I went down and had a nice long conversation with our Vet, the one I thought was still on vacation, and I'm feeling much better. At this point and with all the work that's been done with my pups I feel comfortable giving them this new drug. I did let her know what the other vet said about purebred GSDs not being affected by the MDR1 gene, so hopefully she is corrected on that in the future.
Gonna have more questions but will start a new thread.
