It's the only thing that keeps us sane with a very fussy, elderly English Bulldog.  I also passed a few on to our friends & they have also done the same with their friends.  I think this company owes me some kick back!  Ha!  Seriously though when our baby boy gets fussy for whatever reason this helps a ton.  It calms him down & sometimes he will even take a nap.  Our friend's dog has issues with storms & other events & she can't believe how much better this works for her little guy than some sad prescription or the thunder coat (seen that but never used it).  Worth every penny to try.  I suggest going with the lower dosage first.  According to the ingredients I would dare say it's almost like giving your dog a Thanksgiving dinner & a beer.  Snooze central.
