Dogs love these chews and they really help with the over anxious ones!
My parents have two high strung pups who bark A LOT plus one can become a bit aggressive. Calming chews have helped a lot with both of these problems. It is also a good deal to buy directly from GNC!

Works great!
My Yorkie loves the taste of the chews. They really see: to calm him when we give them to him. They relax him and help him not to be so stressed out when we have to leave him. Great product! We like it so much that we got onto the auto ship for them.

Waste of 30 dollars.
These treats have the consistency of a tootsie roll for dogs and my dog wont even consider it bc it gets stuck in her teeth. Shes a bad car traveler so I was hoping these would help, especially because she is not picky but these were a HUGE waste of 30 dollars. I would recommend trying something else.

Very impressed
We have a 37 lb dig that someone just dump along the interstate and he is deathly afraid of storms. After 2 night's of no sleep, I picked up Ultra Mega chewable. Thought storms were done when for home with them so took his thunder coat off. 30 mins later I heard thunder and it's started all over again. Gave him 2 pills and within about 15 mins he was laying on his bed. I feel asleep right away, so it must have worked because he let me sleep all night. Said to say but can't wait till next storm to try again and not sleep thru it.

Only reason i didn't give this five stars is because i prefer the paste version of this formula. I have a 5 pound chihuahua and it is much easier to give to her as a paste (before or on the plane). She just licks it up!! But i cant find the paste anymore. Not online or in the store and its made it difficult to travel. PLEASE BRING BACK THE PASTE VERSION!!!!!!

Calming Chews
I have two older dogs that have gotten a little strange with age. They are now afraid of thunderstorms and loud noises. These chews are wonderful. Takes about 15 minutes to get into their system but work really well. And they love eating them. In fact, sometimes, I think they are acting afraid just to have them. Just like a little kid

I have been trying to find something to calm my Papillion down and these seem to have worked the BEST.
They also work great for a dog that has had surgery in order to keep them calmer.

Finally, an answer. Amazing.
I have strugged with sleep deprivation because my 13-1/2 year old dachshund (who is blind and mostly deaf) has had his internal clock set to wake up at 4:30am for about the last 4 months. I have tried benadryl, melatonin, and trazodone without success. It all helped him fall asleep and sleep well, but he was still up at 4:30 am at the latest (sometimes earlier).

Last night, I gave him 2 of these chews at bedtime (he weighs 18lbs) and I had to wake him up at 6:30am. He woke up well and ate his breakfast, so I was glad to see that he wasn't loopy or "drugged".

I am only planning to use these chews in an effort to reset his internal clock. This product is seriously the only thing that has worked and I think I am finally going to be able to get some sleep. :)

Ultra Mega Calming Formula for dogs. How long before it takes effect?
A shopper on Jun 6, 2016
BEST ANSWER: I press them flat and it seems to work quicker that way. About 15 minutes or so.
Can these be used long term?
A shopper on May 4, 2016
BEST ANSWER: I use them when needed. I don't use them on a daily basis but I do believe they can be.
How long does it last?
A shopper on Mar 13, 2018
BEST ANSWER: We use it for thunder and lighting storms. It usually will work for at least 1,5 to 2 hours for a storm.
Roughly how many chews per bag?
ERo d on Sep 27, 2018
BEST ANSWER: I believe there are 60 in a bag. You give the dog a certain number a day based on their weight. My parents' dog is about 60 pounds and he does well on 2 a day.
How often can these be given throughout the day?
A shopper on Apr 6, 2018
BEST ANSWER: It says not to exceed more than 6 a day. It doesn't have a time limit from giving 1 time to the next. So I guess I would judge that on the affect that you're getting. If you've already dosed the weight limit amount, you could give 1 more every so often to keep the pet relaxed since it will already have it in it's system until you reach the maximum daily limit. As with everything in life, use common sense & your best judgement as to how the dog is reacting.
