I have a young dog that still gets VERY very car sick. Like puking all over the car even if we just take a 10 minute ride... she just pukes and pukes with no let up. Soo... heres my delima... We have to take her to Maine this weekend.(dont have a dog sitter..) Its a 4 hour drive. It aint gonna be pretty. And i'm worried about her getting so ill it will be dangerous for her. When she was a pup the vet suggested Dramamine or Benadryl.. WHich would work better and how much do i give he? I dont even know her weight anymore.... dont have a scale big enough here to weigh her on. I know shes gotta be over 50lbs already... Thanks for any help..
