I'm interested in others suggestions too. I was trying w/ (at the time) a 5.5 m.o. tib terrier. I used Epimedium powder and added Gui Ban. The client noted a nice personality change and maturity/focus with the Epi., but diuretic effect with the Gui Ban. But, at 10 mos, still cryptorchid until we surgically resolved that.
Any others that were successful?
