Susan, I have sort of wondered myself about the flax and from things I have read up on. Yes, Duke had all of his puppy shots, plus everything again at 1 year. Our conventional vet gave him those--we no longer see her. He is just a little over 2 now. As far as holistic vets in this area goes, we are presently going to one now over in Simpsonville, KY who does have diet and a few other things I believe listed. I think there is only one more in the Louisville area that does holistic. I will check out these other oils. There is an Apache Indian woman here in New Albany that does and carries A LOT of holistic stuff (that is where I got the "essential oils" from) so she may have some of these other oils that you mention. I will definitely look around for alternatives. Thanks, Paula
