We can sleep again
Our 6 month old puppy came to us with stomach and regurgitation issues, and developed terrible separation anxiety while she was sick to the point where she couldn’t be left alone for a second without crying and barking. She wasn’t sleeping properly and would whine for attention around the clock. We have been giving her Calming Care for about 3 weeks now, and suddenly it’s like a switch was flipped. She goes in her crate voluntarily, she naps peacefully throughout the day and doesn’t freak out when I leave the room. She sleeps through the night in her crate outside of our bedroom without an issue. I really think this product has contributed to reducing her anxiety, along with a steady diet and a healed gut. Highly recommend you give it a try.

Noticeable help with anxiety
We have an anxious golden retriever that often struggles with separation anxiety. Rather than go with prescribed medication, our vet recommended we try the Calming care to help with comfort and overall gut health benefits. We have noticed a gradual increase in anxiety energy level changes to a calmer version of our golden. Our dog loves the flavor and smell as well drop the powder on her daily food. Additional benefits of this supplement is decreased anxiety and overall better health longevity for fury family member.

Works for anxiety from howling coyotes!!!
We could not sleep because our female shepherd could not sleep. The coyotes after almost 30 years I saw them in our subdivision during the day. And, at night I hear them howling. It’s been a rough winter here I am in Illinois 15 miles from Indiana. I understand it’s mating season. The hawk population has exploded out here. And we now have eagles. I haven’t seen many rabbits in years. They are hungry . I mixed this in a little milk and my shepherd drank it right down. After 3 days it worked. She’s small 52 pounds. She was trying to wrap herself around my head. All this happened when I just hit home from back surgery. Her fireworks meds didn’t work but this sure did

Great product for anxiety in dogs!!
This supplement has done wonders for my mix pit with fear and high anxiety..this is not a magic powder that’ll make all the anxiety go away there has to be effort on the owners part to work and help their dog find ways to ease up during stressful situations..basic obedience and calming techniques have helped my dog for over 2 months on the supplement of course I work with him daily to put his fears and anxiety at ease..it is a great product and I have seen significant change in my big 1 year old pit..again with both of us working together along with the daily calming supplement had done wonders for him!!

Did some things good
This product did not calm my dog but did wonders for her stomach. No calming effect that I could see but improved her eating.

Saved Our Rescued Scared Barking Dog
We have been trying to rescue an abandoned Mama dog with her puppies in our neighborhood. She is very thin, and living in coyote territory makes it dangerous for her and her babies. Finally, we managed to save the puppies, but Mama dog was acting aggressively and barking all day out of fear and stress. We left food nearby, which she ate, showing her trust. We thought that maybe a combination of wet dog food and calming powder could help her relax. Before that, we safely mixed a dewormer into her food bowl. The next meal, we added one packet of calming powder to the wet food. She ate everything without hesitation. After a few days, her behavior softened, and she became more gentle and approachable. We carefully put a leash on her and brought her into our kennel for a night, then transferred her to our garage. The calming powder seemed to work wonders—perhaps it helped her release stress hormones. Since it’s a probiotic, it’s possible that the combination with the dewormer allowed her body to absorb nutrients better. After weeks of cautious, defensive behavior and barking to protect her babies from humans and coyotes, she gradually lowered her guard and allowed us to pet her, saving her life and her puppies. We fed her one packet of powder per meal, twice daily for five days. It truly made a difference. Now, Mama dog is gaining weight, looking healthier, and beginning to heal. We’ve found a wonderful foster home with a secure backyard, where she can recover and be loved. Our goal is to help her find a forever home where she’ll be cherished and safe.

Works well but this is TOO HIGHLY PRICED, same as Probiotics Bifidobacterium Longum BB536
This probiotic works VERY WELL in perhaps most dogs. We are so much a product of what is colonizing our guts, human and beast alike! We don't even realize that what we eat AFFECTS WHAT WE THINK (this is an entire field of research and it is fascinating and well established!) This is a HIGHLY DESIRED PROBIOTIC, but PURINA IS CHARGING TOOOO MUCH FOR THIS PROBIOTIC ... (current pricing January 2024 is over a dollar a day! Available in January 2024 in other packaging for less than 25 cents per day!) ...simply because of their name, the perceived exclusive access, and some broth flavoring. >>> Instead, search for Probiotics Bifidobacterium Longum BB536 ... Available here on Amazon, and save yourself a lot of money, and send a message to Purina that we consumers can research medical literature and figure out that Bifidobacterium Longum BB536 is the EXACT SAME probiotic! Some bacteria have been given a different name in the past to now, the same as plants can have more than one botanical name -- actually they have an older name and a corrected updated name. It is common for example in te plant trade for nurseries to not give up an old botanical name and yet current scientific literature has the new botanical name. So one must know both names to learn accurate information about such particular plants. That is what is happening here. Research it for yourself if you desire on Google Scholar and other published science search sites. It did take me a day of research to figure it out, but I had a hunch that since I could not find this name ANYWHERE --- WHY IS THAT??? -- that there was perhaps another name at play. Why would Purina be the ONLY access to a particular probiotic??!!! That answer is: THEY ARE NOT THE ONLY ACCESS. And what else is happening here is that Purina has found a lifesaving control for anxious pets, and priced it obscenely high. Search for BB536 and save yourself a heap of money. Break open the capsules and sprinkle on pet's food. Watch their calmness levels increase. Highly recommend the probiotic. I do use other of Purina's products for quality at a decent price. Wake up Purina and stop gouging the public.
