Hi, I have no experience with using liquid Benadryl but I would say that if your vet knows Lilly and her weight as well then the amount he said to use should be fine. I think I was told once to use children's Benadryl but I never did use any. Would that be what the vet wants you to use? Hope you get help for her on those car trips. But I have also read on here that there are other calming items you can use for these times with her.
