Finally a good product!

My dog, Layla, is terrified of loud noises, such as thunderstorms and fireworks. Nothing helped her until we tried these. No more racing heart! There’s been times I worried she’d have a heart attack. Layla is still nervous, but much calmer, not fully terrified. I shared these with some friends, all with the same results. Dogs ranging from 10 pounds to 80. Last week’s 4th of July fireworks was a testament for all of them feeling relief. Not every animal has the same metabolism. Hopefully, you see the same results I’ve seen with these chews. I’ve had horrible experiences with hemp products, but for some, it helps.

Very Greatful!!

I am so Thankful that I found these, well I should say DaisySue is happy. Just in time for the #4thofJuly All the Bangs and Booms normally send her into a frenzy and runny for whatever hiding place she can find. Gave her 1 earlier today...during the thunderstorms and she was ok but I knew tonight would be worse, so gave her another one around 6pm. Wow.. no panicking, panting, shaking, hiding!!! She layed by me feet for a little bit (while I was working) then just snuggled up under the blanket on the bed with her sister and went to sleep!!!. AMAZING!!. And she wasn't "zoned out" like some drugs can make her. Just chilled. We are now prepared for this stormy season... I don't have to worry about her having a heart attack during the next bad thunderstorm. I'm definitely keeping these on hand!!!

Worked okay but made my poor pup sick both times

I have a 15 lb Chihuahua mix. The first time I gave her a full shew and she threw up several times all night and into the morning. The second time I gave her 1/2 and she didn't throw up (at least not in the house where I saw/ heard/ found it). The third time I gave her 1/2 and I thought she was okay but she threw up later that night. SIgh, too ad because they seemed to calm her a bit before they made her sick.

I am not sure if this works or not.

I gave 4 chews to my 70 lb. Pitbull on the 4th. But he still got the zoomies when he heard the neighborhood fireworks. I had to let him out to run until he was exhausted. My Chihuahua refuses these chews.

Seemed to help

I have an extremely fearful older dog that I tried everything: Thundershirt, milk and honey, thunder pills from petstore. I am so afraid my dog will have a heart attack! I gave her this product and she seemed to do better during a brief storm. I will know better when severe storm hits.

great product

I'm ordering ahead of time for the 4th of July 'Helliday' since it's mid week, boomers will be going off for abotu a week locally. Also popped a couple over Memorial Day weekend, as some folks thought it was an 'early 4th'. He still notices them but instead of freaking out, he barks at the boomers...I can live with that !

Really works

I’ve never tried anything like this during storms and we’ve had several lately. I gave Molly one of these and it calmed her!! She didn’t pace as much but got under the bed. I didn’t hear her and we weren’t up all night! Thank you for this product!!!

These work

These helped take the edge off the anxiety my pups experienced when we had strong thunder storms, and Fourth of July [and the entire week after] fireworks.

These Really Work!

I have a 10 yr old Springer who is deathly afraid of loud noises including thunder and fireworks. I have tried everything including tranquilizers which she tried to fight through and it was dangerous for her to be on her feet. After one try with these chews, there was an enormous difference and she just curled up on the floor and ignored the thunder. Never did I think these would work but they do!
