friend. Even at 3 times the dose it did not help calm my dog. She gets anxious when she is kenneled away from home - barking, whining, crying in her kennel for hours at times. I even tried long walks plus the supplement then kenneling her, but nothing. We are working on other training methods to help her calm down instead. I will donate these to the friend who had success with these.

Hyperactive Golden Retriever
By Connie on Feb 7, 2021
You people are so nice. Everyone I talk to is pleasant and helpful. I do not expect Chewy to continue to help me with my overly active Abby. I doubt anything is going to calm her down. I truly appreciate everything Chewy has tried to do. I am quite sure this is a good product; it doesn't do a thing for Abby nor do I think anything will. I do love her but there are times I could, well I actually do, scream.

Anxious Rescue
By Daryn on Jan 7, 2021
I adopted my rescue with severe anxiety. We have struggled with finding ways to make him more comfortable when we have guests over. This did the trick within 20 minutes he was a lot happier and calmer. It was like a completely different dog. Highly recommend for anxious dogs. Side note: We have a very energetic aussie pup that this works part of the time. It does help mellow him out at times because he tends to get overly excited when we travel or have guests over.

Works well at a doubled dose
By Beaglemom on Jan 3, 2021
My 2 beagles are much happier sleeping in their crates when they have these. It does not make them overtired in the morning which some other products have. They also have no issues waking up to go out to potty if need be. I double the recommended dose routinely and have not seen any bad side effects. My older beagle is very sensitive to chicken and beef dog foods and some meds. She has no issue with that at all. She has had reactions to other “vet recommended “ calming products so I plan to stay with these.

Back to our old evening routine!
By TTmom on Jan 5, 2021
We work from home and take play breaks with our TT but she always wants more action. We all need some down time evenings but that’s when our girl wants the most attention and shows it with Whining incessantly! She used to lie on the sofa with us before Covid days and working from home. I tried other herbal soothers but this brand seems to get her to settle into our usual evening routine! This has shown her she’d rather get her tummy rubs on the sofa!

excellent product
By katmom on Feb 14, 2021
These chews work! My one dog is terrified of thunder and fireworks. He has had a thundershirt and benadryl, but these chews work better! According to package instructions, one can give more than one if necessary.

Not for serious anxiety
By Emily on Dec 26, 2020
I have two dogs, one with general anxiety and one with separation anxiety, and unfortunately this product didn't seem to do anything for either of them. To be fair, the main ingredient *does* have scientific studies verifying its effectiveness, so for a dog with low-level anxiety I can envision this product making a difference if used in conjunction with other OTC therapies. It just doesn't do anything for dogs with more advanced issues.

Absolut wirksam und sehr hilfreich für nervöse und ängstliche hunde
By Mocca on Nov 27, 2020
wir bekamen es für 1 shelterhund und einen strassenhund, die beide bei uns ihr körbchen fanden. beide hunde sprachen gut auf die bröckchen an und ihr verhalten war wesentlich gelassener. es ist kein schlafmittel und kein tranquillizer, sondern arbeitet mit in der natur in der muttermilch enthaltenen beruhigungsstoffen, die die welpen bekommen, wenn sie gesäugt werden. unsere hunde sind bereits 3 und 4 jahre alt und erhalten es täglich und wie gesagt, ihr verhalten ist im wesentlichen gelassener geräuschen und anderen sie störenden umwelteinflüssen gegenüber. ao lange wir es erhalten können, werden wir es unseren hunden geben.

Calming Treats
By HelensMom on Feb 23, 2021
Helen doesn't like rain or thunder. When I'm able to give her "Composure" before a storm, she seems to be calmer and stops shaking.
