I was nervous about giving any type of mood altering snacks to my 3 dogs - I came across these at Petsmart right before they switched to a different product line (BOO!) - I was dropping my dogs at the PetHotel and they were very stressed because it is not often that they are away from me - A few of these little snacks and they mellowed out. -- Now I order them through Amazon b/c Petsmart no longer carries them.  I work from home and there are some days that my youngest dog is pretty hyper. I cannot have that while I am working b/c I am speaking to clients over the phone and they are not to know that I am not actually sitting in the corporate office -- on extra hyper mornings I will give him a could of these and after a few minutes he has settled down -- they also work great with the anxiety that my dogs get during monsoon season.
