Worked great for my dog!

I have a WILD pit mix, who is very sweet but very "simple." He's not he easiest to train, but he's learning more everyday. This product helps calm him down, he listens better, he doesn't misbehave, he stopped chasing the cats, he doesn't eat like someone is going to take his food away, etc. etc. etc. Every anxious habit he had has been solved without making him sleepy or taking away from his loveable personality.

I came home after using these pills hoping to have some relief to the recent behavior that's started up with my new schedule. I've tried behavioral stuff like walking her more and other tricks, these pills were my last hope before getting a crate. But alas, I came home and my apartment was once again torn apart by my love who had gone through angst at my new job taking me away from her all day again. I am sad to say it didn't work for me.

I tried on my sheltie mix 20lb. Started with 1.5 tablet for 2 weeks, then upped it to 2 tablets for 1 month. Saw no difference in her hyperactivity.

I have a 2 year old basset hound who was separation issues, so during the day he is calm, but at night when I leave him he cries and barks constantly. I'm a college student and the only sleep I have gotten the past few weeks is in class. I really got my hopes up. I saw all these amazing reviews, went to the store, and bought three bottles. All excited I'd be able to sleep, I gave him 2. Sure enough....I spent the next three nights awake. This didn't effect my dog at all. Total waste of money, and now I'm sleepy, broke, and disappointed. I love my puppy, but I need to find a way for him to stop missing me!

I have a 6 mnth old red nose pitt bull terrier. She never really had separation anxiety up until recently. I got a call from my wife that our puppy destroyed the carpet. and the only thing different was I was at work. So i read about and bought these pills and they are a huge help and relief on my puppys heart.

i bought this when we adopted our 6 year old retriever mix from a shelter. she was stressed at first and two relax pills made all the difference. she could settle down and settle in. 6 months later she had to be spayed at the same facility she was adopted from (where she had been for 2 months prior to our adopting her). she was again stressed and regressed when she came home. once again, these pills saved the day. AND THEY ARE ALL NATURAL.

I have a year old Dachshund/Lab mix, she is ADD, nervous, hyper. I have tried everything, even prescription meds, nothing has worked. I read the reviews on this product and had high hopes. I gave her the dosage for an 11-50 lb dog (she is 20 lbs), and no results from the GNC product except maybe a couple of yawns.

Our cocker spaniel was out of control. She barked constantly and was so hyper that we couldn't control her. We were at our wits end. I went online to look for something and found this. We gave her 2 pills to start and within the hour she was a new dog. Neither of us could believe it. She is focused, quiet, and so well behaved it's like aliens switched her with another dog. Please try this no matter what. You won't believe the results. I give her 1 tablet three times a day. When she is without it, her behavior reverts. I NEVER want to be without this pill.
Pros: easy to administer, works great, taste, price

I have a very stubborn, bloodhound. She hates being groomed. Just bringing out the nail clippers, ear cleaner or shampoo she will run for her life. But Gave her three of these and within a few hours she was completely calm when I brought these items out. She won't let you hold her paw if she see's nail clippers in your hands. I clipped all her toe nails (haven't clipped them in almost 2 years) and she was calm she wasn't anxious, then after I gave her a bath in the bath tub (used to put her in our shower so I can keep a hold of her) and cleaned out her ears. With no stress, by the end of the day I wasn't soaked by giving her a bath or scratched I was so amazed. But she didn't care for the soft treats, The texture is like tafy so we switched from the treats to the pills which she likes much better. And Although it may not work for some dogs but it certainly worked for my Mia and I'm thankfull it did.
Pros: price, easy to administer, works great
Cons: Taste

These treats smell great and my dog is very interested in them, but the caramel chew like consistency is a big negative for her and me. She would begin to chew and then spit it out, leaving a sticky spot on my carpet or furniture. She would go for it again, chew for a minute and spit it out again. Breaking it into smaller pieces didn't help. She will eat it if I put it in a piece of cheese, but this doesn't work if I want to give her more than one, as I don't want to keep giving her cheese. I could probably get it in a pill pocket, but at this cost, they should be self-contained. It might be better for a different dog. The first time we gave her one, it worked well. The second time, the effect lasted a much shorter period of time.
Pros: works great, taste
Cons: price, Hard to Administer

I have a twelve year old Maltese that has all of a sudden developed separation anxiety. He is fine during the day but when bed time comes around and he can't be with myself or my husband he turns into a different dog. Lots of whining, heavy panting, barking - pretty much like having a panic attack. I have been giving him the Relax soft chews for the past 5 nights about an hour before bed time and the results are amazing! No whining, no heavy panting and no barking! He sleeps through the night and is perfectly fine in the morning. Thanks to GNC and Pet Smart!
Pros: easy to administer, works great, taste

We have an American Staffordshire/Boston Terrier Mix. He was having severe issues with seperation anxiety. The freak out howling (it sounded like crying) and destructive behaviour was starting to get worse. He had torn up a very large pet bed in his crate and was doing a job on the blanket we put in the crate. He had stated to chew the seat cushions on our sofa! We had sprayed everything down with bitter spray to no avail. I decided to give these a try. Within 20 minutes I noticed he seemed calmer. When I got home after work in the early afternoon his bed was still intact and he didn't do the panic howling. We have continued to use these for the last several days with great success! I really think that the Relax tablets were the ticket for us. I would recommend this product to anyone.

She didnt have an attack!!!

My aunts dog used to have these panic attacks where she would go into these seizure type fits everytime she would goto the vet or groomers. We tried benedryl and other help aids but nothing helped. She picked this up as another attempt to ease the fits. I was surprised to see when my aunt dropped off her dog that we didnt have to go through her typical routine of letting her have a fit. Instead she was HAPPY to be at the groomers and showed everyone her true happy personality! I reccomend this to anyone that has a dog that experienced these panic/anxiety seizures.
**My aunts dog had undergone all testing to rule of actual seizures- her attacks were related to anxiety/panic attacks.

My dog is a Jack/Chi and she loves these as a treat but this product doesn't relax her at all with her seperation anxiety. Actually it gives her more energy. I've tried this product for a month and have seen no results. I really wouldn't recommend buying this.
Pros: good as a treat
Cons: doesn't work for hyper dogs
