Im traveling with Izzy tomorrow via plane to Tennessee. The last time we traveled in December 06, he was 4 months old and did really well. Now he's almost a year and a 1/2 and is more energetic and aware than he was before.

I heard that some people give their dogs benadryl to calm them down. Is this okay to give a Yorkie? If not what do you suggest?
Thanks!
