Hello and welcome to JustAnswer. A few questions will help me get a clearer picture of the situation:
I am flying in cabin with my dogs and I was told that I could give them Children's Benadryl to sedate them. Do you think this is safe? Last time I flew with them, I did not give them any medication and they were very anxious and panting throughout the entire flight. Yes, the liquid Benadryl is 12.6mg in each 5ml serving.
