Every dog is different, just like people. Some just can’t handle a lot of noise, being left home alone, or changes in their environment very well at all. I get that…

Heck, if I had known there are products out there like this, I could’ve used these many years ago….

No, I did NOT mean me, lol!

I meant for our dog, which suffered from severe separation anxiety when he was young!

These are NOT for us humans, BTW! Only for our beloved canine friends. *

Honestly, I’ve never tried these on my dogs since I haven’t found any of them to have anxiety issues to the point that I’d need something to calm them down, at least not anymore.

But, I do realize many dog owners do need help with their over-energetic, anxious dogs…remember, I went through that before…

Anyways, back to the point here…The Review!

The Composure Chews are highly recommended by MANY Dog owners on Amazon’s product reviews. The number of good reviews there is the reason I thought I’d check them out more.

After reading a lot of these reviews, I thought I’d write my own review in the hopes of helping you decide whether or not to use them for anxiety issues with your dog. So, again, I’m basing this on what other dog parent’s are saying and also the product information given from Vetri-Science.

What are Composure Bite-Sized Chews?

Vetri-Science-Composure-Chews-ReviewThese are basically a soft chew made for dogs containing many natural ingredients to help calm dogs down during stressful situations.

These chews will help your dog remain calm and relaxed during  times that may have caused a lot of anxiety and stress for both of you.

These frightful situations may include fireworks, thunderstorms, car rides, trips to the vet or groomer, etc.

The chews shown above are also recommended for use with hyperactive dogs, nervous dogs, and dogs going through separation anxiety.

What Makes Them Work?

According to the information given by Vetri-Science these chews work by using three active ingredients. These are the C3 Colostrum Calming Complex, which are made from proteins, L-theanine (which is an amino acid and derivative of glutamic acid),  and Thiamine (vitamin B1).

The C3 Colostrum and L-thanine are bioactive with your dog’s body and work with it to calm your dog down without it becoming drowsy or dopey. Thiamine is added since it has been found that dogs low in Thiamine are often confused, anxious, and may even have muscle weakness or spasms.

Thiamine also known as vitamin B1 is known to affect the nervous system and help to calm and soothe dogs.

Active Ingredients

  • Thiamine (vitamin B1) –  134 mg
  • C3 Colostrum Calming Complex – 22 mg
  • L-Theanine (SunTheanine brand) – 21 mg

Inactive Ingredients

  • Brewer’s yeast
  • canola oil
  • chicken liver flavor
  • citric acid
  • glycerin
  • mixed tocopherols
  • propionic acid
  • proprietary blend (maltodextrin, sodium alginate & calcium sulfate)
  • rosemary extract
  • silicon dioxide
  • soy lecithin
  • vegetable oil.

That’s it….according to the ingredients list on the back of the bag that is what these chews contain.


  • Easy to give – no mess
  • Appears to work for most medium-large dogs with anxiety
  • Non-prescripiton (I’d still ask your vet what he or she thinks)
  • Easy to use weight chart to figure out how many to give according to dog’s size
  • Can increase number of chews if needed (read directions on bag)


  • Not quite sure where they’re made – only says where the Composure chews are distributed from which is Vermont, USA
  • No guarantee they’ll work – but with every dog being different, that’s kind of a given
  • Main ingredients appear to be natural, but not too sure what some of the inactive ingredients are made from such as the chicken liver flavor, mixed tocopherols, silicon dioxide, and the proprietary blend listed.

Overall, I’d give Vetri-Science Composure Bite-sized Chews a try if I found one of my dogs needed something to help them get through anxiety issues.

After all, over 600 reviews on Amazon and most of them being over 4 stars or more, I’d figure these a safe alternative to prescription medicine to at least try.

Hey, why not give them a try with your dog?

I’d think these much better than having your dog and you suffering through severe anxiety issues. These bite-sized chews help a lot of other dogs out there with no side effects or addiction to them either, at least as far as I’ve read and heard about them.

*Please NOTE!* Remember, do ask your veterinarian before trying these out on your dog. I’m not sure how these may react with other supplements, prescriptions, etc. that your dog may be taking or how it will affect any type of existing condition your dog may have.

I do hope you’ve enjoyed reading this review and if you have any questions, please feel free to ask!

Have you tried the Vetri-Science Composure Chews for your dog’s separation anxiety or any other anxiety issues?

  1. I have a nervous one year old whippet boy. He drools in the car and is very destructive when left in the house even when he is accompanied by a very well behaved almost 3 year old whippet girl. He chews anything and everything, he paces all day long and gets into all kinds of trouble. These chews don’t work and neither did the other two supplements I tried before these. A nervous dog is a nervous dog and short of a lobotomy or drugs which could put him in a semi-coma state, I think I am stuck with this guy.

    • Hi Tara,
      Thanks for stopping by and commenting here. Sorry to hear you’re having these problems with your one-year old whippet boy. It does sound like he is an extremely anxious pup for sure! If these didn’t work and neither did other supplements that you’ve tried, I’m wondering if there could be another reason for his behavior…maybe an underlying health problem or pain issue that isn’t physically apparent. Of course, all dogs, like people, are different and some things work great for some dogs, while for others they won’t work at all.

      I’m not a veterinarian, and although it could just be an extreme case of anxiety, I’d recommend taking him to your veterinarian and have him checked out thoroughly and explain what he does exactly to your vet. Another thing that could hopefully help is more exercise. Usually daily exercise will help calm a dog down somewhat, and with yours being only a year old, I’m sure he has tons of energy!

      Although I’ve never had the experience of owning a whippet before, I do know whippets are related to the greyhound breed, and are considered to be sight-hounds. According to a few resources I looked up to make sure, they do need to run. So, if this is something you haven’t yet tried with him, it would probably at least help a bit. They are also considered to be a high risk for elopement, so make sure you let him run in a fenced in area. You probably already know that, since you own another 3-year-old whippet that is well behaved…but, I thought I’d add it just in case.

      Another thing about Whippets is they’re extremely sensitive…meaning that they may quit listening to you if you even yell at them one too many times. Even a stressful or noisy household may do it. Although these may not apply to you or your household of course, but staying calm and quiet have worked much better with my dogs behavior.

      I’m not sure what you’ve already tried as far as exercise, socializing, and training goes, but if your dog is acting this nervous and is getting into trouble you might also want to consider checking into some dog training that will help you get your dog to act much better. It’ll take time and patience, but you can do it! Although our dogs were different breeds we’ve been the parents of some tough ones, especially when they were pups!

      Anyways, I’d have him checked over for any health problems first, if you haven’t already, and if everything looks good with your veterinarian, I’d work on socializing and training next. It’s best to do it when they’re younger and it’ll help get rid of some of that energy, along with a good run at least a few times a week.

      If you need help with the training part of it, you can try bringing him to obedience classes or find a reputable dog trainer in your area. But, if that’s out of the option, or you just can’t find one you trust, you might want to check out an online dog training course. It helped our dogs behave so much better after I started using the techniques that are shown in their videos…it’ll teach you how to train your dog without a lot of stress and it’s not expensive at all. I know I learned a lot I didn’t know when I recently checked out these dog training courses and I definitely recommend them…I’ll have to check again on where you can check it out and I’ll add the link in another reply here as soon as possible…

      Please, do try to check again in a day or two and I should have it by then. Sorry about that, btw…it seems I’m having some problems finding the exact link to it, but I did contact the person that does this program to see if they still offer the courses and where I can find the link to see what they offer…it’s the best I’ve seen yet, so that’s why I want to share it with you…I really think it’d help your dog

      I’d love to hear again from you and how things are going with your dogs. I hope this has helped you out in some small way at least…wish I could be of more help, but without actually being there to observe and see what he’s acting like, and what other factors may or may not be contributing to his anxiety problem, it’s very hard to tell…again, do have a vet check him, just in case.

      Best wishes to you and your whippets! Hang in there…he’s a young pup yet, and all the dogs I’ve had have gotten much better as they’ve gotten older.

  2. My sister has a 10 month old Newfoundland. For the past 2 weeks she’s been giving him these calming chews, whenever she has company coming over to her house. Well, to make a long story short; they don’t work!!! She has gradually given the Newfie more, and he still misbehaves and jumps all over the people visiting. He’s just as bad on them, as he is when not taking them! I do not recommend Vetri-Science bahavior chews!!

    • Hi Gary,
      Thank you for letting us know what your experience has been with the Vetri-Science chews. I’m sorry to hear your sister’s puppy isn’t calming down when given these chews…and, Newfoundlands are a big breed of dog, so I can only imagine how big that pup already is at 10 months. Like I mentioned, I’ve never used these on my dogs myself…actually I’ve never tried any type of “calming” products on our dogs, which is why I’m glad you shared your thoughts here. If they aren’t working, I wouldn’t continue giving these to him.

      As for your sister’s puppy, I’m not sure how much exercise and training the puppy gets, but usually the more exercise, the less likely they are to be overly rambunctious. I’d probably take the puppy out for a good walk at least once a day…twice would be even better, especially if it doesn’t have a lot of room to run outside.

      Another thing she might try is if she knows ahead of time that visitors are expected, she could take him for a walk about 30 minutes prior to their arrival. This should help calm him down some. At 10 months, all of my dogs were pretty energetic and needed to be walked, play fetch, Frisbee, etc. Otherwise, they were doing the same thing and jumping all over everyone.

      One of our dogs, our Old English bull dog, Argon, still tends to go a bit crazy when visitors come to the door. Or up until recently, he did…

      Now, when I see we have visitors, before answering the door, I let him outside since we have a fenced in backyard. Once our guests are settled somewhat, I’ll let him in, but only on a leash. I’ll walk him in and let him greet our visitors, but I’ll keep his leash short enough so he can’t jump on anyone.

      I also try to keep his attention focused on me, and not the visitors by saying his name if I see he’s zoning in on them and starting to move too quickly towards them. I’ll make him walk slowly and keep getting his attention…this makes him lose interest in them a bit so he isn’t wanting to race over there and jump on them. Once I see he’s calm and settled, I’ll take the leash off, and he doesn’t bother anyone too much then. Before, he’d come in charging like a mad bull, barking and jumping on them.

      Another thing she could try is bring her puppy to a trusted trainer or dog obedience classes to get it under control before it becomes too big of a problem. He’s still a puppy, so now is the best time to teach him how to behave…much easier than when he’s older and even bigger. I hope your sister (and you) finds this helpful…every dog is different though. What works on some might not work on others. Just keep trying and reward him for good behavior only…no treats if he’s acting up. Eventually they learn, it just takes time and patience.

      Feel free to let me know how your sister’s dog is doing in the future…I’d love to hear, and if either you or your sister have any questions, I’ll be happy to answer the best I can.

      Thanks again for stopping by and best wishes!
