I've never heard of the Transfer Factor, I'll have to check it out. I've had 2 dogs in the past that have had cancer, but I'm like you as long as they feel good & you can slow down the cancer, go for it. I know there are supplements out there that will help with the cancer but I don't know what they are. I'm so glad I've gotten her to this holistic vet, I know I can't keep her around forever but I know she is feeling better.
