Angie is not your typical German Shepherd. I have raised GSD dogs for thirty years and have never seen one as hyper as this girl. When she gets real excited there is no getting through to her. It’s as if she tunes the whole world out except for the object of her excitement.

I have worked with vets, both holistic and traditional. We have been to behaviorists and have tried everything I could think of with no results. While reading a book on amino acids, I came across the description of l-Tryptophan and read what it has done for humans with personality disorders. I ordered your L-TryptoPet and I must tell you that your products have worked wonders for my dogs again.” -Lynn Eastman (Tucson, AZ)

This was recommended to me by a friend who runs a holistic pet supplies store. It works great for moderate pain control or to make pain meds such as Tramadol work better. Also works well on depression in your furry companion.” –Met1219 (Amazon.com Customer)
