Ultra Mega Relax does work
I was skeptical at first but after spending the whole night with no sleep we decided to give it a try on the shepherd we had adopted he was almost a year and we were his third set of owners he was malnourished and had been left alone in a yard,given no formal training so he was out of control. Bought it and gave him his dose on the way home when we pulled into the drive way he was calm and quiet and has been that way for several hours now. I do Believe this will aide in helping him adjust to a new home an adjusting to being trained.

Work very well, our dog loves them!
We have a cairn terrier yorkie mix (4 years old) that every once in a while just can't calm down for the night. He has two brothers and they all go into the kennel for sleeping and sometimes, 10 minutes after my husband and I are settled in to bed, he'll start barking. Soft at first, then to the point of constant screeching. Giving him one of these chews about half an hour to an hour before they go to bed does the trick. He loves the taste and within half an hour we see he is ready for sleep. Highly recommended!!

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 Relax Works
I was so glad to find a product that helped my dog with car sickness. However, he will not eat the chew unless mixed in with his food. Improvement of taste is needed.

No Good
I tried this for my dog who has anxiety to help him calm down before going on car rides and when leaving him alone. I decided to give him one to try while I was home first. After 45 minutes there was no difference in his behavior and he threw up 3 times. Waste of money. Not to mention the smell is horrible.

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.

Texture odd and smell not great!
I boguht these because GNC had them marked down to [$] a bag...yes you heard me .[$] a bag!! So I thought I had hit the jackpot since they are normally [$]! My dod does not eat these alone, even mixed in with her food she ate around them...and let me tell you she is a scavenger and eats everything!!! I have to chop them up into small bites and mix them with wet food in order for her to eat them! I guess still a great deal but if I had paid [$] I would be very upset with the results. Can not tell if it realxred her..she is pretty easy going anyway.
