well ive taken my dog on a couple 10hr + trips and he does pretty good. believe it or not, dramamine is the way to go. i give him a half of a pill and he seems to do really good. my vet ok’d it and ive had no problems with him with it. hes a sheppherd and about 70 lbs and the half tab did it good.
im actually moving to texas on wed so ill be doing the same thing for him again
