Answer:
I hope some one lets us know....I was thinking I'll try some Kava Kava or St Johns wort for my dogs anxiety....works for me...
St John's and Kava can have very dangerous interactions with other drugs and substances. Kava is very controversial and has caused complete liver failure even with short term use. The NIH reports that damage can happen in mere weeks and has required transplant to treat. It's use for dogs, who can't tell you they feel symptoms is unwise.
